Web Sites for Students

I want to list two good websites which provide online content for students.Ofcource wikipedia is a good resource center for any student and as it is that popular i need not explain more on the same.MIT's (Massachusetts Institute of Technology) open courseware is one well known source for students . Another good resource is nptel project by IIT's to provide online content for students. Visit these sites and explore the world of information.
