Dear Editor,
I’m a Senior 3 student. I failed the mid-term examination two months ago, which makes me very sad. If I can’t do well in the examinations now, my dream to enter one of the top universities next year will not come true. What is worse, I find I can’t study as hard as before and easily feel tired. I also feel very lonely now. My classmates are all busy with their studies. I miss the days in Senior 1 and Senior 2 when I could share my happiness and sadness with my classmates.
Yours,
Grace
