You definitely have the test scores and GPA to be in the top level of applicants with any school (although I wouldn’t report your 3 on CSA. It could be potentially counted against you and if it was self-studied they won’t have to know you ever took it). I think you would be a great fit for Northwestern - they highly value being great at multiple extracurriculars. As for Notre Dame and Georgetown, both place a greater emphasis on service and character. I would definitely focus on any projects you did for your local community board and describe how they shaped you for your essays. I’m not quite as familiar with Vandy, USC, or UVA. Overall, amazing job with your academics! I would just suggest finding a way to connect some of your extracurriculars, as they show great leadership but they aren’t as focused as many top universities look for (with the exception of Northwestern).
