<p>You can only apply to one school under ED. But you can apply to multiple schools under Early Action, except for those who have single choice programs, such as Stanford, Yale, and Boston College.
Special circumstances:
- 1ED + multiple EA’s: for example, you could also apply to Penn ED, MIT EA, and Caltech EA at the same time, if all of them give you acceptance letters, you can only attend Penn, yet not MIT or Caltech, since Penn ED is binding while MIT and Caltech EA’s are not.
2)As mentioned above, you only apply to either Stanford or Yale for EA programs. But this time you can’t apply to an ED school, Penn, for example, in the meantime.</p>
<p>Hope that would help.</p>
