People that spend inordinate sums of money to go to college and then spend all their time there figuring out how to only memorize what is absolutely necessary for the tests, and nothing else, are misguided. That said, in my experience people that are interested in actually learning the material above and beyond doing well on the tests, learn it during the semester, not one night for the test. An hour refresher before the exam if you've been hitting the books all along is great if you already know the material. it reminds you of minor things that can trip you up on an exam, like some notation or some other minor detail. Cramming tends to be the symptom of very temporarily obtained information for the sole purpose of grades.
