I have looked at many review sources for chemistry over the last 4 years, Khan Academy, Crash Course, the Princeton Review, and Barron's to name but a few. Yet, none has been as helpful or as well thought-out as the one on chemistry prep. These review videos are, quite simply, masterpieces. I can guarantee that they will be of help to anyone serious about learning chemistry. Well worth the price.

When I took General Chemistry 2 the teacher was brilliant but had no understanding on how to relate the information to a student. After 16 weeks in his class I hadn't learned a thing. Chad is able to explain the material on a student level, not a Phd level, and makes the material enjoyable.

Chad's tricks and explanations to chemistry made me wish he was around when I first took it years ago. I would have aced those classes without stressing as much as I did. If you come across his review videos when you're having a hard time, watch them! His videos are the best resource you'll find for chemistry!

This course has been a phenomenal help! The way you explain the concepts makes them easy to understand and remember because your goal is understanding. The many examples throughout the lecture helps solidify the concepts, as do the practice questions. Although Organic Chem is a subject that tends to fly over my head (and at least a few others), you do well in not making it complicated, but rather simplify it and ease students in understanding this foreign language. In terms of function and aesthetics, the website is great! Une grande aide! Much thanks!
