Hi has anyone used MCAT study material to prepare for the OATs? My roommate purchased the Examkrackers study set to prepare for the MCATs, but he recently changed career paths and asked if I wanted it before he sells it off. It seems like there's a lot of information and books regarding MCATs, but not so much on DAT's and OAT's. I'm under the impression that the three tests all cover the same material and concepts, but please correct me if I'm wrong. So to sum it up, is it ok to use Examkrackers MCAT study material to prepare for the OAT, or should I purchase material made exclusively for the OAT?
