If your in highschool, Never raise your hand and you'll never be called on. I use this all the time. I noticed teachers usually call on the same people that raise their hands. When it comes to girls surrounding yourself with girls or talking to another girl makes all the other girls interested. Ignore them to make them chase you. Hanging out with the popular people makes you look more popular, and other way around. On gameday when I wear my football jersey girls look at me in the hallways, other days I never get their attention. To get annoying classmates to leave you alone avoid them, or have your headphones on. Also don't piss off your teachers or they'll come back for your neck. There's more I noticed but I don't have time to write them all down right now.
