Dear Professor V:
THANK YOU for making it an open-book exam. I can never figure out what you think is important to know, so maybe if I study EVERYTHING we went over, I'll have a chance to pass.
On a less grateful note, why must you give us both a final exam AND a final project? Not even Professor M. did that.
Dear Inventor of Post-It Notes:
You are awesome, and if I pass my Analysis of Algorithms exam, it'll be because of you.
STOP WITH THE RAIN ALREADY.
