I'm so sorry you weren't able to apply this semester. Taking microbiology will help you get more points though so that's a plus for you. Professor Spencer is great. I'm taking her class online (big mistake) but I've heard her on-campus classes are a breeze!
As far as study tips, I don't have many. All in all, I studied for about an hour. The practice test was all I did just to get familiar with the format. There were several questions from anatomy but also some from chemistry and physical science. I made my best educated guesses!
Reading comprehension and grammar are important but not difficult. Just take your time and pay attention to the details. The math wasn't as bad as I expected. Since you can't use a calculator, it's mostly general algebra. I need to brush up on my percentages.
Good luck in microbiology and keep your fingers crossed for me!!
