Anatomy is a lot of memorization, and Ochem is a lot of work.
I would be hesitant to take them both together, especially not having general bio before anatomy.
To put it in perspective, my spouse tells people that I studied more when I was taking A&P than I did for any other class, EXCEPT Ochem! That should tell you something. Those two classes were the two classes that I studied the most for, then they should not be taken together!!! (Micro was a close third for studying trying to memorize all the stupid bacteria and such...)
Good luck.
