my bio section is not hard at all. i would say read Cliffs AND Barons (Cliffs is stronger in Evolution, Ecology and Animal behaviors and taxonomy) and Barons are better for the rest. Then do destroyer (I know glimmer would disagree to this but destroyer helped me with some questions), qvault, bootcamp and really memorize all the info in those questions and you will be set. At least for my version of the test. I would say for bio, it is more important to keep review and knowing the materials then doing practice problems. I don't know how long you will be studying for your DAT, but i would only a practice set a day (40 questions), then review cuz most practice tests do is to pretty much ask you if you have memorized that info anyway (for example like: what does mitochondria do? If you continue review your materials everyday, then you would know exactly what a mitondria does). So practice problems only help you to get familiar with the type of questions being asked. And the rest of the time is better spent reviewing materials. Reviewing until you sick of reading about it and still reviewing some more 🙂. Good luck.
