I am a middle school student,and I am addicted to OSU when I meet this game maybe two weeks ago and I find this game is so amazing and it effects my studying.It 's a really serious problem because now I am stressed about my score:I got all A last year but I think I 'll get B or C this time.But it is too hard for me to keep away from OSU eventhough I know how serious it is.Can somebody give me some advice ?
