Hey guys i have been getting a quite of few private messages from everyone on this board, so i figured i would answer everyoens questions on a thread. I took the DAT and scored in the 98th percentile using all of the popular resources such as Destroyer, Topscore, Kaplan. My friends have recently switched over from doing Dental to Optometry and basically had a good set background of the material using those resources. They took a few practice OAT tests and scored very high. So i truly reccomend you guys check out these products for the OAT. Best of luck hope that helps everyone! Also to adress the question fo where they can be bought. Destroyer- orgoman.com Kaplan well ask around you might be able to get the material for a less price, the classes from my own experience were not worth it. Topscore- just search it on google it will give you a link Good Luck!
