How can I ease a sore throat ?

I'm 14 and i've had a cold for the fast few days (since thursday night). I'm over actually feeling sick and weak and all that jazz, but I still have a really sore throat. I have to go to school tomorrow so I can't really stay home. I've tried taking pain relievers and sucking no halls but none of those work, so I don't think medicine will help (not that i have money to go out and buy some lol). Do you know any home remedies that would help? And I mean common stuff, not random things that no one would think to buy unless they specifically needed it.
