<p>I think the op is applying to more than one school. </p>
<p>“Early Decision candidates may only apply to their first choice college at Carnegie Mellon. Additional colleges may be added for consideration during Regular Decision for those Early Decision candidates not offered admission.”</p>
<p>If you are applying to CFA and regular decision to another school you should apply by the earliest deadline.</p>
<p>So if I’m doing regular decision, I should check that one even though it says Jan. 1st? Because CFA is due on December 1st, but the Dec. 1st option is listed as EDII.</p>
