melmu, I recommend that you scan the list of Chad's videos, and identify any topics for which you can't say, "wow that is the easiest topic in the world and I will never get a question wrong on it" on fastplay, while making notes on the basic concepts. Do the quizzes until they are extremely easy for you.
I took the DAT a few weeks ago (Gen Chem 26/Orgo Chem 26) and I found that Chad's videos and quizzes were definitely the best go-to review source. It's getting near your test date, but in my opinion once you have taken a few practice tests and gotten used to the feeling of the test, it's MUCH more important to review the topics that are giving you trouble.
Like I took 3 bootcamp tests and I realized that I was consistently dropping 3 questions each exam on developmental bio, which I knew nothing about. So I read through that Cliffs Bio chapter again and took amazing notes, and I'm pretty sure I never dropped a question developmental again.
