Tools like ChatGPT, Gemini, Claude, and Microsoft Copilot have made AI accessible to almost everyone. Today, a student can use AI to understand a topic, a marketer can use\u00a0<\/span><a href=\"https:\/\/ivyproschool.com\/courses\/iit-generative-ai-course\" target=\"_blank\" rel=\"noopener\">AI<\/a><span style=\"font-weight: 400;\">\u00a0to write campaigns, a developer can use AI to generate code, and a business leader can use AI to analyze reports.<\/span><\/p><p><span style=\"font-weight: 400;\">But as people started using AI more seriously, one major challenge became clear.<\/span><\/p><p><span style=\"font-weight: 400;\">AI can sometimes give answers that sound confident but are not completely accurate.<\/span><\/p><p><span style=\"font-weight: 400;\">This becomes a serious issue when AI is used for business, legal, finance, healthcare, education, or internal company processes. A generic answer is not enough. The AI system must be able to answer from the right source, using the right information, and preferably with reference to trusted documents.<\/span><\/p><p><span style=\"font-weight: 400;\">This is where <\/span><b>RAG in <a href=\"https:\/\/ivyproschool.com\/courses\/iit-generative-ai-course\">AI<\/a><\/b><span style=\"font-weight: 400;\"> becomes important.<\/span><\/p><p><span style=\"font-weight: 400;\">RAG stands for <\/span><b>Retrieval-Augmented Generation<\/b><span style=\"font-weight: 400;\">. It is one of the most useful approaches in modern artificial intelligence because it helps AI systems generate answers based on relevant and trusted information. Instead of depending only on what the model already knows, RAG allows the AI to first search for the right information and then generate an answer using that information.<\/span><\/p><p><span style=\"font-weight: 400;\">In simple words, <\/span><a href=\"https:\/\/ivyproschool.com\/courses\/iit-generative-ai-course\"><b>RAG in AI<\/b><\/a><span style=\"font-weight: 400;\"> helps make AI more accurate, updated, and useful for real-world applications.<\/span><\/p><h2><b>What is RAG in AI?<\/b><\/h2><p><b>RAG in AI<\/b><span style=\"font-weight: 400;\"> means Retrieval-Augmented Generation. The term has two important parts: retrieval and generation.<\/span><\/p><p><span style=\"font-weight: 400;\">Retrieval means finding relevant information from a source. This source can be a PDF, website, database, knowledge base, company policy document, research paper, Excel file, product manual, or any other document.<\/span><\/p><p><span style=\"font-weight: 400;\">Generation means creating a human-like answer using a Large Language Model, also called an LLM.<\/span><\/p><p><span style=\"font-weight: 400;\">When these two steps are combined, the AI first retrieves the most relevant information and then generates an answer based on it. This makes the response more grounded and context-specific.<\/span><\/p><p><span style=\"font-weight: 400;\">For example, suppose a company has an HR policy document. An employee asks:<\/span><\/p><p><span style=\"font-weight: 400;\">\u201cCan I carry forward my unused leaves to next year?\u201d<\/span><\/p><p><span style=\"font-weight: 400;\">A normal chatbot may give a general answer based on common HR practices. But a RAG-based system will first search the company\u2019s actual HR policy document, find the section related to leave carry-forward, and then answer based on that exact document.<\/span><\/p><p><span style=\"font-weight: 400;\">This is the main value of <\/span><b>RAG in AI<\/b><span style=\"font-weight: 400;\">. It allows AI to answer using your own knowledge, not just general internet-level knowledge.<\/span><\/p><h2><b>Why was RAG needed?<\/b><\/h2><p><span style=\"font-weight: 400;\">Large Language Models are trained on massive amounts of text. They learn language, patterns, concepts, facts, and reasoning styles from this training. That is why they can answer many types of questions.<\/span><\/p><p><span style=\"font-weight: 400;\">But they have limitations.<\/span><\/p><p><span style=\"font-weight: 400;\">First, they may not know the latest information. If something happened after the model\u2019s training period, the model may not have that knowledge.<\/span><\/p><p><span style=\"font-weight: 400;\">Second, they do not automatically know private company data. For example, an AI model does not know your company\u2019s latest sales policy, HR handbook, project report, legal contract, pricing sheet, training manual, or customer support process unless you provide it.