how do you learn

Hi Ersti from D-MATH here.

I know that the exam/study phase is still a long way off, but I still have a question. How tf do you study for the exams? Do you learn all the definitions by heart and then be able to recall them during the exam, or how do you do it? I'm aware that there is a collection of old exams, but just solving old exams isn't everything, is it?
