Chongqing is also marking papers online this year. The teacher didn't say that transparent bags must be used at that time, but as you said, you must draw with a pencil first, and then use a gel pen, just in case. You know it's very troublesome to apply for a patch. By the time you apply, you may have finished the exam. By the way, if time permits, try to draft other questions on paper and then write them down carefully on the answer sheet. I wish you and I both good luck in the exam! (Please adopt ~ ~ ~)
