Massively Empowered Classroom is an initiative by Microsoft Research to deliver the highest quality educational material to every undergraduate engineering student in India.
Microsoft already had an Android app for the service, but has just delivered a Windows Phone client.
With the app you can view new content to keep up-to-date in your classes and review older videos when revising for exams or solving problems. In addition, you can download content for offline viewing later.
Find the app in the Windows Phone Store here.
See the app screen shots below.
Thanks Azer for the tip.
