Ugh, I'd say, it sucks having a class where pretty much every other guy but you has pretty much decided to walk out of it (as in, they are no longer going to attend). Admitedly, they have no chances to pass which is why they're doing it; but still, that's not a reason to pretty much leave me alone in there. Considering the work at this point is now stuff to be done in teams. Well, the whole class is a single team.
Worst of all, they don't even want to tell the teacher about it! They just plan to no longer attend the class or even explain so. I'd feel more frustrated about it if it wasn't that they are pouring effot into the other classes, which also have class-wide work to do.
Man, it's too stressful... at least it's the last classes of my career...
