They don't care much unless you get a score that calls into question your basic reading/writing abilities. What you are suggesting is just plain stupid. Write the essays, it's not that hard. I didn't even know the format of them when I went into the test, but having taken standardized tests in high school, I was fine.
Also, as someone who has majored in physics, it shouldn't be hard at all to get a good quantitative score since you should know most of the material cold. Sure there are some things you haven't used since high school but those are very easy to relearn. A large portion of the test is ridiculously easy. I'm talking about basic algebra and reading charts.
