Yes, usafa currently looks at math and reading. I would focus there. A word of caution though...the one constant at the academy is change. So you never know when a policy will change. A good example is the University of California system. Up through 2009, they only looked at math and reading. AFTER the relevant testing period (for the 2010 grads), the UC system decided to look at the writing scores too. That was a very unpleasant surprise for the kids who didn't apply themselves to that section of the test. My advice is to concentrate on your math and reading, but still give the writing section a decent effort. Good luck.
