There are many reasons why this is an absolutely terrible idea. I think it could actually keep you from getting into your desired schools.
1. Your score will not count in the mind of Adcoms b/c you skipped the AWA. The GMAT is a marathon, if you choose not to do the AWA you basically cheated.
2. The Adcoms will question your drive and common sense. This is unethical, and will most likely raise a HUGE red flag to Adcoms.
3. This question has come up before, and all professional admission consultants would 100% advise against it.
4. Many people actually site the AWA as improving their score. This is because the AWA section allows them to settle into the test and warm up their brain. If you write 2 great essays it can actually boost your confidence going into the test.
If you'd like to give less thought to the AWA, you should come in with a set format and template. Spend 15 min on each essay, and score a 4.0+. A 4.0 is considered generally acceptable, anything less could litterally keep you out of schools b/c they will question if you wrote your essays and if you have the ability to write in English. Not only that, but Adcoms have the ability to read your AWA essays if they choose to do so. If they see a 0, I'm sure they'd choose to see them, and would see that you wrote NOTHING. Bad idea.
DO NOT SKIP THE AWA EVER! It could litterally be the choice that keeps you out of every school you apply to. It looks terrible, and will make Adcoms question you judgement, decission making ability, motivation, ethics, achademic ability, etc... Every important characteristic in an MBA hopeful. What better way to tell an Adcom that you are a corner cutter.
