Midterms start tomorrow!!?

Midterms are next week and im pretty nervous because i have 2 AP's and i can't focus. Tomorrow i have really easy ones so i can't make myself concentrate. And my little sister has her friend over and they are yelling and laughing and doing all those things that obnoxious 10 year olds like to do, so i decided to listen to music and block them out, which is not helping...Anyway...my teachers are mean and they igned homework which i would like to get out of the way now so i have more time to study. But i can't bring myself to do it because i know that it's not due for like 3 dayss...helllppppp mee
