Effective learning and memorizing is actually at the narrow edge of struggling: it's neither "too easy" nor "too hard and painful". SRS systems do a very good job of tuning this: by the time a question comes back to you it will feel difficult, but you'll be able to recall the information and answer it with some effort. It's a matter of recognizing this feeling and acknowledging as "the right kind of effort" as opposed to a hopeless task.

If you ask the AI "please quiz me about the proper understanding of issues x y z and tell me if I got it all right. iterate for anything I get seriously wrong, then provide a summary at the end and generate SRS cards for me to train on" it will generally do a remarkably good job at that.
