<p>Chances are worthless. All anyone can do is tell you whether your scores/grades are within range (they are). The rest is all based on things you can’t give us without sending us your whole app. Do your essays show your passion for math/science? Do you seem like “a Techer,” whatever that happens to mean, to the students on the adcomm? Do your teachers say something particularly interesting or impressive about you or do they write the wrong name on your rec? I think you have a “decent shot,” but what I mean by “decent shot” is that they won’t throw your app in the trash as soon as they see it. (Disclaimer: I have no evidence that they do this to <em>anyone’s</em> app).</p>
