Remeber you are not graded against the exam - only against your classmates.
I got done taking my first law school final this afternoon. It was a four hour, four question, 300 point torts exam covering intentional torts, negligence, and strict liability. I'm starting to worry now, however, because I didn't even have time to get to the last question. Granted, the last question was worth only 30 points but that's still 10% of the entire test (which is the difference between one whole letter grade). Someone please smack me in the back of the head and tell me I'll be okay. I need a little reassurance here...
