I was wondering if it's worth taking the Dr.Collins prep course. I have taken prep courses before for MCAT and I didn't find it really useful other than the materials given to me. Basically, I wasn't a fan of learning from an instructor because the prep book did just fine, and I don't want to waste my money. Is the Dr.Collins self study sufficient? Thanks in advance!

I would buy his materials used.
