We students enjoy our school life, but sometimes we feel unhappy.It’s every student’s       dream. At the       of every term, we have six exams.

Last week, I finished my final exams. The math exam was the easiest one of all. Most of the problems were from early exams,so I       it soon. The biology exam was hard. The questions were so difficult       I had to guess the answers to them. And there wasn’t enough       to check every answer. But after the exam, my teacher said I did well in it.

In the computer exam, we had a lot to do. I thought I needed more time, but some of my classmates didn’t think      . They just wrote down the answers quickly and then       games.I didn’t think I could get a good mark in the English exam because it was a little difficult       me and I didn’t work hard enough at English.

In our school, we can       some elective courses (选修课). That means students can learn these courses by       and then take the exam. If they pass, they don’t have to have these courses any more.

Now, I am very glad that all the exams are over. The summer holiday is coming and I will enjoy it.
