Advice for life:
Stay away from drugs and cigarettes. Especially cigarettes, they may be legal, but they're horrific.
Drink can be fun, don't over-do it. Get drunk if you feel like it, but not all the time.
Take the opportunities with girls. You'll regret not doing so if you don't. If you're not sure, try, and if you get knocked back don't let that put you off next time/with the next girl. Use protection until you know it's 'safe' to go bareback. (You'll KNOW when.)
Work hard in years 10, 11 12 and 13. Enjoy school until then. (And even during these years!)
Pick a worthwhile degree and work hard at it (if you decide to do one) unless your parents are LOADED and will keep you forever.
Stay in touch with your mates when you go your separate ways. You'll see them again after uni. They might not be there when you're away and they won't be when you get back if you don't stay in touch.
Don't spend beyond your means. (I learned the HARD way!)
This is the advice I'd give my 12 year old self.
Oh, and don't worry one bit about moving up a year. All your mates will be with you!
