Hey man. I get the worry, but you need to understand what Ivy Leagues are looking for. They’re not looking for an excellent student (that definitely helps though) that does whatever grants them the best chance of success in the eyes of the Ivy League admissions. They’re looking for an individualistic student who looks like they’ll lead and innovate in their choice of profession. If one is planning on becoming a doctor, extracurriculars such as a medical internship, a biomedical club, and others would be great. You need to demonstrate an invested interest and leadership in your future profession. So what do you want to show ivy leagues you excel and will innovate in?
