What should I submit if I was waitlisted?

<p>Any tips on what kind of tips I should hit on the letter to the admissions committee? I'm already submitting several new recommendations and a more detailed resume. What are the main aspects of a student that the admissions committee is looking for in a student, aside from the general resume, good grades, good test scores, etc.</p>

<p>I realize the final question is kind of vague and general. I am aware that they are looking for how a student would make a good scientist. What I am asking is what are the best points to follow so that I can best describe my interest in science.</p>

<p>Thank you.</p>
