I'm shamelessly stealing from this reference

while teaching I need sometimes to point students to good studying practices. I just found a great gem. I'm going to steel this one. Professor Rapaport wrote a long page on how to study efficiently and I agree 100% with the content. It is really funny, useful and filled with some gems (i'm recursing gems in gem in gem in gem... ok... who cares, my text) Next time I get a student struggling with getting results because of bad habits, this will at the top of my list of recommendations.
