I don't quite get the rating method of your classes/exams/whatever.
But anyway I think it's hard to resist the sweet temptation of the internet and gaming.
You should develop a certain awareness when it's gaming time and when it's real life time.
When you have your own home (no mom) this mirrors in the tidyness in cleanness of it. It's the raised finger for you.
So gather some XP and get the trait "Awareness".
