Ssn# Mistake

Hi Guys! This was an honest mistake. I applied for a local community college with what i thought was my social security number. But it turns out i was off by one number, so i have been using someone else's ssn on accident. Im scared to call the school and tell them my real social because then they might start charging me out of state fees, which i truly cannot afford right now. is it really important to give the real social security number? like does my name tie into my number and grades? i'm not sure what to do. and i'd love any opinions thank you!

i suggest you call your school pronto and give them your real SSS and if you don't it might bight your ass in the end
