Wow, A&P 1 in 8 weeks! Congrats on the A!
I personally though Micro was easy compared to A&P. As others have commented, it is just memorization. I had taken a basic biology class prior though. I don't think you will have a problem if you did so well in A&P. I found that a lot of the early course work is nearly identical. You begin with basic chemistry, move to the anatomy of a cell, and discuss how the cell makes energy. You will find later that the immunity units are similar. I particularly enjoyed learning about various bacteria from the perspective of the bacteria trying to live in a host (in Micro) and as a disorder in the human body (in A&P)
Again, I'm sure a good student like you will do fine
