Most people who think that the GRE is stupid and useless also have low GRE scores.
Like it or not you need good GRE (or GMAT)scores to get into a good program, because like it or not, people with good GRE scores tend (I say tend) to have natural academic abilities far beyond those of mortal men. The GRE is designed to be hard to do really well on (read 85%-90%+) without intuition, insight and reasoning skills - not just grade school math and vocabulary skills.
For the not-so-lucky end of the gene pool, there's another reason the GRE is useful to ad comms. Because you can do well on the GRE by working hard to prepare for it. So, low GRE scores mean either 1) you are not naturally gifted or 2) you didn't work hard enough at passing it and might not work hard enough in grad school. (What,you think comps don't require the same level of dedication?)
So you say "I worked really, really hard and I still got a 130Q". You might want to lower your sights(and your sites), head for the chat room, and complain about how useless the GRE is.
