I used the periodic table one time--ONLY ONCE--during my DAT. The real DAT is very very straight forward, from my experience. I shared the exact same concerns as you have hootinwoof. I went crazy after I saw the Top-Score Bio questions, and then laughed at the real DAT Bio questions. The same goes for all the sections of the real DAT. EXCEPT PAT! The angles suck on the real DAT. Do not let Top Score, Kaplan, nor Barrons fool you with their PAT-angle simplicity. Just be aware of this fact, it will be approached later in the season, don't you worry.
