? For each single subject, the candidates in the same group in the province are sorted according to the original scores, and each candidate has a corresponding position. Calculate the percentage of the number of candidates below each original score in the total number of candidates in this group, that is, the percentage score. Then, from the percentage level of each original score, find out the corresponding score in the comparison table of standard score and percentage level of college entrance examination.

For example,

In 20 13 years, candidates of literature and history (including art) in Hainan Province were 2 1555. A candidate's written Chinese test score ranked 50th in the whole province, which was higher than that of candidates of 2 1505 in the whole province, so the percentage score of this candidate was 2 1505+0555 = 0.

"When the number of candidates is enough and the test questions can reflect the level of candidates, the score distribution of all candidates will show a bell-shaped curve of' two small ends and big middle', also known as the normal distribution curve. The standard subsystem is based on this principle. " The general recruitment staff of the Provincial Examinations Bureau said, "According to the principle of normal distribution, the standard score is between 100 and 900, and the score in the middle position is set to 500, that is, the test paper score is higher than half of the candidates, and the standard score is 500."

Each candidate's standard score in a single subject will be multiplied by the corresponding subject weight after conversion. The weights of Chinese, Mathematics and English are all 1.5, and the weights of other subjects are all 1.0. When the products are added together, the sum of the candidates' standard score will be obtained. Then, rank all the candidates' standard scores from high to low, and find the corresponding scores in the "comparison table" according to the percentage of ranking. This score is the comprehensive standard score of candidates.

In addition, the scores of all subjects in the basic examination are not converted into standard scores, which are counted as 10% of the total scores of all subjects. The comprehensive standard plus 10% of the basic test score is the final score of the college entrance examination.
