There are schools that if you don’t apply EA to certain programs, you’re not getting in - like UMD or Purdue engineering. So keep that in mind if in consideration.
If a school offers ED, in most cases it’s your best odds.
B4 you ED, make sure it’s your top choice, that you can afford the school, and that your parents are willing to pay for what it costs (not all are, even if they can afford).
