Be sure to be a cool HS teacher like I had. He let me sleep in class, play my ds, and he was into stuff* I was into. Also I always Aced his quizzes/tests. He said my only problem was I didn't do classwork or homework.
*As in FPS and RTS
He was also a history teacher. He was the best teacher I've ever had. I even brought him an Oreo Cake for his B-day.
I miss those days... ;_;
Anyway, good luck. And be sure to stay away from the freshmen girl you lolicon.