<\/span><\/p><p><span style=\"font-weight: 400;\">Third, LLMs can hallucinate. This means they may generate information that sounds correct but is actually wrong or unsupported.<\/span><\/p><p><span style=\"font-weight: 400;\">Fourth, in business use cases, users often need source-based answers. They want to know where the answer came from. A generic response is not enough.<\/span><\/p><p><span style=\"font-weight: 400;\">Because of these limitations, businesses needed a method to connect AI models with trusted knowledge sources. That method is RAG.<\/span><\/p><p><span style=\"font-weight: 400;\">The goal of <\/span><a href=\"https:\/\/ivyproschool.com\/courses\/ai-for-beginners-course\"><b>RAG in AI<\/b><\/a><span style=\"font-weight: 400;\"> is not just to make AI sound smarter. The goal is to make AI more reliable, contextual, and useful for practical work.<\/span><\/p><h2><b>How does RAG work?<\/b><\/h2><p><span style=\"font-weight: 400;\">A RAG system may sound technical, but the basic process is easy to understand.<\/span><\/p><h3><b>1. Documents are collected<\/b><\/h3><p><span style=\"font-weight: 400;\">The first step is to collect the knowledge sources. These may include company documents, PDFs, SOPs, manuals, FAQs, website pages, policy files, contracts, reports, or training content.<\/span><\/p><p><span style=\"font-weight: 400;\">For example, a customer support team may collect product manuals, troubleshooting guides, return policies, and common customer questions.<\/span><\/p><h3><b>2. Documents are broken into smaller parts<\/b><\/h3><p><span style=\"font-weight: 400;\">Large documents are difficult to search and process at once. So they are divided into smaller sections called chunks.<\/span><\/p><p><span style=\"font-weight: 400;\">For example, a 100-page document may be divided into smaller paragraphs or sections. Each chunk contains a specific piece of information.<\/span><\/p><p><span style=\"font-weight: 400;\">This step is important because the system needs to find the exact section that is relevant to the user\u2019s question.<\/span><\/p><h3><b>3. Text is converted into embeddings<\/b><\/h3><p><span style=\"font-weight: 400;\">The next step is to convert the text into embeddings. An embedding is a numerical representation of meaning.<\/span><\/p><p><span style=\"font-weight: 400;\">This helps the AI system understand similarity between ideas, even if the exact words are different.<\/span><\/p><p><span style=\"font-weight: 400;\">For example, the question \u201cWhat is the notice period?\u201d and a document section that says \u201cEmployees must serve 60 days before resignation\u201d may not use the same words, but they are related in meaning. Embeddings help the system find that connection.<\/span><\/p><h3><b>4. Embeddings are stored in a vector database<\/b><\/h3><p><span style=\"font-weight: 400;\">The embeddings are stored in a vector database. A vector database allows the system to search by meaning rather than only by exact keywords.<\/span><\/p><p><span style=\"font-weight: 400;\">This is different from traditional search. A normal keyword search looks for matching words. A vector search looks for matching meaning.<\/span><\/p><h3><b>5. The user asks a question<\/b><\/h3><p><span style=\"font-weight: 400;\">When the user asks a question, the system also converts the question into an embedding.<\/span><\/p><p><span style=\"font-weight: 400;\">Then it compares the question with all stored document chunks and finds the most relevant pieces of information.<\/span><\/p><h3><b>6. Relevant information is retrieved<\/b><\/h3><p><span style=\"font-weight: 400;\">The system retrieves the best matching chunks from the knowledge base.<\/span><\/p><p><span style=\"font-weight: 400;\">For example, if the user asks about refund rules, the system retrieves the refund policy section.<\/span><\/p><h3><b>7. The AI generates the answer<\/b><\/h3><p><span style=\"font-weight: 400;\">Finally, the retrieved information is given to the language model along with the user\u2019s question. The model uses this information to generate a clear and natural answer.<\/span><\/p><p><span style=\"font-weight: 400;\">This full process is what makes <\/span><a href=\"https:\/\/ivyproschool.com\/courses\/ai-for-beginners-course\"><b>RAG in AI<\/b><\/a><span style=\"font-weight: 400;\"> so powerful.