Scoring confusion

by drolen1 » Fri Jul 03, 2009 7:18 pm
I'm taking the GMAT next Saturday (the 11th, not July 4th), and have been studying off and on the past few weeks. I really need to buckle down, but working full time and the fact that 1) I usually test pretty well, and 2) I still have 1-2 opportunities to retake the test if necessary has led me to procrastinate. :(

Anyways, I finally got around to taking one of the GMAT Prep tests, and I'm confused how I scored as high as I did, and whether it's realistic. Scaled scores were 49 and 41 for Q and V, but my total was 750. Which I feel is high with the 7 I missed in the Q section and 6 in the V.

I actually felt pretty bad after finishing the test, especially the Quantitative section since I took it after taking an afternoon nap (not the most alert mind), and have been feeling sick (sore throat started yesterday, at least I'll be better by next Friday). Heck, I was a few seconds short of finishing the Q section. I had just figured out the last question before time ran out. Just how accurate are the scores in the GMAT Prep software?

GMAT prep is always accurate unless it is taken many times( say 5 or more times) in such case the scores get skewed , due to the fact that a number of questions gets repeated, and we know the answers to them already.

The number of questions you get right or wrong doesn't matter, per se.

The GMAT is a very smart and complicated test. For example, let's say you're scoring at a very high level, ~780. When it computes your score, it can recognize that if you got an easy question wrong, it was probably a stupid mistake. Therefore, even though that question was answered incorrectly, it doesn't hurt your score that much. On the other hand, getting a hard question wrong would probably drop your score more.

Here's a good example. During my first GMATPrep, I got 50 on quant with 6 mistakes. On m second, I got 50 on quant with 9 mistakes. When I looked back at the mistakes I made, there were a couple "stupid mistakes" that I had not made on my earlier test. But, my score was the same.

Also, two scores of x percentile are going to result in a score with a higher percentile. This is because it is rarer for a test taker to receive two high scores than to receive a high score in one section and a low score in the other. So, even though 49Q = 88th percentile and 41V = 92nd percentile, 750 = 98th percentile because it is much less likely that a test taker to receive two high scores than just one high score. Because you received two high scores, your overall percentile was be much higher than the average.

Finally -- in my own experience, it can be good to feel bad about the test; it means you were challenged, which is exactly what you want. There's no use in trying to guess how you're doing during the test; but, a high score = hard questions, which usually = feeling challenged. You need to go into the test confident, but expecting and ready for a challenge.

Overall, if you look around here, to the extent that your testing conditions simulate the test center's, GMATPrep is a pretty reliable indicator of test-day performance. It sounds like, if anything, your conditions were worse. What's important is making sure you are psychologically prepared for the actual test. I would see if you're making any systematic errors on verbal, correct them, and then get better for the test.

Hopefully this helps!
