You can't ask for more draft paper in the examination room. The invigilator must ensure that each candidate has only one draft paper. In fact, one is enough, just know how to use it. You can use a pencil to calculate, use this one and then use an oil pen to calculate, then use a black gel pen and finally use red. If it is not enough, replace the draft paper you use with the invigilator's, and make sure that the draft paper is complete. . . . Paintings and tokens must be painted in black. .
