MY fight is tommorow what to do?

Try to talk your way out. If that dosent work, knee the guy in the groin, he will drop right away.
Remember, it's better to have your health than to get the crap knocked of you to prove yourself to a bunch of people(most likely highschool classmates) that you will likely not see to much of or care about their opinions.
Good luck

Well first you can stop Typing Like This.

Try to talk your way out. But dont punk out either. If they hit your or make the first punch first then u go for an attack. heres what you can do if you get into it

1) Keep ur hands up
2) Make sure u hit their face
3) Pray
4) Good Luck :D

Obviously like everyone else said you should try to talk your way out. If that fails the best place to strike someone for beginners are kick to the legs if you're keeping it "fair" aim for the ankle and knees. If your opponent can't walk he/she can't fight

Don't fight. There is no reason to fight anyone . You should only hurt someone else if they hurt you first. Otherwise just don't risk your life on someone who you don't care about.

then don't, don't risk urself in doing that.
