Fundamentals in our program was the easiest test material, in my opinion. The focus was on just that, the fundamentals. I did very well that semester by taking copius notes and listening to the lectures over and over again. I reviewed my notes every day, and a lot of the tests came from those.
The more difficult critical thinking test questions didn't come until 2nd semester for the most part, if I'm remembering correctly.
Good luck, and go to the test reviews prepared
so that you can ask relevant questions that will help you understand the things you need help with!
Also, I have a study group that has been great all 4 semesters (actually, we started in pre-reqs together, A & P and Micro, etc). We have 3-4 members, depending on who can attend, and that helps too. Don't get bogged down in a social group that doesnt' study. That will only distract you and you won't make any progress.
