Not a bad concept. I already do something similar

I already use LLMs to quiz me on books that I'm reading. The current book I've been studying is "Computer Networking: A Top-Down Approach (8th edition)." Obviously since it is a text book, there are homework problems and other discussion points. However; it's also fun to ask grok/chatGPT to quiz me on previous chapters and correct my answers.

There's plenty of conference talks posted on YouTube that I've watched over the years. Next talk I watch I will probably test out being quizzed by LLMs.
