Is this really my last chance?

Ok so i'm in high school w/e drive a beater i'm 17. I was warned from the police in a meeting about reckless driving after i was reported by an old lady for doing drifts on the snow in the school parking lot. She said she felt threatened and scared ok then. The car doesn't even have an ebrake but w/e. The cop said if i was reported again they would press charges and i would lose my license for 9 months. So today at school parking lot during lunch hour I had a two four in the trunk and was showing it off. I pulled one quick drift before i left and guess what. Vice principle and janitor come out wave me down and tell me how its dangerous ya da ya da how i've already been talked to by the police. Whos beer is that? lied and said it was my 18 year old penger. He even asked if it was open. which it wasn't. He says next time i pull that in the school parking lot hes phoning the police and he said i'm gonna get arrested. I think this is getting serious now.
