Group Projects

I really do not like group projects.  I understand that they are supposed to teach us valuable skills, but honestly the only thing I have ever learned from a group project is to trust no one.  My grade is important and there is no way I am leaving it in the hands of a classmate.  I always do all the work, and am forced to share the credit.  All I have learned from these projects is that people in general are unreliable, unflexible, and difficult to work with.
