This monster will be here soon enough. I know that reviewing past exams and previous coursework is an obvious method, but what about memorizing the content, such key equations? I see that there are a couple different ideas: (1) memorize the important equations, or (2) memorize the derivations of the equations. The second method seems best, because you understand the approximations and limitations imposed on the resultant equations. Do you guys (or girls) think the second method is feasible, or needed to perform well? How have you guys approached this aspect of the preparation?
