It refers to the grading system adopted by RGS and RI in recording student performance scores for academic subjects in the Raffles Programme. The highest possible Grade Point (GP) for a subject is 4.0, which translates to 80 marks and above, 3.6 for 70-79, 3.2 for 65-69 and so on. The GPA is the overall average GP of six subjects - the five Core Subjects (English Language, Higher Mother Tongue/Mother Tongue, Mathematics, one Science and one Humanities subject), and the best remaining GP from the remaining subjects that a student takes.
