I did not optimize for the GRE, I did not prep for it, I did not look at a study guide for it, I simply went and took the test cold. The questions were on material one would expect to cover in basic engineering and science courses.
I don't buy the notion that anyone who does well on the GRE is doing it with tricks and fake/useless knowledge and/or cheated.
In a sense, you're like an athlete who doesn't take steroids or doesn't push the limits of doping policy by trying to game the countermeasures, and instead of feeling aggrieved that others are achieving similar/better results as you via their just-within-the-letter-of-the-law tactics (or sometimes wildly outside the law tactics, a la Varsity Blues), instead you still feel some allegiance to an idealized view of a fair system that simply doesn't exist.
People are always looking for an edge, and entrepreneurs are always going to be trying to sell them one, whether it works or not. (Look at all the diet books out there, it's a billion dollar industry.)
> idealized view of a fair system that simply doesn't exist.
I'm not suggesting it is ideal or perfectly fair. I'm suggesting it isn't nearly as irrelevant as many argue.
For those who want to prep or game the system, why not do it right? Take the math classes, and actually learn math.
