I think if people study for DAT early, it should be time spend sorting out and analyzing some of the diffiuclt concepts. Then, as the test nears, it is good to massively go through everything. What I mean is this. For example, if you study now, you may want to understand and sort through the osmosis concepts related to kidney, such as hypertonic, hypotonic, and isotonic. As the DAT nears, you may then try to remember the anatomy of the kidney, PCT, LOH, DCT, and CT. Studying early risk forgetting on the test day. Studying late risks not having the time to understand the material.
