in the national college entrance examination in june 2018, 9.75 million people took the exam, which shows the great pressure of competition. it is a pity that many people are ruined on their way to university just because of one failure in the exam. one of the disadvantages of chinese education is that it only takes one exam to select talents. however, because there are too many references, the nation can only select talents through examinations. facts have proved that this selection method still has some merits.
