作为一个老司机，我来告诉你
学校分 没有什么用处， 关键是排名 （你可以查 以前我的帖子）
想当初，我女儿英文９５ 分 排名第十五。
考试的每一道题目没有分数， 只是根据对的题目数进行数理统计，很复杂。
它和你在学校的排名有联系， 和 整个学校的每一个学生的考试成绩有关系。
要得到一个好的分数， 要某学生的学校排名高，要考得好，要 同学也考得好。
所以如果考得题目对的题目数是一样，但是分数绝对是不一样。
再说 我也不认为 OC 有什么好
这个是 SELECTIVE 但是 OC一样。
In general, entry into a government selective school is determined by a profile score, which is derived by combining school marks in English and mathematics with the marks received in the Selective High Schools Test in reading, writing, mathematics and general ability.
The profile score is computed by adding together component scores for English, mathematics and general ability, each of which are marks out of 100, to form the profile score out of 300.[11]
As of 2019 the component scores are computed as follows:[11]
In general ability the test marks are scaled on a statewide basis to a mean of 60 and a standard deviation of 12 to form the component general ability score out of 100.
In mathematics, the component score is the scaled average of the scaled test mark and the moderated school mark. The raw test marks are scaled on a statewide basis to a mean of 60 and a standard deviation of 12 to form the scaled mathematics test marks out of 100. School marks are scaled on a school-by-school basis. The distribution of mathematics school marks for each school is scaled to the same mean and standard deviation, as the mean and standard deviation of the scaled test marks for students at that school. This accounts for different marking standards in different schools. A student's raw school mark, scaled according to this adjusted distribution, is the moderated school mark. The scaled test mark and the moderated school mark for each student is averaged, and the average is then re-scaled on a statewide basis to the mean of 60 and standard deviation of 12 to form the final component score out of 100.
In English, the component score is the scaled weighted average of scaled reading and writing scores. The process follows the process used for mathematics, except that the school mark is used twice - once moderated according to reading test marks for the school and averaged with the scaled reading test score, and a second time scaled according to writing test marks for the school and averaged with the scaled writing test score. The average reading score is given a weighting of two thirds and the resultant scores for writing are given a weighting of one third. These two scores are then added and re-scaled on a statewide basis to a mean of 60 and a standard deviation of 12 to form the final component score in English out of 100.
Scaling and moderating school and tests marks ensure that:[11]
school and test marks have the same value;
school marks from each school are placed on the same scale as the test marks achieved by students from those same schools thereby making it possible to fairly compare school marks from one school with school marks from each other school; and
each component (English, mathematics and general ability) has the same value.
The process also includes 'wild-score' processing which identifies students who, based on their school performance, may have done much worse than expected in the test. Where such students have been identified the moderating process takes this into account and adjusts scores accordingly. This ensures that students will not be disadvantaged by other students who attend the same school and may have done much worse than expected because of serious illness, misadventure or other cause.
