<p>cornell and columbia would be reaches, but not undoable. your sat score is actually going to hurt you in admissions, because it’s a tad low. Also, you are lacking strong ECs and meaningful awards, and i think at this point there is nothing more you can do (as a junior, just joining clubs senior year will not look good on an app, and may actually hurt you, b/c it will look as if you are just joining them for the sake of being in more clubs). Try to work on getting more awards, or doing something over the summer regarding your prospective major.
Based on your high psat scores try to apply to some good schools that offer scholarships for NMF.