<\/span><\/p><p>\u00a0<\/p><p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-13298\" src=\"https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/7.jpg-3-300x75.jpeg\" alt=\"\" width=\"300\" height=\"75\" srcset=\"https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/7.jpg-3-300x75.jpeg 300w, https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/7.jpg-3-1080x271.jpeg 1080w, https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/7.jpg-3-150x38.jpeg 150w, https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/7.jpg-3-768x192.jpeg 768w, https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/7.jpg-3-1536x385.jpeg 1536w, https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/7.jpg-3.jpeg 1920w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p><h2><b>A simple example of RAG<\/b><\/h2><p><span style=\"font-weight: 400;\">Let us imagine a training institute that has hundreds of pages of course content, placement policies, project guidelines, FAQs, and student support documents.<\/span><\/p><p><span style=\"font-weight: 400;\">Students often ask questions like:<\/span><\/p><p><span style=\"font-weight: 400;\">\u201cWhat is the project submission process?\u201d<\/span><span style=\"font-weight: 400;\"><br \/><\/span><span style=\"font-weight: 400;\"> \u201cHow many doubt-clearing sessions are available?\u201d<\/span><span style=\"font-weight: 400;\"><br \/><\/span><span style=\"font-weight: 400;\"> \u201cWhat is the placement eligibility rule?\u201d<\/span><span style=\"font-weight: 400;\"><br \/><\/span><span style=\"font-weight: 400;\"> \u201cWhich tools are covered in the course?\u201d<\/span><span style=\"font-weight: 400;\"><br \/><\/span><span style=\"font-weight: 400;\"> \u201cHow do I prepare my portfolio?\u201d<\/span><\/p><p><span style=\"font-weight: 400;\">Without RAG, the institute may need support staff to answer these questions manually. Students may also waste time searching through long documents.<\/span><\/p><p><span style=\"font-weight: 400;\">With a RAG-based <a href=\"https:\/\/ivyproschool.com\/aihelpcenter\/ai-for-product-managers\/best-ai-tools-2026\">AI assistant<\/a>, all these documents can be added to a knowledge base. When a student asks a question, the <a href=\"https:\/\/ivyproschool.com\/aihelpcenter\/ai-for-product-managers\/best-ai-tools-2026\">AI assistant<\/a> retrieves the relevant document section and gives a direct answer.<\/span><\/p><p><span style=\"font-weight: 400;\">This saves time for the support team and gives students faster responses.<\/span><\/p><p><span style=\"font-weight: 400;\">This is why <\/span><b>RAG in AI<\/b><span style=\"font-weight: 400;\"> is becoming so important for education, training, customer service, and enterprise knowledge management.<\/span><\/p><h2><b>Why RAG matters in AI<\/b><\/h2><p><span style=\"font-weight: 400;\">RAG matters because it helps AI move from generic answers to trusted answers.<\/span><\/p><p><span style=\"font-weight: 400;\">Most businesses do not just want an AI that can write good English. They want an AI that can understand their documents, follow their policies, refer to their data, and support their workflows.<\/span><\/p><p><span style=\"font-weight: 400;\">RAG makes this possible.<\/span><\/p><h3><b>1. RAG reduces hallucination<\/b><\/h3><p><span style=\"font-weight: 400;\">One of the biggest concerns with AI is hallucination. A chatbot may produce an answer that sounds polished but is not based on facts.<\/span><\/p><p><span style=\"font-weight: 400;\">RAG reduces this problem by giving the AI relevant source material before it answers. The model is not forced to guess. It can use retrieved information from trusted documents.<\/span><\/p><p><span style=\"font-weight: 400;\">This does not mean RAG makes AI perfect. But it improves reliability significantly.<\/span><\/p><h3><b>2. RAG connects AI to private data<\/b><\/h3><p><span style=\"font-weight: 400;\">A public AI model does not automatically know your company\u2019s internal documents. But with RAG, an organization can connect AI to its own knowledge base.<\/span><\/p><p><span style=\"font-weight: 400;\">This is useful for HR policies, finance reports, legal contracts, product manuals, sales playbooks, compliance documents, customer support FAQs, and internal training content.<\/span><\/p><p><span style=\"font-weight: 400;\">For enterprises, <\/span><b>RAG in AI<\/b><span style=\"font-weight: 400;\"> is one of the most practical ways to make AI useful with company-specific information.<\/span><\/p><h3><b>3. RAG keeps AI updated<\/b><\/h3><p><span style=\"font-weight: 400;\">LLMs are trained at a particular point in time. They may not know the latest policy changes, product updates, market prices, or compliance rules.<\/span><\/p><p><span style=\"font-weight: 400;\">RAG solves this by allowing the knowledge base to be updated separately. You do not need to retrain the entire model every time something changes.