Aye. That is what I do these days. But my long term retention rate for math formulae is nearly zero.

I just came home from a math exam. During the exam, I could recall almost every formula I had crammed last night. By tonight, I'll forget nearly half of them. In two weeks, I'll only remember 10% of the stuff I learned, and that too merely because some of those formulae were strikingly obvious or wonderfully symmetrical.

I guess I just have a terrible memory.




You're not alone in this department. Repetition is the key.
