I am an adult who is continuing my education. MathTV is fantastic! I especially like the variety of the folks going over the problems. For whatever reason it is more user friendly than others I've viewed. Great idea, great job!
American Allied University
I've been using your texts for the past two weeks, and the students are loving it. I actually have to remind them to get up and take a break, since each class meets in the math lab for just under 4 hours at a time. So far, they are doing great.
SUNY Columbia-Greene CC
I just love the way the material in the series is divided up in a strict succession of topics, unlike the other over-stuffed texts available. And of course the price is appealing too.
