First of all: I don't agree that group assignments are bad. Those problems are my problems, and most complex tasks in real life really benefit from, or require, collaboration. I think that universities should have more group assignments and projects, even if it would mean I'll drop out.

Second, I wasn't talking about group assignments in my post. I was talking about being too anxious to work on your own personal assignment, unless a friend has already done it and can provide confirmation.
