Sad and Worried Posted： （2 days ago）

My problem     I've been very sad these days.As a Grade 9 student，I'll have the high school entrance examinations（中考） soon.But yesterday，I failed my math test again although I tried my best.Can you provide at least two great ways to improve my math grades quickly？And because of my poor math grades，some of my best friends even laughed at me.That made me really angry，but I don't want to lose our friendship.What should I do？
