Northwestern Admission Class of 2023

Hi I applied early decision to Northwestern and want to know what you think my chances are of getting in. Here is what consists of my application:
CommonApp essay- about my experience being featured in Seventeen Magazine
Supplemental- Strong case on why I should be admitted
I have 300+ of community service, president of a club, commited to my clubs since 9th grade, work part time, and grew up in a dysfunctional family. I have a novel coming out next year and work internships along with taking 12 AP classes throughout high school.
I have a 5.18 GPA but I am a terrible test taker hence my 1240 on the SAT. The only problem I see with my application is my SAT test score. Will my SAT score stop me from getting in? The lady doing my interview said it won’t be a big problem. But Northwestern being highly selective… It feels like a major issue. Please tell me your thoughts

the NU admissions counselor said 1240 is not problem or the alumni interviewer? It’s tough to do chance me threads these days, but what’s your uw gpa, any hooks? Good luck, you’ll know soon enough right.
