If I'm not paying attention, that's my problem. I hardly ever pay full attention in class. 99.9% of the time, any group work you have has nothing to do with the lectures, it has everything to do outside research. So, InstantClubHit, your shitty partners will be shitty regardless of their in-class attention level. Stop whining.
And I go to class because a) mandatory attendance, and b) checking social media or whatever doesn't mean I can't EVER pay ANY attention.
