What to take before DAT

Hi guys! I’m a sophomore right now and my original plan this whole time was to take my DAT this summer so everything with ochem would be as fresh as possible. When I went and met with my advisor she told me that I should take genetics and physiology in the spring to prepare for the test. She also said she wished I had more time so I could take biochemistry before the test but I wanted to know what you guys thought. Is taking generics (no lab just a one hour discussion) and physiology (no lab or discussion) with ochem 2 a bad move? Is taking or not taking any of these classes before the DAT going to make or break me?
