Get Laid Tips

I am a sophomore in an all boys school and the guys are all bragging about having girl friends but I cant seem to even be able to meet a girl. The only girls that I could possibly talk to are on my bus bu any advice how to talk to and meet some girls?
they have dances i have been to 3 of them and there are about 3 girls to 1 guy but im too shy to go up to them, thank you for the help and the funny comments
