Because horizontal arrangement is more conducive to the overall observation and comparison of the questions, vertical scribbling is easy to make students sit up and take notice, find it inconvenient to do the questions, and also prone to mistakes such as wrong answers and omissions. Horizontal drawing is convenient to find the answer area that needs to be drawn at a glance, neat and orderly, which reduces the difficulty of drawing and improves the accuracy of drawing.

Horizontal answer sheets are usually numbered on the left or above, and horizontal marking also makes the marking process more convenient and faster, which improves the marking efficiency. Therefore, it is more reasonable and scientific to paint the math answer sheet for the senior high school entrance examination horizontally.
