### Very Helpful

This course is a lifesaver for studying chemistry as well as going over material if it is unclear. The only complaint I have is sometimes Chad will reference something on another board that is just slightly out of frame, it would be helpful if the...

### CHAPTER 19 AND 20

These videos have helped me succeed in chemistry and love the subject itself. Super helpful!! Recommend to everyone, makes the course so much easier!!

### Great!

Chad's lectures are very helpful, I get to understand the material better than in my actual lecture.

Chad's lectures are very helpful, I get to understand the material better than in my actual lecture.

I am currently in CHM 116 at ASU and have always struggled with even some of the most basic concepts encountered in chemistry, until... I found these reviews. The way a lot of the material is presented in lectures for chem courses is overly-compli...
