What is Early decision ?
Early decision meaning A plan that allows students to apply and be notified of an admission decision (and financial aid offer, if applicable) well in advance of the regular notification date. Applicants agree to accept an offer of admission and, if admitted, to withdraw their applications from other colleges. There are three possible decisions in response to such an application: admitted, denied, or not admitted but forwarded for consideration with the regular applicant pool, without prejudice.
