Does anyone know how to change your grades on power school using a hack or something?

I need to figure out how to change my grades...not drastically of course.....just by 1 percent...and my teacher is dumb so he won%26#039;t notice....so if anyone knows and can teach me i am willing to pay....|||I think that%26#039;s illegal|||you an idiot...you know thats illegal right? im sure if you talked to him he would change it for you...btw if they found out what you did you might have to go to court...or even worst court and jail time buddy
