That's a good question. I took the DAT last Christmas and I used the Destroyer. I agree with the above post. Destroyer is definitely designed to over-prepare you by asking questions that are loaded with useful info, especially for the Bio section which is notorious for throwing some curve balls at you. The Destroyer is not designed to be used for timed exam practice. In my opinion, as well as that of numerous other students that I've talked to, timed exams are a waste as you might run the danger of psyching yourself out in case you don't score as high as you want. You're better off studying using the preferred tools of your choice (I can only recommend Destroyer and Youtube videos since that's what I used). If you're worried about adequate time, I can speak for myself and others who've observed that there is PLENTY of time for the science portion of the DAT. It's really on PAT, RC and QR that you are up against the clock (particularly in RC). Also, keep in mind that for the time being ProMetric testing centers are requiring test takers to wear masks (they will not admit you without some sort of face covering). So you might want to practice your Destroyer questions while wearing a mask so that you can mentally acclimate yourself to the discomfort of breathing into the mask while trying to recall information that you studied.
