College or Six-form??Watch
Although having a social life is great, it’s not the priority. After all, there may be new external students coming in to the sixth form that you can become friends with. I certainly know that that was the case in my sixth form. Even if not, there are plenty of other ways to meet people online or in public. Also, if you don’t really like your friends, there’s nothing wrong with going solo, for now at least. Just remember what you want to study is what should make your mind up. Just make sure you’ve visited both and had a look at their courses. Good luck!
