I've been accepted to the school. I'm not sure where you're at in your classes, so I'll speak as if you haven't completed anything and try not to leave anything out. You're gonna want to keep your GPA decent. Mine was 3.7 cumulative and 4.0 science. When I applied, I only had stats and general chemistry left to complete. My advice would be to take your biology classes very seriously, and not just for a good grade. You'll be expected to understand all of it, or at least be able to recall it easily enough, for the program. Depending on where you're taking your pre reqs, you may have to take the 5 credit hour molecular & cellular bio class (Biology 121 at CCC) before being able to take micro and A&P. I thought they were making me jump through hoops and wasting my time with that class, but this one is actually very important. It's where you'll learn the building blocks necessary for A&P and micro. Also, cell bio is most definitely on the TEAS and, once you're in the program, pathophysiology will refer back to this material.
As for the TEAS, I got an 85% while sleep deprived and totally stressed about personal matters. We were told before the test that the very minimum Res accepts is a 68%. It's not a very hard test, just broad. Still, a lot of people have a hard time with it; my score landed me in the 95th percentile just to give you an idea. I think the national average was 65%. There are no calculators allowed and I would suggest making yourself comfortable doing fractions, percentages, ratios, long division, and also adding, subtracting, multiplying, and dividing with decimals. There's also some minor algebra. The science section is the largest portion, and has the widest range of topics. Know all your bio obviously, but also basic chemistry and some earth science. The other two sections are reading and english. When the time comes, I would buy the practice tests offered at the ATI website. They're about $50/ea and you're allowed to take them twice. Seems like a rip-off but the practice test was very similar to the actual exam. I used my first attempt to both observe the kinds of questions I was being asked (very important!!!) and see what areas I need to brush up on. Then I studied old class materials and nursing school
entrance exam books that many libraries have and you shouldn't need to buy. Then I took the second attempt.
I don't mean to make any of this sound like it's nearly impossible to do. It's not at all. Just stick with it and learn how to be a good student (I had to, myself). Time flew and it wasn't so bad. Just know when to make the necessary sacrifices.
I'm not sure if I covered everything you were wondering about, so feel free to ask about anything I might have forgotten to mention and I'll try to get back to you quickly.
Hope that helped, even just a little!
