Going to get jumped tomorrow at high school?

I know this sounds ridiculous but in cl this kid tried cheating off my test and wanted me to show it up close becasue he apparently doesnt have 20/20 perfect vision and i didnt respond nor did i give him room to see...and I ignored him even after the test and he said after cl "watch out..me and my boys going to show you how to respect *****" ..His exact words left me as he knotices no face expression on my face..im a silent guy and alot of guys doesnt liek me because a number of girls like me for their reasons...and no body knows im currently trained for jeet kune do..which is a style made by bruce lee also known to be a "free fighting art" and I dont want to actualy use it on them...I havent gone that far into training and might injure them far from my intent sence i wasnt able to control and maintain force as much...what should I do? I dont want to tell..becasue i dont want to get into conferences or future fights in result..I have no time for this pathetic crap.
