I have had reasonable success using spaced repetition with math proofs (written in LaTeX). I create cards sparingly, often based on questions from problem sets which I shouldn't have gotten incorrect (i.e. the mistake stems from a fundamental misunderstanding of concepts, not a misstep in algebraic manipulation)

> I don't see how cards would help me with mathematical ideas. You have to get them on a fundamental level, and then they're hard to forget.

I find it too easy to trick myself into believing I understand a concept on a fundamental level. But often that "understanding" slips away, and six months later when faced with an example problem out of context I struggle to solve it.
