How can i convince the principal i've changed?

hi guys, I got a refferal, 2 days o STOP and 2 days of ISAP. the assistan priciple said that there is a 99% chance I won't be going to that school for sophmore year, but if a miracle all of the sudden shos up, then he will convince the pricipal that I...

have changed and will ecuse me for this time.
Can you guys please give me advice?

wow!! ummm I think you should definately improve on your behavior and the way you try to do things.everyday in life there will be new steps we must take to get to the next level.just try your best and dont let anyone disstract you and stay focused.dont let anyone tell you that your not capable of being successful and to prove all the haters wrong just show them what you can do instead of telling them.because actions speak louder than words.

just do your very, very best in school.
get fab. grades, all A's.
no tardies.
never get in trouble ever again.
when you see a teacher, assis. principal, or principal, say hi and hows it going, just casual conversation.
be friendly with all students, even your enemies and if you they or you start a fight, just back away and keep walking.

thank you guys so much, but do you thnk they will accept me for next year? I mean my school is ranked 120 in the nation, oh by the way im in high school.
