How to take the Nanjing Art Test?

Sketch and color have to be tested, and now I am in a hurry to learn. One of my classmates didn't pick up the brush until one week before the exam, that is, he went to class after school, and the result was better than many who had been studying. Winning depends on what kind of prize it is. Generally, schools only look at grades. If it is not a grand prize, it may not work.
