I go to a performing arts school and major in Creative Writing, I am a leader in my school’s student-run theater club, and have spent my summers working at a local Dunkin’ Donuts. I plan on taking 3 AP classes in my senior year, as there was only 1 AP class for junior students. I do not have any awards however and I do not know how else to stand out to Questbridge and to the colleges that I plan to apply to (USC, uPenn, Columbia, and Northwestern)

How much of a chance do I have? Even if you do not have a definite answer, I would love some advice on how to become a better candidate!

Make sure your essays are amazing tell a story (a true story lol)
