Hi! I was wondering if you guys could offer some advice:
I applied to a highly competitive Early Action school, and today, when rereading my common application, I realized that I made very, very big mistakes. I misrepresented my activities (saying I participated in them for 5 hours/week instead of 30 hours/week!!!). And also, I made the same mistake with the timing for other activities AND in my additional attachment! I'm so worried

Does anyone know what to do / if the colleges will could that against you? I know that I HAVE to correct it at least some way because the activity plays a large role in my application.
Should I call the Admin office? Email them? Any advice in general?
Thanks!
