This is exactly what I used. I went through chads once and went through the quiz questions twice. Then moved onto the destroyer questions and probably went through them 3 times. Ended up with a 24GC and a 26OC.
Kaplan and Cliffs is great for bio. I also didnt go over the destroyer questions because i felt that they are to random and i was wasting my time trying to study them. Instead i used datqvault. I liked how you could study a subject in cliffs then pick the specific subject in datqvault and apply your knowledge. Ended up with a 23 in BIO.
GOOD LUCK 👍
