What are the best free online resources and YouTube channels for UPSC?

High-quality UPSC preparation is entirely possible using free online resources. The key is to use subject-specific experts and official government platforms to ensure accuracy and depth.
For YouTube, Mrunal Patel is the gold standard for simplifying Economics. For Geography, Amit Sengupta offers excellent visual explanations, while Sudarshan Gurjar is highly recommended for mapping. If you need daily Current Affairs and Editorial Analysis, channels like Sleepy Classes, Study IQ IAS, Drishti IAS, and Byju's Exam Prep provide consistent updates. Additionally, Sansad TV (formerly RSTV) remains a critical resource for balanced debates on policy and national issues.
For websites and practice, Insights on India and IASbaba are essential for their daily quizzes and "Secure" answer-writing initiatives. To get authentic data on government schemes and new legislation, always refer to the Press Information Bureau (PIB) and PRS Legislative Research. If you are looking for structured notes or AI-driven mentorship, platforms like SuperKalam and ClearIAS offer free tools to track your progress and evaluate your answers.
For foundational learning, the NCERT Official YouTube channel provides reliable summaries of school textbooks. By combining these sources—using YouTube for conceptual clarity, websites for daily practice, and government portals for authentic data—you can build a comprehensive preparation strategy without expensive coaching.
