Kaplan, Princeton Review, or Barrons?
Say I only have about 2 weeks to study and am aiming for …not perfect, but very very close to it (so very close to an 800).
By the way, before summer I had signed up to take the AP Biology test and I self-studied with Cliffsnotes and Princeton Review (but the AP Bio version)…yet I forgot most of the material 
D16 took SAT Bio (E) in October and got an 800. She only used Barrons. She felt that Barrons was harder than the actual test and prepared her well.
I used Barrons for the Bio (E) test as well. No, i would say it’s inadequate. I wished I used all three of them when I studied for the test.
