You want to know what annoys me? When teachers don't post grades. My Search for Faith teacher hasn't posted grades all semester. I just finished my final, and I have no idea if I'm even passing the class! Of course I'm a good student, but I sincerely care to know my grades.
My advice to you all, if you're looking to pick class, use ratemyprofessor.com because the website will give you points on grades and stuff. Especially if you want a teacher who grades ASAP!
I'll try to cool down before my next final...
