These videos have been so incredibly helpful to me in my first year physics courses in university. I have no physics background at all, and have been struggling big time. If I would have known that these videos were available in the first half of the year long physics course Im required to take- I would have dived right in. Thank you for these videos! I've been recommending them to everyone I meet. Thanks again, Chad! You're teaching style and examples for all of the courses you cover have been a God send to me :)

I'm taking physics 2 and I've been watching Chad for about 3 semesters now. Watching his videos has helped me pass O-chem,BioO-Chem,and Physics 1 with B's. I'm very confident that I will be passing Physics 2 with a B as well with his help. I love the way he breaks it down "Barney Style" so that you can understand it. Not everyone can actually teach what they know, but Chad does an amazing job at doing this. I recommend this site to anyone who is really trying to learn and understand. It's well worth the money!!

Chads real cool and gets straight to the point no matter what topic. His plug and chug techniques really go a long way. I took Physics 1 this summer and because of Chad I was always ahead of the game and prepared for every quiz/exam. Real props to Chad, wish I discovered him when I had taken Gen Chem.
