"I Love watching Chad's videos. His lectures have been instrumental in re-learning chemistry concepts that I've long forgotten! I especially enjoy how he relates the content with realistic scenarios so that I can understand the content better. The quizzes at the end of each section really help cement the content in. It's even more helpful when the explanation, along with a video is provided for each right or wrong answer. I am extremely grateful and thankful that he not only takes the time to make these videos, but he does it in such a way that it's easier to learn and/or recount past teachings. I highly recommend his videos to anyone and everyone needing refresher's for hard chemistry subjects or for those who want to gain a better understanding of content learned. Thank you so much! You're heaven sent!!!"
