“I got a 25 AA on the DAT. I largely attribute my high general chemistry and organic chemistry (24 in each) to Chad's prep. His videos for organic chemistry are insanely helpful. His practice tests for all subjects helped me so much. I used his prep for the last few weeks before my test and I think it just really solidified the concepts and types of questions that were on the test. Also, just as a human being Chad seems like a great person. His empathy and care really come through in the videos and I'm glad I found his prep material. ”