<\/span><\/p><p><span style=\"font-weight: 400;\">For example, if your company updates its refund policy, you can update the document in the knowledge base. The AI assistant can then retrieve the latest version.<\/span><\/p><h3><b>4. RAG improves trust<\/b><\/h3><p><span style=\"font-weight: 400;\">In many RAG systems, the AI can show the source of the answer. This is very useful when users need to verify information.<\/span><\/p><p><span style=\"font-weight: 400;\">For example, a legal AI assistant can show which case or clause was used. An HR bot can show the exact policy section. A research assistant can show which document supports the answer.<\/span><\/p><p><span style=\"font-weight: 400;\">This improves transparency and builds user confidence.<\/span><\/p><h3><b>5. RAG saves time<\/b><\/h3><p><span style=\"font-weight: 400;\">In most organizations, knowledge is scattered across folders, PDFs, emails, spreadsheets, websites, and internal portals. Employees spend a lot of time searching for information.<\/span><\/p><p><span style=\"font-weight: 400;\">A RAG-based assistant allows users to ask questions in natural language and get direct answers.<\/span><\/p><p><span style=\"font-weight: 400;\">For example:<\/span><\/p><p><span style=\"font-weight: 400;\">\u201cSummarize this contract.\u201d<\/span><span style=\"font-weight: 400;\"><br \/><\/span><span style=\"font-weight: 400;\"> \u201cFind the penalty clause.\u201d<\/span><span style=\"font-weight: 400;\"><br \/><\/span><span style=\"font-weight: 400;\"> \u201cWhat does our travel policy say about hotel reimbursement?\u201d<\/span><span style=\"font-weight: 400;\"><br \/><\/span><span style=\"font-weight: 400;\"> \u201cWhat were the key points from the last sales report?\u201d<\/span><span style=\"font-weight: 400;\"><br \/><\/span><span style=\"font-weight: 400;\"> \u201cWhich SOP explains the machine maintenance process?\u201d<\/span><\/p><p><span style=\"font-weight: 400;\">This can save hours of manual search time.<\/span><\/p><p>\u00a0<\/p><p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-13299\" src=\"https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/8.jpg-2-300x75.jpeg\" alt=\"\" width=\"300\" height=\"75\" srcset=\"https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/8.jpg-2-300x75.jpeg 300w, https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/8.jpg-2-1080x271.jpeg 1080w, https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/8.jpg-2-150x38.jpeg 150w, https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/8.jpg-2-768x192.jpeg 768w, https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/8.jpg-2-1536x385.jpeg 1536w, https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/8.jpg-2.jpeg 1920w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p><h2><b>Common use cases of RAG<\/b><\/h2><p><span style=\"font-weight: 400;\">RAG can be used across many industries and departments.<\/span><\/p><p><span style=\"font-weight: 400;\">In customer support, it can answer questions from product manuals, FAQs, warranty policies, and troubleshooting documents.<\/span><\/p><p><span style=\"font-weight: 400;\">In HR, it can help employees understand leave rules, reimbursement policies, onboarding processes, benefits, payroll rules, and appraisal guidelines.<\/span><\/p><p><span style=\"font-weight: 400;\">In legal teams, it can help search contracts, clauses, case laws, legal judgments, and compliance documents.<\/span><\/p><p><span style=\"font-weight: 400;\">In finance, it can help retrieve information from audit reports, loan documents, invoices, annual reports, and regulatory filings.<\/span><\/p><p><span style=\"font-weight: 400;\">In education, it can power AI tutors that answer questions from course notes, recorded session transcripts, assignments, and reading material.<\/span><\/p><p><span style=\"font-weight: 400;\">In manufacturing, it can support SOP search, machine manual lookup, quality control guidance, maintenance documentation, and safety instructions.<\/span><\/p><p><span style=\"font-weight: 400;\">In sales and marketing, it can help teams find product details, competitor comparisons, pitch decks, pricing documents, case studies, and customer success stories.<\/span><\/p><p><span style=\"font-weight: 400;\">The most powerful use of <\/span><b>RAG in AI<\/b><span style=\"font-weight: 400;\"> is in situations where people need accurate answers from large volumes of documents.