im looking to get into a 20- 40 ranked school, I have the gpa (3.9) and the math background for it, should i retake the gre knowing that i will do better (according to the practice tests), or do i suck it up with the 750 and apply anyways

Personally, I would recommend taking it again in a month or two. I think you should still have time to retake it before apps are due.

Suck it up and buy the Kaplan GRE study guide or another study guide and go through the Quantitative Section.

It seems unlikely to me that you can't get a better score, but it is just a matter of remembering the stupid formulas that they want you to have at the tip of your fingers.

Also, remember because it is an adaptive test the first 10 questions are so are much more important than the last 10, so spend extra time on those.

It depends on other factors...I would say.

I only got a 760 and got into schools in the 20-40 range. I had plenty of previous research experience before, though.

Think about it this way...do you think 20 more points on the GRE will get you into a program you wouldn't have gotten in with a 750?

I don't think it can hurt to take it again, but at the same time, a 750 is not the end of the world as long as the rest of your application is strong. I earned a 750, and I think I did pretty well admissionwise (4/8 top 20 schools). I am by no means an expert on the process, but from my experience, it is more important to have glowing recommendations and a strong transcript. Best of luck with everything.

The thing is you can't change much of your application at this stage. So even if the GRE is not that important is basically the only degree of freedom you have left. Sleep less, practice a couple of weeks and get a 780q. THen again if your profile is strong and your ambitions light, theres no need I guess.

Sleep less?

GRA math is more of a random luck than a strict math test, i suppose (with regard to range 750-800).
i don't see huge differences in the quant abilities of people scored from 750 - 800. Just be prepared and pray. good luck,

Someone else has mentioned this here before, but here it is again:

The standard errors for the GRE are quite large. This (http://www.ets.org/Media/Tests/GRE/pdf/994994.pdf) is the technical reference document. Page 12, the footnote to table 6, notes that if you want to compare two scores to see if the student's abilities are truly different, you have to do a few things...

1. Each score level has a standard error conditional on that level (CSEM). Take the highest of these two SE's.

2. Multiply that by 1.65

3. If the score difference is greater than that value, then the difference in true ability is significant at the 90% confidence level.

For the quantitative exam, they only give CSEM for 750 as 28 and 800 as 9 (bottom of page 20). They don't give the CSEM for 760-790.

Hence to compare someone with an 800 and someone with a 750:

28*1.65=46.2 < 50 = 800-750.

So the abilities are different...but only at a 90% confidence level. Surely the comparison of a 760 with a 800 is nonsignificant and similarly 750 with 790, or any combination of scores in between. If we use the more standard 95% confidence level, even a 750 and an 800 may look the same.

I can only hope admissions committees, who know how important variation in measurement is, consider these details when making decisions.

interesting, but i don't think most adcoms are aware of this
