My practice tests had been in the range of 163-167. I took the test, completely panicked on the first section and actually had time issues that I had NEVER had before on two of the sections. I completely forgot every game strategy that I had painstakingly learned and ended up staring at two of the games like an idiot for at least five minutes apiece, then guessing (and not guessing too brilliantly either - I should have found the fact that I did not get a single "A" suspicious
) I agonized for nine days over whether or not to cancel my score, and then for the next two weeks was sure I had made the wrong decision. I ended up with a 161 which was better than the sub 155 (or even 150) score I was anticipating, but I know I could have been in my range if I hadn't let nerves get the better of me. Anyway, point being I think nerves probably affect a lot of people who end up dropping and I'm not sure of any specific techniques, but learning how to stay cool and collected is more important than I thought (because I foolishly thought, that's how I normally am, why should the morning of Dec 5 be different from any other morning...IT IS), so keep that it mind. Good luck!
