As the other poster said: raw scores are simply how many points were scored by each candidate.
Most GL systems have cohort marking, they stack the candidates into raw score order (usually they also sort them into 12 birth months so the August cohort are standardised together, the April conort are standardised together, which removes the age bias). So each candidate will have a ranking, from highest to lowest raw score.
So they then fix their “pass raw score” where the desired percentage of candidtates pass: the actual number varies with every cohort, because it’s the number needed to be eg in the top 30% . They then mathematically convert it to create a standardised score according to how close in either direction each child’s score is to the pass mark.
so it’s not linear: and the raw score needed is “enough to beat 70% of the cohort in that exam”.
which means it doesn’t matter what your DCs raw score is as such. As Etienne says, what matters is the academic evidence you present that your DC is academically high achieving and has the ability and aptitude to do well at a grammar school.
