Someone on quora.com has asked:
"How do top students study?
"If you went to or are going to a top school like MIT, Harvard, Columbia, IIT, Berkeley, Stanford, Cornell, Caltech, Princeton, Yale, Brown, what is your studying method?"
There are about 41 responses so far. Some of the responses contradict each other, and I would not be able to follow some of the advice that is offered myself. But maybe you're a student and could use at least some of it.
Here. (You might need to join quora, which is easy.)
