i use AI to study like ALOT. im a person who just cant read slides or watch long lectures i NEED to be actively questioning the AI and work on my weaknesses so yeah what you are working on seems pretty good. id probably try it once it done if i got to find it
about the "oral defense" im gonna tell you from my experience (got a 3.8 GPA this sem just by using AI and im in engineering) the thing with AI was that you cant just jump in the topic or course unless you know where you stand. this is where i used to slides provided by the teacher and my course outline but i never myself studied from them id just send it to AI and ask it tell me where i stand and what the end goal is and then based on that id know how much ive learned. basically not blindly jumping in a lake but know how long it is, where are the curves, where id need to work on more... so its more of an active studying. if you know which goal you wanna accomplish ig on that base you can tell how much you have learned e.g you want to be able to solve a specific complex problem given at the end of the chapter, now you know what you need to understand and learn to be able to solve that problem and on that base you could evaluate "ok i can now solve THIS level of complex problem"
so to tell on the bases of oral defense the user could himself/herself define the goal they wanna achieve
hope that helps
