It is now common knowledge that the College Entrance Examination is held on June 6 and 7 annually, as a national policy , during which，seven different subjects are tested depending on what you learn, science or art.

For me, Chinese, Math, English, Politics, History and Geography are included. Due to its great importance, every student in China would do his best to get ready for it, and I am no exception.

I spent a whole year reviewing all the subjects carefully until I thought I was fully prepared. Eventually, the day came. Nervous at first, but I did give the best form I could have (am now in the best form I have had) in years.

Frankly speaking, the papers were (are) not so hard for me despite some difficulty. Consequently, I have every right to believe that I shall be very likely to be admitted to my dreaming university. Just wish me good luck. Looking forward to your reply. Best wishes.
