I frequently used spaced repition in my maths/physics courses to great success. The types of things I would memorize: - Key theorems - Proofs - Any kind of visualizations (e.g. statistical distributions) - Properties - Trig identities A lot of time in math or math heavy fields, there are a lot of tiny details and nuances. Using an SRS properly really solidifies those concepts in your head (See my comment below on manufacturing 'aha' moments). It also helped because a lot of those key concepts were immediately available in my mind and I was 100% I had them correct. Memorization reduces a lot of mental friciton.
