DONT SKIP THE AWA... it would be a dumb move... There is no better way to show the adcoms that you are lazy. Your GMAT score will not count if you don't do the AWA in the eyes of the Adcoms b/c you just blew past 1 hour of work. The GMAT is a grind, and if you can't hack it, then you shouldn't take it.
Using a loophole to try to raise your score shows bad ethics, and bad business school principals. You think they want someone that cuts corners in life? Trust me, take the AWA. I have seen this question come up MANY times, and every professional would tell you that you're crazy for not doing the AWA. Plus, many people actually say it helps them calm their nerves before they start the test.
It would be smarter to take 10-15 minutes on each essay, score a 4.5 or 5, and then move onto the test. COme in with a template, and atleast give them a try. This way you cut come time out, but you still get a reasonable a score. An AWA score of 0 would look terrible and raise red flags about your common sense.
