I really enjoyed using this tool and would have loved to have had it for previous exams as well. This is by far the best way to test my understanding of the material and have things explained to me as if I were talking to a TA. If I ever told the AI that I did not know an answer, rather than just telling me the answer, it would walk me through how to reason my way towards the answer which really helped me deepen my understanding. All in all a great product!
