Freezing...

I am freezing in the computer lab in my school now.Today is so cold.Lucky I got my jacket back yesterday if not I don't really know how to survive today.Still got many things to do after this.Next class is at 2pm,Mechanics II. Sianz!
It is still raining outside now so many people will stay in the school.I want to do my homework but where is there place for me to do?
And just now teacher announced to the class,the test is tomorrow.Any question quickly ask ok?I was like HUH?!
