    Thank you so much, Chad! You have a gift! You're an amazing teacher. Part of why I love your chemistry course so much is how I am learning so much about teaching while learning about chemistry. I get so much more out of your videos than I do in my college chemistry class. The stuff I learn actually sticks. Thanks!

I'll be returning to Chad's videos for help in Organic, and when I prepare to take the DAT.
