If an article is assigned 120 uniform points, the range of grades assigned to grade B is 84 to 95 (70 to 79% of 120); for grade C, 72 to 83 (60 to 69% of 120). Students pursuing science will take one or more separate sciences (biology, chemistry, and physics) or combined sciences. GCSE grade limits tell us the number of gross grades a student must achieve to receive a given grade. For those studying physics, a score of 60% would equate to a grade C.
This is because the range for a grade C is 72 to 83 (60 to 69% of 120). Students will study biology, chemistry, and physics, but those taking combined sciences will not cover as much content as those students in separate sciences. This would be common with most year 7 students, since a grade 3 in year 7 is not fully equivalent to a GCSE grade.
