There are a few things that I feel really need to be changed Such as Cornell weighing both the GRE and your GPA as 30% each. How can they count your entire 4 year performance equal to one two-hour exam is crazy to me.
I think if we stop to consider what the adcoms have to evaluate, there would be a little less GRE-hating.
Unfortunately it is very difficult (ne impossible) to evaluate the difficulty of the school and courses that make up someone's GPA. 1 person takes physics with 3 college drop-outs and gets an A, 1 takes it at IVY U that grade inflates and gets an A, 1 one takes it at Football U and gets an A. Are they the same? Was the academic rigor the same? Were the other classmates they were compared to similar? Are the grading standards the same?
There is no way to really answer these questions objectively so adcoms need some way to evaluate whether applicants are being judged roughly comparably. The GRE is a way to quasi-normalize results. Got a 4.0 but a 1050 GRE? Sorry but that is questionable next to another applicant with a 3.6 and 1400 GRE. How about that 2.9 GPA with a 1500 GRE?
Is the GRE a great test? Of course not! Is there a better one? Not that I know of..... It is an attempt to at least have some semblance of thinking how to weight a high (or low GRE). Yeah some people don't shine on standardized tests, but mostly, they will do well enough to justify their GPA if it was deserving.
Obviously neither GPA nor GRE are great predictors of Vet school success, but adcoms as a whole are actually fairly good at not excluding people because they don't fit the mold.
Look at the c/o 2014 accepted applicant thread.
There are people with low GPAs, low GREs, low experience, low/no research. Each of them got in because they do something well that the adcoms believe will lead to a successful student. No one factor is most important across the board and I think that is pretty good.
Given attrition rates pretty universally of <5%, and the success at passing the NAVLE, it's hard to argue the system is completely broken. Certainly imperfect.
And for those of you who think things should ALWAYS be done right, spend some time in a job (like trading) where success is measured in small increments above 50/50. Your ego will be smashed down pretty darn quickly when you realize how hard it is to do in a non-academic setting.
Note*** I have no particular axe to grind here as my GRE and grades were pretty comparable (especially if you ignored some miserable finance and accounting classes from 20 years ago)