<\/span><\/p><h2><b>RAG vs normal chatbot<\/b><\/h2><p><span style=\"font-weight: 400;\">A normal chatbot answers from its trained knowledge. A RAG-based chatbot answers using retrieved information from a connected knowledge source.<\/span><\/p><p><span style=\"font-weight: 400;\">This difference is very important.<\/span><\/p><p><span style=\"font-weight: 400;\">If you ask a normal chatbot, \u201cWhat is the refund policy?\u201d, it may explain what refund policies usually include. But if you ask a RAG-based chatbot connected to your company documents, it can answer based on your actual refund policy.<\/span><\/p><p><span style=\"font-weight: 400;\">A normal chatbot is useful for general knowledge. A RAG-based chatbot is useful for specific knowledge.<\/span><\/p><p><span style=\"font-weight: 400;\">That is why companies are increasingly moving from simple chatbots to RAG-powered assistants.<\/span><\/p><p>\u00a0<\/p><p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-13300\" src=\"https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/9.jpg-1-300x75.jpeg\" alt=\"\" width=\"300\" height=\"75\" srcset=\"https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/9.jpg-1-300x75.jpeg 300w, https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/9.jpg-1-1080x271.jpeg 1080w, https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/9.jpg-1-150x38.jpeg 150w, https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/9.jpg-1-768x192.jpeg 768w, https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/9.jpg-1-1536x385.jpeg 1536w, https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2021\/05\/9.jpg-1.jpeg 1920w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p><h2><b>Limitations of RAG<\/b><\/h2><p><span style=\"font-weight: 400;\">RAG is powerful, but it is not perfect.<\/span><\/p><p><span style=\"font-weight: 400;\">The quality of the answer depends on the quality of the source documents. If the documents are outdated, incomplete, or wrong, the AI may produce weak answers.<\/span><\/p><p><span style=\"font-weight: 400;\">Retrieval quality also matters. If the system retrieves the wrong chunk, the final answer may not be accurate.<\/span><\/p><p><span style=\"font-weight: 400;\">Document formatting is another challenge. Scanned PDFs, poorly structured documents, messy tables, and unclear headings can reduce the performance of a RAG system.<\/span><\/p><p><span style=\"font-weight: 400;\">RAG also needs regular maintenance. Old documents should be removed. New documents should be added. Access permissions should be managed carefully. Sensitive information should be protected.<\/span><\/p><p><span style=\"font-weight: 400;\">For complex questions, basic RAG may not be enough. Advanced systems may need reranking, metadata filtering, multi-step retrieval, knowledge graphs, or agent-based workflows.<\/span><\/p><p><span style=\"font-weight: 400;\">Still, for many real-world use cases, <\/span><b>RAG in AI<\/b><span style=\"font-weight: 400;\"> remains one of the most practical and effective approaches.<\/span><\/p><h2><b>Why businesses should care about RAG<\/b><\/h2><p><span style=\"font-weight: 400;\">Businesses should care about RAG because it turns static knowledge into usable intelligence.<\/span><\/p><p><span style=\"font-weight: 400;\">Every company has valuable knowledge hidden in documents, reports, manuals, contracts, emails, and presentations. The problem is that this knowledge is often difficult to find at the right time.<\/span><\/p><p><span style=\"font-weight: 400;\">RAG changes that.<\/span><\/p><p><span style=\"font-weight: 400;\">It allows employees to interact with company knowledge through simple questions. Instead of opening folders and reading long documents, they can ask the AI assistant and get a direct response.<\/span><\/p><p><span style=\"font-weight: 400;\">This improves productivity, reduces dependency on specific people, speeds up decision-making, and creates a more knowledge-driven organization.<\/span><\/p><p><span style=\"font-weight: 400;\">For companies planning AI adoption, <\/span><b>RAG in AI<\/b><span style=\"font-weight: 400;\"> is often a better starting point than building complex AI agents immediately. It is practical, understandable, and directly connected to business problems.<\/span><\/p><h2><b>The future of RAG in AI<\/b><\/h2><p><span style=\"font-weight: 400;\">The future of RAG will be more advanced and more integrated.<\/span><\/p><p><span style=\"font-weight: 400;\">Today, many RAG systems work mainly with text documents. In the future, RAG systems will work more smoothly with images, audio, video, charts, dashboards, spreadsheets, emails, and business applications.