I'm a grad student and have been assigned to a group with several other students. This is a semester long group that will work on various projects. From the start, this group has been a disaster. I spent two days fixing grammar mistakes in another group member's paper. Some sentences didn't make sense at all and he obviously didn't proofread it because there were mistakes such as "for the for the". Another student in the group, an international student, told the student that wrote it, "great job". This was prior to me correcting it, but the fact that he complimented him made me think that he didn't read the paper at all. Absolutely no one would think it was a great paper, purely based on how many mistakes it had.
After we submitted the corrected paper, the professor sent it back to us with several notes about how to improve it. The original author told another group member that I should fix it since there were grammar mistakes and I wrote it (corrected it). In reality, his original paper wasn't even at high school level until I fixed it.
Another time we had to give a 20 minute presentation. The rest of the group wanted to go over who would say what in 5 minutes before class. However, with some coercing, I convinced them we should review it the prior day instead.
I have to maintain a B to keep my scholarship and I feel like this group doesn't care about their own grades. They seem like they just want to coast by into graduation. Should I approach the professor about this?
