@KristenNola, yes. My cumulative was a 3.0, but when you go to LSU they only evaluate your GPA in your prereqs and carry that over into what counts toward your GPA at LSU. I wouldn't say that the first year is insanely hard. It's hard but it's manageable, I even worked part-time. But it depends on what course load you plan on carrying the first semester, what kind of student you are, what kind of support you have, what else is going on in your life, what kind of social life you want to have... it's different for everyone. I took abnormal psychology before I went there, and I strongly recommend that you get it over with because it's one less thing for you to take while you're trying to deal with physiology. If you haven't taken A&P I and II (with labs) you can elect to do that, but I went ahead and retook anatomy at LSU because I wanted the cadaver experience, and because I figured it would help me remember some of the finer points during physiology (which it did).
An A in physiology... I think I only know of one or two students who currently have them. I have a B and I think I'm still in the minority. Most people are getting a C if they aren't counting the points they need on the final to pass the course. The issue students have with physiology is that you learn the processes in class, but you have to adapt your way of thinking to how the questions are asked (which is anything but straightforward). I did pretty well on the first two exams but the exams got progressively harder and the questions got more obtuse. If he runs the course the same way he did this semester, he will have two options for exam times. ALWAYS sign up for the later time! It gives you two and a half more hours to study and get yourself in the right frame of mind, and you will be able to talk to students who just took the exam as they come out of the testing center to see how the exam was and what was on it to give you some direction as far as what you're going into. Read the chapters beforehand, print out your lecture slides to follow along (he doesn't allow laptops in class) and GET A GOOD TAPE RECORDER. A few of the lecturers are NOT the easiest to understand and you may even find yourself zoning out because it is so easy to get lost in that class, and it really is best to have a record of EVERYTHING that comes out of the instructor's mouth during lecture.
I hope I've been some help. Good luck!
