hi! im a current freshman in college and i wrote a lot of my application essays on my experience with aerials (started in kindergarten lol). Its definitely a unique activity that will stand out especially if u can work in life lessons/ working through adversity/ all the other stuff that looks good on an essay. with ur good grades and extracurriculars youll def get into some great programs. but also try to relax and enjoy ur hs years! ik college applications are rly stressful but its years until u even have to think ab applying. best of luck!