<\/span><\/p><p><span style=\"font-weight: 400;\">AI agents will also use RAG to retrieve information before taking action. For example, an AI agent may read a policy, summarize it, draft an email, update a CRM, create a report, and notify a manager.<\/span><\/p><p><span style=\"font-weight: 400;\">This means RAG will not remain only a question-answering technology. It will become a foundation for intelligent workflows.<\/span><\/p><p><span style=\"font-weight: 400;\">As AI becomes more common in business, professionals who understand RAG will have a major advantage.<\/span><\/p><h2><b>Conclusion<\/b><\/h2><p><span style=\"font-weight: 400;\">RAG is one of the most important concepts in modern artificial intelligence. It helps AI systems become more accurate, reliable, contextual, and business-ready.<\/span><\/p><p><span style=\"font-weight: 400;\">A normal AI model answers from general training. A RAG-based system answers from relevant documents and trusted sources.<\/span><\/p><p><span style=\"font-weight: 400;\">That difference matters.<\/span><\/p><p><span style=\"font-weight: 400;\">For students, RAG is an important concept to learn because it is used in many AI projects and job roles. For professionals, it helps explain how AI can work with company data. For businesses, it provides a practical way to build AI assistants, knowledge bots, support tools, and document intelligence systems.<\/span><\/p><p><span style=\"font-weight: 400;\">In simple terms, <\/span><b>RAG in AI<\/b><span style=\"font-weight: 400;\"> helps artificial intelligence move from generic answers to source-based answers.<\/span><\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"has_ma_el_bg_slider elementor-section elementor-top-section elementor-element elementor-element-647347c9 elementor-section-boxed elementor-section-height-default elementor-section-height-default jltma-glass-effect-no\" data-id=\"647347c9\" data-element_type=\"section\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t\t\t<div class=\"elementor-row\">\n\t\t\t\t\t<div class=\"has_ma_el_bg_slider elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-1eadd7d2 jltma-glass-effect-no\" data-id=\"1eadd7d2\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-column-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t<div class=\"elementor-widget-wrap\">\n\t\t\t\t\t\t<section class=\"has_ma_el_bg_slider elementor-section elementor-inner-section elementor-element elementor-element-107cc018 elementor-section-boxed elementor-section-height-default elementor-section-height-default jltma-glass-effect-no\" data-id=\"107cc018\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t\t\t<div class=\"elementor-row\">\n\t\t\t\t\t<div class=\"has_ma_el_bg_slider elementor-column elementor-col-33 elementor-inner-column elementor-element elementor-element-34141d81 jltma-glass-effect-no\" data-id=\"34141d81\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-column-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t<div class=\"elementor-widget-wrap\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-734afa58 jltma-glass-effect-no elementor-widget elementor-widget-image\" data-id=\"734afa58\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-image\">\n\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"415\" height=\"277\" src=\"https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2022\/09\/author2.png\" class=\"attachment-large size-large wp-image-12236\" alt=\"Prateek Agrawal\" srcset=\"https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2022\/09\/author2.png 415w, https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2022\/09\/author2-300x200.png 300w, https:\/\/ivyproschool.com\/blog\/wp-content\/uploads\/2022\/09\/author2-150x100.png 150w\" sizes=\"auto, (max-width: 415px) 100vw, 415px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"has_ma_el_bg_slider elementor-column elementor-col-66 elementor-inner-column elementor-element elementor-element-16f9c490 jltma-glass-effect-no\" data-id=\"16f9c490\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-column-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t<div class=\"elementor-widget-wrap\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-6c5e511 jltma-glass-effect-no elementor-widget elementor-widget-text-editor\" data-id=\"6c5e511\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-text-editor elementor-clearfix\">\n\t\t\t\t<p><a href=\"https:\/\/www.linkedin.com\/in\/prateekagrawal\/\">Prateek Agrawal<\/a> is the founder and director of Ivy Professional School.
