Try to be yourself and don't get to the wave of arguing with parents. You really shouldn't smoke at the yard or excersices even worse, 'cause it's real dame bad thing. Speaking of learning. Do not get upset if you ave problems with anything. Go and get help, but NOT from your classmates as in my expirience they might do it evem worse. You should remember what you study for only one person-- you.
Speaking of elder ones-- I'm not so expirienst.

Schoolchildren can make their school life better by the way of aspiration to perfection of their knowlege. They will get good grades. If they want to be active and pepful on lessons, they must go to bed early and do their homework in time. We can say, that they must make friends with the others in their class. It will be easier to do hard work.
