GradeGuru – Notes Sharing By Students For Students
http://www.gradeguru.com/

GradeGuru is, at its core, a platform for students to help each other with coursework. It’s an idea that grew out of their belief in the power of collaborative intelligence and the notion that a rising tide lifts all boats. They want to elevate the educational playing field by encouraging all students everywhere to achieve their best and to inspire others to academic heights.
