Prerequisite Advice

Hello,

I was hoping a few of you can give advice in how to take my classes, like the best way to juggle my schedule without over whelming myself. I am going to be leaving my job to attend school full time to get my prerequisites done so I can (hopefully) get accepted to a accelerated nursing program and attend the following year. I am not sure if I will be working part time while getting my prerequisites. The only science classes I ever took in my whole college career was biology and I completed AP1 and AP2 last year while working full time. I have to take chemistry (w/ lab), microbiology (w/ lab), nutritional science, developmental psychology, retake statistics, and possibly take biochemistry and pathophysiology for another program i am thinking of applying to. Is taking microbiology and chemistry along with two other courses in one semester doable or am I setting myself up to failure? Do you think it is better if split the two sciences up?
