Who We Are 

I have a passion to see students really understand math, science and engineering. I know how wonderful it feels when it happens. 
Before you learn from this site, you need to know who is teaching you, their background, experience and motivation. Read about me on the About page.
The Coursera online course Learning How to Learn: Powerful mental tools to help you master tough subjects is a free, ondemand course that starts right way. We have personally been through this course and highly recommend it. You can find more information about the free course in section 1 of the 17calculus learning and study techniques page.

Whoever is responsible for this website is absolutely brilliant. I don’t even have words to tell you how fantastic your website is and how much it has helped me. The person(s) who did this website is a perfectionist, because it is extremely thoughtful and, well, perfect. It challenges you so that you truly understand the material, it is thorough, and it leaves no questions unanswered.
Can I donate a little something? Sure, I am a poor student right now, but I feel a DUTY to give something for the immense gratitude I have for people who can put together an educational tool like this and so generously offer it for nothing. I am a much older student trying to get a master’s in statistics, so I can appreciate this website much more than the younger folks who take a lot of this type of online material for granted. I should not even compare it to other online math help sites. It truly is in a class of its own, and you should be very proud of this site.
Thank you, thank you, thank you!!!!
Just a quick thank you. I did indeed ace calc2 last semester, thanks in no small part to your website. I took the class online, and it was very much a "you’re on your own, good luck" type of affair. Your website was absolutely invaluable to me, and I recommend it to everyone I encounter who is struggling with calculus. Thanks again!
