My AP Chemistry teacher handed me "Study Guide Chemistry, 7th edition" by Zumdahl and "Fast Track to a 5: Preparing for the AP Chem Exam". On the Fast Track book it says "To accompany Chem 7th edition by Zumdahl", so supposbly the Fast track book was made to specifically supplement the Zumdahl book. I haven't really researched these 2 books and I was wondering if used together, would help me reach that 5 on the exam. So, are these 2 books adequate, or do I need to pick up PR
from our library and look over that?
