the division of the class

I know everyone has to face that .I mean everyone around the world.
Now I'm a senior school student.I'm in Grade 1 .And at the end of this semester,we had to choose whether to study liberal arts or science~ha~
I'm sure to choose science though now I'm not so good as I used to be.But I still take an great interest in science.
But the fact is that 21 students chose to study liberal arts which meant they would have to leave our class and go to a new class.Where they have to face new faces and get into the new circumstance.
Some of my best friends chose liberal arts.I was really sad about it.
At the last day,our class held a party to remember the last moment with all us together.
Our head teacher gave a speech about how brilliant the students were who would study liberal arts.She'd hardly finished when she cried loudly.All of us bursted into tears .
I hugged all of my best friends!
I'll remember the happy days we've spent together forever!Yes! Forever!
