My son went through this before. His project partner bought some computer codes. My son wrote his own codes. When the 2 combined, his partner's codes couldn't work. End up he had to re-write his partner's code. If he didn't do for him, both of them would fail the project.
Each time when he had group project he would look very troubled. And most of the time he got lousy partners. I think it is the university intention so that the lousy one could learn from a better student.
