I thought that the test was a lot more time consuming than the practice tests. However, one person on the test told me that about 10 questions were identical compared to the November test a year ago.
I'm also applying to top 20 schools only and was hoping for a result somewhere in the 90%+ range. I had got around 94% on each of the old practice test, but on the older test from the 80s I got 66 questions correct, but the tests have gotten harder since. However, I messed up pretty badly yesterday after being incredibly stressed. I answered around 55 questions without guessing on any of them, but I know that I answered wrong on the first question and was extremely sloppy on one other and I think I added a few fractions incorrectly in some others. I had a nightmare experience on of the problems that was converted to an integral of the form:
20 - integral = ?
However, I managed to write
20 - integral = 10 - integral
after the first equal sign and tried to redo the exercise LOTS of times and each and every time I had written the same thing down getting an answer that was off by ten and way too small. Never actually got the answer right, so left it unanswered and was totally panicked after it which messed up the rest of the test.
The battery on my watch also stopped working during the test... talk about bad luck and stupidity for not changing the batteries! NOTE TO EVERYONE ELSE: CHANGE BATTERIES ON YOUR WATCH BEFORE THE TEST!!! I'm going to take it again next month though. Just hoping that there's room at my testing location for stand by testing.
