The difficulty coefficient of the college entrance examination does not refer to the difficulty of the examination questions, but the difficulty of the candidates being admitted to famous universities. The reason why Henan has the first difficulty coefficient is because there are the most candidates in the country and too few places to be admitted to famous universities. With a fixed enrollment quota, all competitions are held in our province. Generally speaking, it is not accurate to say that Henan's high score is inaccurate, because university admission is based on candidates' ranking in the province and does not compete with other provinces. At the same time, the college entrance examination papers in many provinces are different, and the score comparison is meaningless. But in the same province as Henan, Henan's score is not the highest now, but Henan's difficulty coefficient is indeed the highest.
