I had always been reluctant to use memorization but I found it helped immensely. Especially as a returning graduate student.
Also, do you continue to use it for math-like subjects?
Please read this article about learning math with spaced repetition. http://augmentingcognition.com/ltm.html
Perhaps this was a reaction to my previous approach to learning, which completely shunned memorization.
From the way you described it, you change all statements/theorems/etc. in the book into questions? To put inside you mnemosyne deck. So your deck in the end has a lot of prove this statement/theorems/etc. and the problems that come with the book.
I was expecting some magical shortcut. But it's the usual tip of doing shitton of problems. Your way is especially comprehensive of course since you basically memorize/know/practice how to prove/solve everything in a book.
Impressive. This takes a lot of time and discipline.
Great job on your exams though!
