I mean given the fact that the new MCAT is coming out and current review books will be pretty much obsolete next year, how much should I really pay for a used set of Berkeley Review Books or Examkrackers? I mean I'm kind of shocked to see TBR sets listed for $200 on the classifieds when they will have no resale value in a couple months. I already have other study materials- should I start with those now and wait until the price drops or should I just buy them now because it won't change much?
