Here is some of the feedback we have received about Devin's lecture videos:
"Hello I am a high school student in AP calc. I had problems with my teacher and understanding the way he has explained the lessons. You have single handily saved my year in this class. I just wanted to say thank you and you are making a huge difference in my schooling."
"Really well done! Thanks for your help - I'm feeling confident about my test today."
AMAZING TEACHING SKILLS. I like how you explain every step and "dumb down" even simple calculations so we see
where you got answers from. I looked at a lot of other videos, this is fantastic. "
