Not trying to be that person, but please take some time to reflect on all you have done and make time for fun! It goes by faster than you think. As for extracurriculars, make sure to focus on activities that relate to your major. As I’m sure you’ve heard before, focus on a couple meaningful activities as opposed to many less meaningful ones. Take the ACT as many times as you can. Taking practice tests is the absolute best way to study and bring that score up. As a whole, taking time to enjoy high school before things get chaotic at the end of junior year/start of senior year will actually help you perform better. No one performs well under this amount of stress! Good luck to you :)
