In sort of general, liberal arts-y distributives, we were often given a list of questions with "3 of these 12 will be on" or whatnot, and in those cases I would literally write out essay answers to all 12 and memorize them.
Over the top, I know, and I could have written a perfectly good essay on the spot for then if I had just studied the general topic without memorizing essays, but this ensured that I could write more down in the allotted time and it would still be coherent and perfectly, 100% organized. It matters when there's an extra little note made by your grade if you do really well, so that the highest grade you can get is not just an A.
For those kinds of exams, I found I could memorize a really long paragraph in about half an hour. Writing up the original essays would take a few hours, too.
For other kinds, where one didn't know the potential questions in advance, I'd make cue cards, which would take hours again, and then memorize those.
Man, undergrad sucked -- only once in a blue moon did I ever have any "understanding"-based courses. And those were the bomb. Oddly enough, statistical mechanics was understanding-based rather than memorization-based, and I loved that. But that was just a product of the prof.
And during undergrad, I never started studying for something maybe more than a week in advance. Let's say a week and a half, just to be safe (for those times when I'd have two exams crunched together or some such and so had to start studying for both earlier). Hell, I would never even do any reading before starting to study for the exams. And depending on the class, sometimes I'd not even go to class....
You could say I have the art of acing exams without doing jack**** the rest of the year down pat 🙂.
