<p>I don’t understand why you’re saying to the OP that both are unlikely to accept him and things like these when you don’t even know his stats etc. Of course, Dartmouth and Amherst are two of the toughest schools to get in, we know that, but if he wants to try ED in one of these, why not? A lot of people do ED in their dream school, both internationals and Americans, so I think OP’s intention is a great idea.</p>
<p>Anyway I suggest you ED in the school you really really like best. I know it’s kind of a meh advice, but it’s the single thing you should look at at the moment. In fact, if you apply and luckily get in then you have to attend there, so being sure of that school sounds like the most important thing to consider since both schools are amazing in each aspect. Find out where your intended major is “better taught” and look at the community that you would like to join, even the place can determine your choice at this point. If you don’t get in or you’re deferred you can always apply to the other RD then. Otherwise, if you can’t really help deciding now, then I suggest you to apply RD to both.
Personally, I suggest you Dartmouth, but it’s just my opinion. I’m an international student too and I’ll apply RD at Dartmouth :)</p>
