When you have mostly essay exams that are expected to be 5+ pages in length, you have to book it!
I remember only having 2 1/4 hours for the written portion of my MA exam. I still have a copy of it and my answers. I filled out one complete blue book and got a few pages into the next in that time, just to answer three questions! If I were bored enough, I could transcribe the answers
I did once have 4 hours to finish an exam, but that one was a real bitch, and I'll try to forget the horrors of a grad school take-home exam that was 10 typewritten pages for a couple of questions.
