<p>I’m not an admissions officer or a college application expert. Take my answers with some grains of salt.</p>
<p>1) No school I know of has both an EA and an ED admissions cycle; it’s either EA or ED. However, data for EA/ED vs. RD for schools that do both rounds almost always show a higher acceptance rate for EA/ED than for RD. It can’t be said if EA has a higher acceptance rate than ED (or vice versa) because no school (at least, not one that I’m familiar with) offers both EA and ED.</p>
<p>2) Definitely not for EA, because of its non-binding nature. It’s reasonable to assume that many ED applicants don’t need FA (though, of course, you can opt out of an ED acceptance if their FA package isn’t good enough). I don’t think that FA packages for ED vs. RD would be any different, but I’m not 100% sure of that.</p>
<p>3) Many deans of admissions (including Harvard’s and Yale’s) have said this about EA/ED: that they only accept those that would 100% be accepted RD anyway. In that sense, applying EA/ED doesn’t increase your chances of acceptance. However, applying early (especially to an ED or restrictive/single-choice EA) shows some modicum of “Hey, you’re my first-choice,” which can’t hurt.</p>
<p>In that vein, I’d recommend you apply early to reach schools, assuming your stats & application are up to par. It seems many EA/ED schools, including Harvard and Yale, defer a majority of their applicants (Stanford is much more heavy-handed with the rejections, though). So, it doesn’t hurt to submit your application early to a reach school, have them defer you, and then get a second chance/second read come the RD round in the spring.</p>
<p>The early applicant pool is probably stronger. However, my take on that phenomenon is that the early applicant pool is smaller than the RD pool. The slackers, last-minute applicants, etc. all go into the RD pool, which decreases the RD pool’s overall strength. It’s my opinion, then, that the early applicant pool is stronger not because it has more strong students, but because the RD pool has more weak students.</p>
