<p>Duke admitted ~32% of applicants with similar profiles last year, so I'd say you have a pretty good shot.</p>
<p>How did you come up with that stat, warblersrule?</p>
<p>Class rank, mostly. Duke considers the toughness of classes and the grades earned to be two of the six considered categories. Test scores, recommendations, ecs, and essays are the other four. The OP's ACT score sits very comfortably in Duke's middle 50% range of 30-34. </p>
<p>Top 10 of class: 32.4% admitted
Top 5% of class:32.2% admitted
Top 5-10% of class: 12.5% admitted
Top 10-20% of class: 8.59% admitted
Below top 20% of class: 3.05% admitted</p>
<p>well that's pretty much sayying i would be almost as well off, if i was ranked 5% lower?</p>
<p>Not quite. The data I listed above combines ED and RD data, and I suspect quite a few more ED applicants in the top 5% get admitted than RD applicants in the top 5%. Having a high rank and GPA will boost your application. </p>
<p>There can be a big difference in admissions with very small differences of rank. Penn, for example, admitted 38% of valedictorians and 33% of salutatorians. Brown admitted 26% of vals and sals, 20% of those ranked 3rd and 4th, and 15% of those ranked 5th.</p>
<p>No, because not all schools have have 400 seniors. In a school with 200, for example, the 5% cutoff IS the top 10.</p>
