Send a draft paper for college entrance examination mathematics. If it's not enough, you can ask for it again. You need to hand in the used draft paper when you want it again.

When handing in papers, you can only leave the examination room with your admission ticket, ID card and stationery. But you can't take the draft paper, test paper and answer sheet out of the examination room. Be careful not to take out the draft paper when handing in the paper, otherwise it will be treated as cheating.
