What college / 6th form should i choose

Tommorow ill be choosing the college/ 6th form im going to, all of my friends and almost evreyone else from my old school bar a few people are all going to Bilborough whilst as of right now ill probably be going to Nuast if i get the grades. Nuast grades wise is a better school but theres less freedom, theres around 300 students whilst in bilborough theres around 2000. Im not 100 percente sure im ready to go to a school where ill know pretty much no one, but i know if i go to bilborough ill easily be distracted and probably wont study, im willing to sacrafice the next 2 years in order to chill in uni but at the same time am i though?
