<p>Yale is SCEA, so you wouldn’t be able to apply there and the other schools. Columbia is ED, so according to the contract, you’d have to stop applying after you got in.</p>
<p>Are you applying anywhere that offers merit-based scholarships that are not automatic for a given set of stats? Often the merit awards are not offered until well after the EA decisions are made. This was the case with my son. If he had stopped with his EA school, he would have missed the chance to use a very large merit award to a very good school.</p>
<p>Another thought: I have seen a number of students (including both of my kids) who changed their minds a bit about exactly what they wanted in a college during the course of their senior year. I think it is wiser to follow through with all of the schools that appeal to you.</p>
<p>Just apply to a couple schools that may not have early action. They may give you more money than an early action school for whatever reason, and then you can probably get more money from the early action school. The majority of my schools were early action, but I still applied for some regular- just in case.</p>
<p>CPU, some merit awards are automatic if your ACT/SAT score and/or gpa/class rank are above a certain level. Others are competitive and the number is limited, so awards are not made until after all of the RD applications are in.</p>
