Dear Mary,
Rencently,something bad happened to me.Last month we had an examination,and my grades weren't pleasant.My math got 86 points,which made me very anxious.The senior high school entrance examination is coming,what should I do to improve my math.I have tried my best!How to study math in less than two months?I am very very worried.I hope you can give me some useful practical and helpful suggestions.Please write to me as soon as possible.Thanks very much.
