i hate my group project team

so our prof split us into random groups for a project and i got paired up with these two total opposite people. one is this super overachiever who’s like always talking about how we need to be perfect, which is honestly so not necessary. the other is chill af but also totally unreliable, always making excuses why they can’t do their part. i’m trying my best to keep things afloat but it feels impossible and i end up doing most of the work anyway. worst group ever.
