This was a special tablet application that allowed students and teachers connected over the same network to connect and study together. No more blackboards and textbooks. The application allowed teachers to select the subject they would wish to teach and also add students to the class, in which case, the student would be shown a white screen and interaction on the student side would stop, since the student would have joined a class. When the teacher would write notes, or scroll through PDFs the students would be able to see the same, and also they had the capability of writing notes, that would be attached to a session so that they could refer to the notes when preparing for the exams.
A teacher would also be able to assign a student the rights to lead the class, in which case, whatever the student does, the teacher would be able to see and so would the other students be able to see.
This is an enterprise application hence not available on the PlayStore
