“I just wrote the OAT (July 2020) and scored the 99th percentile. To study I used the Kaplan book and practice tests and Chad's Prep free course. I also watched a lot of Chad's physics and general chem lecture videos. Overall all Chad's Prep material is phenomenal. I would recommend to anyone, the difficulty of the practice tests for the OAT really helps to prepare you well and I think it is amazing that the course is currently free. Definitely worth it to use Chad's Prep, would recommend to everyone preparing for the OAT.”
