Ive never commented on any of your vids yet but ive been watching them the past few months to help me in calc 2 and I just wanted to say thank you. Ive literally been completely stumped on about 80% of my course work; I watch ur vids and boom I understand it. Taking notes from your vids are more helpful then in-class notes. Your clarity may be a big part of me passing this course, so thank you!!!

You truly have a gift for explaining math. My book, teacher, and tutor cannot explain it as well as you do. Keep on keeping on.

Thank you sweet baby jesus. Finally someone who knows how to teach math. Strip it to the very basics, make it simple, step by step. Why do math teachers always have to complicate things and find different ways to "improve" the way they teach the class. Math unlike other classes is linear, theres one correct answer, and sometimes different ways to get there. Teach us the way, make it simple and snappy. This is what you've accomplished. Thank you.

You are my go to for Calc 2 studying. you teach so well I'm almost disappointed that I won't need to see Calc anymore after this semester.

You have a true gift as a teacher. And I think your choices in solving math equations are superior.

You can find the Vertex [P(h, k)] more quickly when using formula: h=-b/2a, k=(4ac-b^2)/4a.

[akabucha]

I've always watched your videos before taking quizzes in class, it helps a lot for reviewing!!
