Answer:

CollegeBanana was built from the idea that we students could come together and basically blog what happened in class. It's not for everyone, for instance, a lazy student who just wants the answers.

In addition to collaborating, and cherry picking notes from each other, students and professors can have their own private groups and discuss topics as they please.

Basically, for times like these, any tool to connect and not be alone is worth looking into. Try CollegeBanana out, blog some notes, tell your classmates and professors about it! Give feedback on how to improve the service.
