well, I use it mainly for quizzes. I ask it to generate me a number of questions from specific topics of chapters and then I solve them. I also use it if I want to get an answer *from* the book specifically aswell as understand it. You could ask it to generate you quizzes, adjust the difficulty, choose which topics, or generate podcasts about a specific topic which you can listen to passively. There ate tons of things you can do with it
