well, it looks like you guys are getting well prepared for the exam, and one of the best things you can do for yourself is try to be relaxed when you sit down for the test. I did not see one person pull out a newspaper to read before the exam as Lindeborg suggests, but I was relaxed going in, or certainly after reading thru a few problems.
I had to come up with an engineering solution that was not on the test, but was critical to my success I feel. This may be more appropriate for a Fudgey thread, but here it goes:
There was a person sitting in front of me with the most foul odor eminating from... well I'll spare the details on that.
The odor was pervasive and distracting, and I might have started to get nauseous except for my improvised solution. I took two tic tacks and held them between my index and middle finger of my left hand, nostril width spacing. I then held my fist under my nose and enjoyed the added benefit of minty smelling salts for mental clarity as well as masking the emissions of the offender.
I did not notice anyone else passing out form the odor, but my nose was approximatly three feet from the source, and I had little dispersive relief.
Good luck guys, have a turkey dinner the night before to help you sleep!
