Im kind of interested by what kind of things im gonna find annoying next year when i am thrown in with a mostly all new group of students now that we dont have sections anymore.

Have you been annoyed this summer?  I find certain people's voices annoying, but that's not specific to law school.  I think our summer classes provided way fewer opportunities to be irritated than my 1L classes did, but maybe that's a function of summer, or of me personally being more relaxed.

Raising your hand 4 times per class session and starting every comment with "I just want to be sure I have this right..."  (and then repeating what the professor just said).

Bringing cans of Dr. Pepper to class after you've spilled them twice and been asked not to bring them any more.

EATING IN CLASS.  Especially if you put the granola bar under the desk like nobody can hear the crinkle crinkle, when you sit in the middle of the front row.

go to bars with people but dont drink.

Why is that so irritating?

Was that outline so-and-so sent me intentionally wrong, or is he just stupid? 

Some dissents are important -- think Harlan in Plessy. 

That said, I don't really know the answer to your question -- we didn't have essays taht asked about specific cases or dissents on the final.
