If my memory serves me correctly, you have to have Bio 101 (at this school i think it was intro to human biology, but i could be wrong and GTC-web does not list prereqs) to get into A&PI. Then you have to have A&P1 completed before you can get into A&P II and Microbiology, both of which are lab classes. I know several people who took A&P II and Micro at the same time and being as they are both lab classes, you have twice as many tests. Plus you have to count on spending non class room time in the labs during open lab to prepare for the tests. It is a tough course load to carry but i know of several people who did it in style. GTC is coverting to semesters next summer, so if i were you i would definetly fill up the fall with bio intro, winter with a&p I, spring with A&P II and either summer or fal 2011 with Micro. in each of those terms i would take one of the other non-science requirements. That way you would be on track because you DO have to have all of the requirements completed before you can apply. And it would spread out the stress load. No matter how comfortable i felt with the course material, i always felt the weight of the program competition hanging over me, and probably pushed myself to extremes when it came to acheiving the grades. However, for me, it paid off.
Also, in my first post i mentioned that they consider 8 classes when looking at GPA, but i was wrong....they only require 6 classes: A&P I, A&P II, MicroBiology, English Comp, College Algebra, and Intro to Psychology. Now that is JUST to get into the program. To graduate with a degree there are other classes that are required such as Speech and Sociology and Music Appreciation. I forget about those classes because i had already completed them before applying. Those classes additional classes can be taken before or during the nursing program. For me though, i have to work while i go to school, so i was sure that i would only have nursing programs left to take so that i could concentrate my valuable study time on just that subject.
