As a Grade 3 senior high student, it's a tragedy that I am probably at school then

That's quite a sad story...

And when does your new semester starts? Seems you are in a boarding school.

回復 @啊啊是誰都對：Well, my school recalls us Grade 3 students for study in the summer vacation.

回復 @lizhenxuan：In the name of voluntary self study？

回復 @啊啊是誰都對：Yes,  something like this.  I will leave for my school tomorrow.  I will stay at school for 5 days and 1 day off.  But there is going to be a exam about one week later so I am not sure whether I will be at home at anniversary day. 

回復 @lizhenxuan：That's a sad story. But don't worry, the anniversary bash can last about one week (estimated)
