Really, you should not worry about A&P at all. My school had A&P 1,2 and 3. A&P 1 was all about memorization and getting basic things down like action potentials, muscle contraction, histology, ANS, and basic anatomy like bones/muscles/integument. A&P 2 was less about memorizing hard facts as it was understanding how the various body systems work together - this was the funnest for me, it included; Brain/CNS/PNS, hematology, special senses, cardiovascular/lymphatic, and immunity. 2 was more about concepts than hard facts, but there was still a lot of anatomy and dissections. A&P 3 was almost all about concepts - Somebody could learn all the AP3 anatomy in a day. 3 was respiratory, urinary, acid/base, digestive, reproductive, and endocrine.
It sounds like a lot when listed like this, but you take it piece by piece - so it's not all that hard to learn.
