Are those the 1001 Q on G chem, O chem, physics, or 101 passages verbal books? I never really finished the 101 passages although I tried my best. About those 1001Q books, I basically just took them out on subway/bus and did as many as possible on my way home everyday. They are OK, but not particularly helpful. Don't use them as your main source for MCAT prep. Good luck. 👍
