I am sorry, but I am not a good adviser on that, because I took medical school anatomy before (as well as Latin language)therefore anatomy is an easy class for me. I asked my friends that are taking it for the first time, they said they would definitely take anatomy in undergrad if they would know that it would be so hard for them. Flash cards...I think learning the facts is not a problem, the biggest issue is that people do not have a general picture of organs/body in their head. Flashcards would not help you to understand better, as they are very fragmented. Just be prepared to study very hard and try to figure out the best way to study as soon as possible and you'll be fine. Lots of people are doing very well without any prior review. Relax, have fun and be prepared to work hard when the school starts!
