An English economics lecture, studied in Tamil
Priya is preparing for a state exam on her own. The best lecture on inflation she can find is a long English YouTube video. She pastes the link (Pro), gets the transcript and notes, and translates them into Tamil. The part on repo rate still confuses her, so she asks her notes to explain it in Tamil in simple words, then asks for a 10-question quiz to check herself. (An illustration of how the app works, not a real customer.)

(In English: the rate at which the Reserve Bank lends short-term to banks; when it goes up, interest on your loans goes up too.) (Source: Inflation lecture, YouTube, 8 Oct)
You ask: “Quiz me (10 questions)”
Example answer: "1. What does the repo rate mean? 2. What happens to loans when the repo rate goes up? ... 10. Name one tool to control inflation. Answers at the end." (Source: Inflation lecture, YouTube, 8 Oct)
You ask: “Where was fiscal deficit discussed, and in which recording?”
