Can see imagine how many test papers are here? Well, I have total of 12 classes. 50 students per class. You can see 50 x 12 = 600. Yes, it is 600 test papers for my class only to grade. I have to finish it in two days. Is that possible? Yes, it is possible because I made only 20 question, 2 points each question and everything is multiple choice questions. So it should be easy for me to grade ABC's or BBC's. After two days, I grade them all.
