Grades Lowering!?

okay, so we all know that its hard to keep up with your grades, sports, and friends. All you have to do, is learn how to balance them out. if you play any sports, volleyball, soccer, football etc. make that your second priority, make grades first, and drama last. if you see your grades lowering, and your friends want to hang out with you, tell them that you cant, you have grades to catch up on. if thy pressure you and you don't want to, say "no." and leave it at that, if they get mad at you cause you care more about grades then friends, then they are not your true friends. true friends would say "oh, i understand" or similar things to that. At the moment your friends are not important, your grades should be your top priority. If you play on a team, then for sure, try hard and bring them up, unless you wanna be benched for many games until you bring them up. Trust me, you don't want that.
ask your teachers for extra credit in the classes you are failing and try to make an effort :)
