<p>If you're deferred ED, do you get to submit extra things you may have done in the previous two months that will help your application? Also, will they look at Senior year grades if you're deferred? Finally, do you have a better chance in RD if you went ED? Thanks...</p>
<p>princeton will see that you were deferred ED, so they know that princeton is your #1 choice...as for extra material, you can send it, but i can't promise you that the admissions staff will pay any attention to it...they may or may not...all in all, if you are deferred ED, i think you have a better chance RD with respect to the rest of the applicant pool</p>
