There is a relevant passage embedded, but not expanded upon, in the original article: >Whether a student passes or fails is dependent on a combination of two assessments; >a report from their junior high school marked out of 300 points >and a written test covering Japanese, math, English, science and social studies and scored out of 700. The report is worth up to 300 points which is about 10x the typical differentials mentioned in article. Going by the condensed explanation in article, is created by the junior high teacher(s?) of the pupil. I suspect a scoring inflation, quite possibly gender-selective - specifically to prop up pupils the teachers perceive as worthy moving onward.
