I just got out of the test 30 minutes ago and Ive got to say, not a single thing I read out of cliffs helped me. Maybe my luck was just poor, but this section was just brutal. 75th percentile, but I had 91st percentile on AA.....yet going into this I felt bio was my best subject by a mile. Among the people I know, I feel only teachers know more than me. Orgo, gen chem...I thought I was weak in as I took gen chem 7 years ago (and got a D+ in the 2nd part of) and orgo I took at a non competitive local college.
The bio section was like someone kneeing me in the groin about 20 times. I really questioned whether I even deserved to be in the testing center. In fact I questioned my whole existance in the 22 minutes I spent on this section. You might say I should have spent more time on it, but whats the point of spending time on something you havent the foggiest idea about. I got a 19 but to be fair I feel I must have guessed right on a lot of things because I felt I did worse.
My recommendation to everyone is to not rely on Cliff's, destroyer, kaplan, or examkrackers(1000 questions AND audio osmosis). I did all of their test prep materials and while doing their questions I felt like I was a god among lesser mortals, hardly missed a thing. I dont know if Schaums is any better than the previous things I missed, but all I can recommend is dont rely on Cliff's/kaplan/destroyer/examkrackers for a thing unless you are really starting from zero. The few topics I did learn about in those materials did not help me on a single problem.
Maybe I got a bad test or maybe it was just my nerves...and biology being the first subject in the test. If I decide to retake it however (I was just a point short from rounding up to 22 and my gpa is really garbage) I will pick up the campbell biology book and just read it every night before I fall asleep. I will quote it like religious scripture to other people. If you want to do better than a 19 I recommend the same. To answer those questions you dont need to know facts, you need to be able to speak it as a language.
