<p>Mac, I don’t understand what you mean by ‘slots opening up’. The number of available RD openings at YPS is the total number of applicants each school plans to admit, less the number that were admitted EA/ED. If a Harvard EA admit withdraws his ap at Yale, all that means is that there is one less competitive applicant in the pool. Getting into one (HYPS) hardly means you’re a shoo-in at the rest.</p>
