If you want to be successful as a quant you should be perfectly capable of solving some basic geometry and algebra II problems. The depth of knowledge required to answer them is very small, and 28-29 of the 30 are bound to be [almost] completely straight forward.
If you are perfectly capable of doing it, you should then be perfectly capable of demonstrating it. When I applied to grad schools, I did not view getting a perfect score on the quant section of the GRE as an accomplishment, but rather as a prerequisite, but I suppose that is also partly me. What is not a matter of personal taste, however, is that if you do not get an 800, you are at a substantial disadvantage to everyone else that did.
As proof of this, I cite that the 25th percentile quant GRE scores of Baruch's latest incoming MFE class is 800, with an average of 796. Take from this what you will.
Also, to contrast what has been previously said - do not take the GRE more than two or three times. Like all other standardized tests, the more you take it, the better you do. And colleges get all your scores, not just the last ones. And when they see 12 scores on that list instead of two, you can imagine this probably looks very bad.
I totally agree with you on this aspect..If one is good enough one needs to be capable of proving it... But I actually messed up in couple of fairly simple questions ..Just lost my composure a bit and knew it while giving the exam that Ive made a mess of those questions. As a result it was playin on my mind throught the remaining questions and it just was a cumulative effect that musve led to a 780 ..... I know Im good enough cause my undergraduate math grades are fairly good...And I have had exceptional grades in math throughout...I also in fact held the position of a TA in business stats...But somehow managed to mess up the one thing that counts........
anyway taking the test again is out of the question for me as of now.Im pretty squeezed for time . I guess I have to depend on the other aspects of my profile to make it up.....and hope for the best
