Examination time: 3 courses and 2 opportunities, each year 1 or June (only for senior three students), and the results are valid in that year.
"The new college entrance examination policy in Zhejiang Province stipulates that the subjects to be selected should be selected from seven subjects: politics, history, geography, physics, chemistry, biology and technology. There are two opportunities for three exams, and the time is 1 or every June (only for senior three students). The result is valid in that year. The grades are graded. From June 65438+ 10, 2022, the scoring difference of the selected subjects was changed to 1, and the scoring rules are as follows: the conversion method is to calculate the candidates' scores according to everyone's scale scores and the upper and lower limits of the scores, combined with the actual scores of the candidates' scales, and convert them in equal proportion (the scoring results are rounded to the whole number). ?
The specific operation steps are as follows:
A divide the test scores into 20 designated areas according to the following proportion of people.
B, according to the first step, get four values of each interval. They are the highest score (upper limit), the lowest score (lower limit), the highest score (upper limit) and the lowest score (lower limit) of each interval.
C, according to the four values in the second step, according to the actual scores of the students' test papers, and through the proportional conversion formula, the final score t of the candidates is finally obtained.
When calculating, the equation is solved by diagonal multiplication and equality, and the final score t of the students is obtained.
D. round off the final score t of the candidate. (only look at the first place after the decimal point, greater than or equal to 5, and the value before the decimal point is+1; Less than or equal to 4, the value before the decimal point remains unchanged)
