“Do not worry about your difficulties in mathematics; I
assure you that mine are greater.”
-Albert Einstein
I thought this document from a different culture on “how to study mathematics” might be of interest to studying mathematics. Once you make sense out of the different language and this culture’s way of talking about studying mathematics, this document is very useful. Think about supervisors as graduate students who help you practice, and you should be all set.
