I'm going to take my friends names off our group project
Why would you remove your friend's name from a group project?
he hasn't helped us.
If you are assigned a group project, they should also be responsible for helping out as well. You should try getting a teacher to talk to them and see why they aren't contributing to your group project.
Nah, I'm going to deal with it on my own.
If you have to be on a team you need to work as a team. If you remove them won't the teacher ask you about it? Simply approach them as a concerned group and ask them to lend a hand.
