"""Guaranteach is powered by a vast library of short video math tutorials and a sophisticated array of learning algorithms which allows the software to intelligently guide a student at their own pace, and on their own customized path through the math curriculum. As the software learns about each student’s preferences for teaching styles, it selects the optimal tutor and video to maximize the chance of the student understanding the concept. If you’re struggling with the concept of differentiation from first principles – Guaranteach has tens of short (1-2 minute) math tutorials on the concept, all created by different teachers, with their own unique explanations, diagrams and methods for conveying the concept. Search for the one you want, or let Guaranteach recommend what’s best for you."""<p><a href="http://www.guaranteach.com/welcome/about" rel="nofollow">http://www.guaranteach.com/welcome/about</a><p>I see no reason for this idea to be applied for higher education , and for written content.
