I admit I'm terribly old compared to some of you, but do you realise school is important for your future, Scone? Oh yes it might be sucky to have little free time, have to study a lot, are forced to attend school and take classes you might not like.. big deal, all of us are or were in the same boat you know. But it will enable you to persue the future you want, will enable you to get a better job, with better payments. It's an investment in the rest of your life. You can have fun with your friends for years and years to come but those few years you spend in school compared to the rest of your life deserve a little more attention then faking grades. Besides the fact you shouldn't lie to your parents anyway.
Bording school doesn't seem too bad, and you'll easily make new friends while you can still keep in contact with your old friends. If it will help you to do better in school, it's definitely worth it.
