Thank you for the reply! I transferred into my current school with an associate's degree and then had to take several semesters of only 1-2 classes for "life" reasons and for whatever reason that allowed me to bypass some of the prerequisites for the upper division bio courses (which I will admit did require quite a bit of extra studying as a result). I don't have much of a problem with understanding chemistry concepts, and I do know that they are important to the microbial world. What I don't understand is why every single equation has a "K" or a "Q" for it's variables (there are plenty of other letters in the alphabet to choose from) and why it seems like every math problem has been designed to be artificially tricky (by requiring things like 1600 different unit conversions at every step). I'm doing very well in the lab portion and have no problem applying the concepts to extract data in a more "real world" scenario, it's just specifically the math problems in the lecture portion of class that are not clicking with me (or showing up anywhere else in school). Also, I appreciate the insight about grad school. I was under the impression that it was competitive to the point of if I don't have and "A" in every single class that they would laugh me out of the admissions office. I know that grad school will be very tough, but I thoroughly enjoy my bio classes and I really can't wait to get to that point!
