Take a look at its Analysis Summary to at least know what science topics you need to continue working on. For Bio especially, you need to make sure you've well masterted the following topics (> 3/4 of the DAT questions are based from here) as outlined by the ADA:
Cell and Molecular Biology, Vertebrate Anatomy and Physiology, Developmental Biology, Genetics
For GChem, take a closer look at the solutions (the calculated part especially) even if you've scored the answers correctly. Often, the alternate approaches given will help sharpen many of your conceptual ideas on topics like stoichiometry, chemical equilibria/kinetics, acid/bases, ...
Do not worry much about OChem unless your individual score in this section stays at 16 or lower. Don't rush on memorizing reactions pertaining to each major functional group. Stress more on how well you could understand the basic rules and mechanisms behind these. This study strategy will greatly help retain your OChem knowledge just as when you'll need it during the test.
