APs= AP world=5 This year= AP Lang Ap Calc AB AP Chem Next Year= AP Lit AP Calc BC AP Bio AP Micro AP Macro
EC: Beta Club, NHS, NHS in Science, NHS in Spanish, Varsity Cross Country, Varsity Track, Varsity Math Team, Instructables Club (Co-founder and officer), Medical Society, Volunteer at a local hospital, Volunteer at a local charity (President of Junior Executive Committee at the charity; led committee in organizing annual easter egg hunt for more than 150 Foster Children for 3 years in a row)

What should I do to improve my chances?</p>

<p>You have already done a good job on those aspects of your application which would be hard to improve at this point.
If Dartmouth is your top choice, apply ED.
Taking the SAT a 2nd time in October wouldn’t hurt.
Work on your essay(s) over the summer.</p>

<p>The only thing ‘bad’ about your application is your rank… Try to make the top 10 percent and I think you’re a competitive candidate for Dartmouth… And of course, write amazing essays :)</p>
