<p>i have to be honest, but ACT of 27 or even 30 is subpar for S, much more for ED. Applying ED or RD is really case-to-case decision and strategy as well. After much evaluation & research, my son & we figured out that it would be a tougher call for him to apply ED and have better chances on RD. He has a ACT of 33 & SAT of 2200+, 11 AP classes and outstanding ECs. He was lucky enough to make it. His classmates with 2400/36, 10+ APs & outstanding ECs applied ED and made it as well. Note that it is not enough that one has many APs - AP score matters. Check the other threads to see how you match up. Your ECs need a lot more boost as well.</p>
