I actually disagree, it may be only me, about taking a lot of full length practice test. When I do this, it drains the energy out of me and I end up not studying for a while. I think its more important to tighten up you knowledge and prevent it from "leaking". I actually never finished a full test and finished every section of the DAT with 10 minutes left. I only did subsection tests, because of the energy concern. But I am also a fast test taker in general, usually finishing first in class. But I suggest everyone do what works for them. If they have timing issue then do it, but I never did and I just want people to know that they should be careful the last week of taking too many tests and not enough tightening up.
