I took the Biology test on the 15th too. There seemed to be a LOT of plant physiology questions to me and way too many experimental questions of course. I was doing great on time until those. I also left 20-30 blank, but somewhat strategically. About 10 of those were scattered throughout because I didn't know them and didn't want to guess and the others were in the experiment section. I did get some of those, at least.
I used a Kaplan book, which was helpful for what it covered, but there were definitely a lot more ecology and evolution topics than were in the Kaplan book. If I hadn't learn about some of those things from reading Richard Dawkins (thanks) I would have been in a lot More trouble than I already was.
I basically have no idea how I did. I guess these types of exams are hard to estimate...
Good luck to all of you.
