I just took the Sept test, and my nerves played a HUGE factor in how I think I did. Since I don't normally get nervous for tests, this consideration was something I dismissed. I cancelled my score because I KNEW that I didn't perform as well as I could have. The nerves really affected me on RC (my first section, and usually my weakest) and the games (which is normally my strongest). I ended up taking way too much time on both of these sections. Also, believe it or not, all of the pencil scratching and sighing going on around me distracted me as well. To give you numbers, the last 10 PTs I did, I meaned a 167.5 with a 168 median. The last 5 I did, I meaned a 170 with a 170 median. Based on the post mordem discussion and the amount of guessing I did, I'm thinking a 165 was about what I would have scored.
A few things I'm thinking about for Dec:
1) Practice with 32 mins a section instead of 35.
2) Practice with the TV on quietly in the background, or in areas where there is random noise (ie, bookstore, coffee shop)
3) I'm focusing on raw scores as opposed to scaled scores. I think some of my practice scores were slightly inflated due to my strength in games on older tests. Now, I want to focus on missing no more than 2-3 per section.
4) Redoing questions I got wrong more. I did this, but I don't think enough. Especially in RC.
I think you can get over the nervous bug if you don't dismiss it like I did. I think that was my biggest mistake.
