“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 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!!”
