New student: Should I take anatomy and chemistry together?

Hello, let me start off with a little about myself. I just decided recently to go back to school for nursing (I have my BS in psychology and have a pretty decent job, but its very stressful (I work with kids with severe behavior problelms and come home stressed at the end of the day, and some times even banged up from putting them in physical restraints! and im a pretty small girl) I have been out of school for almost four years.

My question is- does anyone have any experience taking anatomy and chemistry together and have any advice about whether or not to do it? I want to be able to start the nursing program by 2010 and if I don't take them together (or with physiology or microbiology) I wont be able to start until 2011. That just seems like a long time for a 2 year degree, when I already have all of my other pre-reqs done from my other degree. But then again I dont want to fail my first semester... Some other details about me, I am pretty horrible at math, I can usually pass anything if I put my mind to it, but I need A's in these classes, I have never taken such hard classes together, and havent taken a science in years. Anyways, thanks for your input, I just found out about this site and its great! The little icons are great too! Please! Advice! Classes start in two weeks!
