Don't worry, I won't jump. But I do need some advice or perhaps an explanation as to why my recent prep test went so poorly.

I have been studying for about 2 1/2 months. I average around 2 hours a day/6 days a week. I haven't made an appointment for the GMAT yet since my testing center usually has openings that I can schedule only 1 - 2 weeks out.

I have taken the following practice tests:

1) GMAC Prep GMAT - 550
2) GMAC Prep GMAT - 570
3) Manhattan GMAT - 570

After these first three tests, while I did show slight improvement, I knew I wasn't getting enough out of what I was doing. Thus, I reevaluated my study method and essentially went back to the basics in the different Quant sections and I concentrated on reading the verbal section much more carefully. I also worked on my stamina. After about 1 1/2 weeks after I redid my study strategy, I scored the following:

4) Manhattan GMAT - 670

I was obviously very excited. I recognized that a 100 point jump is a big, so I knew to not completely believe that I was at the 670 level yet. However, I figured that even if I subtracted 50 points (which, I believe, is the range that Manhattan GMAT believes their tests predicts) I would still have a score above 600, and I was showing continual improvement. So, while I wasn't satisfied, I was happy.

Then I took my 5th practice test after reseting the GMAC software:

5) GMAC Prep GMAT - 480

I stared blankly at the screen. I could not believe I scored that low. I really can't explain why. I did not feel too fatigued during the test, and I felt confident for the most part.

Specifically, what I really don't understand is why the Quant section unfolded the way that it did, which I only scored a 31 on:

- I got the first 5 out of 7 questions correct.
- I then missed the next 6 out of 7, including 4 in a row. I clearly realize that is not good, however...
- I then got 18 of the final 23 questions correct.

I understand that the GMAT is scored by the difficulty level of the questions answered. However, since I did bad on only one group of questions and I got so many questions correct in a row, why didn't the test give me harder questions to give me a chance to improve my score?

I'm also wondering if anyone out there has had similar circumstances in terms of doing well on a practice test and then doing so poorly afterwards. From what I understand, the MGMAT practice tests are not easier than the GMAC practice tests, correct?

Anyways, any advice would help out! Thanks!

a string of wrong answers in the middle of the test carries more weight than a string of wrong questions at the end - to my understanding... if you get some 1/2/3 questions wrong in the beginning you can usually get back up into the upper range of difficulty if you do well on the rest of the test... but if you get a big string 6/7 wrong in the middle, there just aren't enough questions at the end to make up that ground... by then the algorithm thinks that it's got your level pegged

Not enough questions to make up that ground? I had 23 questions left, which is more than half of the test. I guess that's just the nature of the beast. If that is the case, then that leads me to believe that the first 15-20 questions are, by far and away, the most important.

Thanks for the help!

I don't know if the first 15-20 are the most important, with the situation you described, the issue was more you missing too many in a row. You never, under any circumstance, want to miss more than 2 in a row regardless of when you miss them.

It's not that the beginning is more important per se it's just that getting a long string of wrong answers is more detrimental in the middle than in the end.
