Just needing a little clarity on this whole 'college' experience. (Sorry, I know a lot of this has been answered in other posts, I'd just prefer some personalised advice.)
So, erm. I'll start with this; I haven't spoken to a friend nor left my house for a social meeting since the day I broke up for the summer holidays, which means I'll be starting from scratch; it's unlikely I'll meet any old friends in the classes I'll be taking, when in college.
I'm not completely socially incompetent (Evidence suggests otherwise, eh?

) but I'm wondering if there's nearly always a social circle for any 'class' (Nerds, jocks, non-stereotypical groups etc.) of people, or if it's more likely that I'd meet up with new people and that we'll all come together to form our own sort of social 'group'. (God knows what that'd be, if we're all similar)
Also, just go to any ol' party, regardless of the fact that I've never been to one? Would it be best to wait until I could go with a friend, or go anyway? Also, what's the general 'activity' in a party, assuming there's alcohol. I've never really understood.. Do you meet a stranger, talk to them while drinking..? And about what, exactly? General everyday stuff such as the courses they'd be taking etc.? I can't see that fitting the situation well

"So what's your main interest?" "Shee that gurl dere..? I to-ally fucked her." "So.. you're here for sex education..?"
I suppose I should turn up a little later, once people have gotten at least tipsy, get drunk meself and 'go with it'?
What to do during lunch breaks? Go to a .. Fff. 'Specified social area': where ya'd all just group together the first time and split off when you meet someone you click with, or would it be best to wait it out in my classes until I find someone I befriend and then 'tag along' (Not in a creepy, irritating way ;P But how else can it be said) as they hang out with their own group of friends?
Any other general tips? (Excluding the obvious 'Throw myself into all opportunities', 'join a club, regardless', and 'be myself'.)
Edit: In return for advice, I shall link you a funny photo.
