You have strong stats and extracurricular activities that align with your STEM interest, which is beneficial. When I applied last year, Vanderbilt only had 1 supplement about an extracurricular activity or work position, but you’ll be required to submit additional essay(s) if you apply for one of the full tuition scholarships. I’d recommend interviewing as well; the form to request an interview should be accessible via your MyAppVU portal.
If Vanderbilt is your top choice, I would strongly recommend applying ED, as long as you can afford it (Vanderbilt FA is extremely strong, but don’t count on receiving a merit scholarship-----if you’d require one to attend, apply RD not ED.)
