I took A&P recently and utilized the book, and used "anatomy and physiology" flashcards by Scientific publishing which I ordered from Amazon. I loved the flashcards-the box is big but it is divided up by topic and I would take the flashcards for the unit we were studying and keep them in a plastic bag that I carried in my purse so I could review them while waiting in line, at the doctor, etc. Lots of students in my class asked me where I got them. I just checked amazon and they are $41 but I ordered them in January for about $16, so check other websites because you can find them cheaper somewhere I am sure.
I also looked up stuff on YouTube and watched khanacademy lectures (as someone else mentioned) as well as reviewing things like nephrons, bones, and muscles by miscellaneous other YouTube producers. One thing I have been told to study really hard is the renin-angiotensin system since that is really important in nursing ( but that is not until A&P 2).
Another thing you can do ahead of time is memorize major muscles and bones although the detail you need to know about these systems varies by school.
Good luck in your class!
