<p>^considering that last year the overall acceptance rate was about 8-9%, that this year there have been a record number of applications EA (and probably RD), the EA acceptance rate was about 11%, and that matriculation rate in the 2018 EA pool is high (I can confirm this, most kids in the facebook group seem pretty committed), RD kids can be looking at a really low acceptance rate of 5-6%. Assuming that Deferred acceptance rate remains the same, deferred applicants may have a boost here. </p>
