jstyt7 I see you just joined SDN. I was exactly in your shoes maybe a week ago when I made an account here and started reading forums about "Chad's videos are great!". Long story short, they are videos you have to purchase from a website called CourseSmart. They are about 50$ for a month's access. The subjects for the OAT videos include Gen Chemistry, Organic Chemistry, Physics, QR, and a incomplete version of biology. Chad (the name of the dude in the video teaching these subjects) lectures you and then also provides you with quizes that can reinforce your learning for EACH section that you learn about. His videos have helped A LOT of people in the past do good on the OAT as opposed to just reading dry material in books. I am about 1/3 through all his videos and can definitely see why. I tried reading the Kaplan book material and wanted to shoot myself in the head after 2 days of it. I'm super glad I found these forums and found out about Chad's videos. HIGHLY recommended.
