The total score of Hainan college entrance examination is 900, which belongs to the standard score. Hainan Province has a set of achievement conversion formulas, which are divided into standard scores and original scores.

Hainan college entrance examination total score 900 standard score conversion

Single subject standard score conversion

The standard scores of single subjects include: unifying the standard scores of six subjects, such as Chinese, mathematics, English and the selective examination of ordinary high school academic level, politics, history, geography, physics, chemistry and biology.

According to the norm scale of standard normal distribution and the conversion formula Ti= 180+30×Zi, a cross-reference table of standard score and percentile score (single subject)-score interval is established.

(1) Sort the original scores of all candidates in this subject from big to small.

(2) Calculate the percentage of candidates with scores less than or equal to Xi in the total number of candidates in this subject, so as to find the percentage grade Ri of each score Xi.

(3) Check the comparison table between the standard score and the percentage grade (single subject)-score interval to obtain the single subject standard score Ti corresponding to each percentage grade Ri.

Comprehensive analysis and transformation

The comprehensive score is the result of unifying the standard score of the college entrance examination subjects and the standard score of the selected subjects according to their respective weights.

According to the norm scale of standard normal distribution and the conversion formula Ti=500+ 100×Zi, the comparison table of standard score and percentile grade (comprehensive score)-score interval is established.

(a) according to the language, mathematics, English each subject weight is 1.5, other subjects weight is 1, calculate the total score of each candidate, the calculation formula is:

t = 1.5×Tyw+ 1.5×Tsx+ 1.5×Tyy+tx 1+Tx2+Tx3

Among them, Tyw, Tsx, Tyy, Tx 1, Tx2 and Tx3 are the standard scores of Chinese, mathematics, English, elective subject 1, elective subject 2 and elective subject 3 respectively.

(2) Rank all the candidates' synthetic total scores T from big to small.

(3) Calculate the percentage of candidates less than or equal to each comprehensive total score ti in the total number of candidates, so as to find the percentage grade Ri of each comprehensive total score.

(4) Check the comparison table of standard score and percentage grade (comprehensive score)-score interval to get the comprehensive standard score Ti corresponding to the percentage grade Ri of each comprehensive total score.

Hainan boys scored 900 points in the college entrance examination and went to Tsinghua on July 15. Wu Jingtai, a candidate from Hainan Province, received the admission notice from Tsinghua University.

I scored 900 points in the college entrance examination, and this year I was admitted to Weiyang College in Tsinghua University through the Strong Foundation Program, majoring in basic mathematics science+microelectronics science and engineering.

I chose Weiyang College and Microelectronics as my engineering degree. Wu Jingtai said that when I attended the summer school held in Tsinghua University in Hainan last year, I heard Mr. Ye Zuochang's report on chips from the Institute of Integrated Circuits, and learned that chips are a technical problem stuck in China. So I became interested in the study and research related to integrated circuits and decided to devote myself to the key field of chips, hoping to combine my interests with the needs of national development.

Wu Jingtai said, "At present, the country urgently needs talents in the direction of chips. The main reason for applying for the strong foundation program is that I hope to make some contributions to the country in the future. "
