Kaplan cover just about everything.....
You don't really have to go into detail on hormones and stuff, just memorize them. They are not going to ask questions that are too deep. However, a bunch of questions Kaplan did not go over. I did well in my bio classes, that is why I still did well because I remembered them from the classes I took.
Before my test, I went over the bio MCAT notecards, I thought that helped. I think a good thing to do is to scan over some MCAT book, and read about the things DAT book didn't go over, to refresh your memory. (that is if you want to get above 21).
If you know everything in DAT Kaplan book, you should be able to get above 20.
Don't worry about the classification stuff, my DAT test did give me a few of those...trust me, not a lot of ppl will get them right anyways...
One important thing is keep things organized, don't confuse the function of chorion and amnion, or function of citric/calvin cycle, or type of repirtatory function that the earthworm etc.... Someone may forget in stressful condition, so make sure you make it clear what's what.
good luck...
