20 18 National College Entrance Examination: What are the main points of the inequality in selecting math problems in Volume I?
No, marking the college entrance examination is online. First, the computer recognizes the box you drew and scans every question to every teacher. Each teacher can only see the answer area where he should mark the questions. If you don't draw, the computer can't scan it at first, and it won't send your answer to the teacher. The teacher can't see your problem, so naturally he can't show it to you.
