I basically settled on an Anki-like system for cramming for tests in college. But this was a situation where I largely didn't attend class, but knew what formulas I'd need to know to pass each exam. Like clockwork, about 48 hours before an exam I'd lock myself away and make a bunch of flashcards, then spend hours rote memorizing them. It worked, and it got me through the tests, but I'd didn't really learn much.
This is NOT what Anki is for. It's called space repetition for a reason. The whole raison d'etre of spaced repetition is that you can memorize information in a fraction of the time by reviewing the information at progressively increasing intervals. If you had practiced spaced repetition, by the end of the term you would have spent a fraction of the time studying and would retain the vast majority of the information for months. If you spent a few minutes per week reviewing, you would still remember those facts today.
