The key to memorization is not repeated exposure as some people think, but rather repeated testing - you’ve got to try to “make” yourself remember facts (such as A&P) over and over again, even when you can’t recall those facts, to really get it to stick. My biology professor who gave regular quizzes (that weren’t even for credit/grades) yielded students with MUCH higher knowledge retention and test scores than the profs who just lectured and gave a few tests.
He shared with me a neuro journal article that substantiated this method - I’ll try to find it if you are interested.
What I learned from this is that flashcards are an excellent way to learn (and retain) a lot of facts quickly. Don’t bother making them yourself, thats wasted time that you could be drilling. I suggest A&P cards make for medical students, then take your textbook and sort out all the cards that are relevant to the learning objectives you will be tested on.
Then its just a matter of drilling (start with just a few cards and add as you learn, don’t forget to shuffle them periodically) - just make sure you try really hard to recall the answer before you flip the card over, even if you can’t recall it - it is that attempt to remember that will cement what you see in a second when you flip the card. Never just read the question and flip over for the answer.
Go ahead and buy and take a couple of practice tests to build confidence, then knock the test out of the park. Even though the prep materials are expensive, they are high-yield compared to general college classes - the classes will teach you more (but possibly not cover some stuff on the test), but the prep materials will give you exactly what you need for the actual test.
