For me, pharmacology was harder. In A&P, I could make sense out of each of the body systems we were talking about in class. It was very straight forward to me, and I understood the material. Pharm on the other hand was a lot of memorization like what is the mechanism of action of this drug, what is the therapeutic level of this... and so on and so forth. I struggled a lot in that class. But I know some of my classmates excelled in that class and made and A. So it all depends on who you are. Good luck to you this semester
Pharmacology was definitely harder. A&p is ok because it actually makes sense. The body is very logical. But pharmacology is just a bunch of long drug names, genetic and name brand, that you will never remember. There are only a few drugs that will actually stick out in your mind until you deal with them on a daily basis.
