Hey there! Welcome to the family haha.
Study plans: Study 2-3 months and take the time to make your own study schedule, recognize your weaknesses and strengthen them.
Material: Cliffs AP Biology, DAT Destroyer, Math Destroyer, Klein Organic Chem books.
For me DAT destroyer was my favorite study material. It covered all the sciences really well. I made the mistake the first time not using it when I studied, and I wasn't prepared at all for taking the DAT. Don't make this mistake, if you aren't prepared postpone your test.
When do you plan on applying?
