This thread is making me feel not so confident. Like others here I felt pretty good when I left. There were only a few I didn't know and all the rest I was able to work out an answer for. Like Max Power I spent all my extra time trying to figure out ones I didn't get the first time rather than checking my answers.
I'm especially nervous because on one question that I had got an answer for I realized that the units they specified (in parentheses) were different then the units used throughout the question. Both answers were given. How many of those did I miss because I didn't check??
There's no way to tell and second guessing yourself for the next 7-10 weeks will drive you nuts. You could very well be worrying for no reason though, no sense getting worked up about it until you fail.
I don't know if my strategy ultimately worked or not (I took the MEPE)but I concentrated on each question one at a time and tried to be very very certain I was using the correct units and finding what they were actually asking for in the problem statement. I skipped hard or long problems entirely and left them until the end. This allowed me to be very confident of those problems I actually worked out a numerical answer for because I was conscious of the unit trickery. I'm not second guessing any of my answers for that reason. My doubt comes from the large number of problems I had left over at the end. I worked right up till the "buzzer" in the morning and the afternoon and I had to guess on a lot more questions than I wanted to because I was running out of time.
Just going from my fuzzy, blurred, soup brain memory, I can only be "sure" of about 40 answers. That leaves a ton of room for error on the other half of the exam. Some of that other half I'm fairly sure about, but a bunch of them were just educated guesses, especially the non-quantitative questions.
When I took the practice exam, I flew through it and felt pretty damn confident. Then I graded it. (failed) I missed many problems because I was working too fast, not reading the problems thoroughly, and jumped on the first answer I got on the calculator screen just because it was one of the choices. In hindsight, I may very well have overcompensated for that during the real exam and might have taken too much time.
My only advice is to try your best to find something else to concentrate on until the results come in. Worrying isn't going to do you any good, even though I know it's hard to put the test in the back of your mind somehow. For me, the best thing mentally was to just assume I failed and prepare to take it again in April. That way, when I get a passing letter in Dec. or Jan. it'll be that much sweeter.
:dunno:
