Personaly, I think a physiology class is way too detailed for what we need to know for the DAT. I took a lower level physiology class, and an upper level physiology class. The lower level class (which I highly recommend goes in just the right amount of depth required for the DAT. The upper level physiology class is way too detailed, for example, we were learning about the enzyme aromatase which converts testosterone to estrogen (I really don't think we need to know that).
A lower level Physiology class can be very helpful: We used a University Text Book for this class, but this book went into the exact amount of depth that the cambel and reece section does for 'animal form and funtion'
🙂 .
Just for comparison, the upper level physiology class I took required, 'principles of physiology', by berne and levy. It's the text book they use in most dental/medical schools

(I think).
Cambel and Reece is to Unverisity Biology
as
Berne and Levy is to Dental/Medical Physiology
Good Luck, I hope you do take a lower level physiology class in your University, (if it is offered), I'm sure you will benefit from it, or just read the cambel and reece text book on that section
