75 minutes is PLENTY of time. I finished my first pass with over half an hour to go... and I didn't rush. Here was my strategy:
Go through and answer the easy ones, mark the longer ones (1 hour left)
Read the longer ones CAREFULLY, answer at your leisure (30 mins left)
One more time through to check for dumb mistakes
I got an 89, and felt the exam was fair.
Good Luck,
