For standard subjects, we apply the following formula:
T = 50+10 [(x-m)/s]
where x is the candidate’s mark for the subject Q
m is the average mark (mean) scored by all the candidates
The grades for each Standard subject are awarded A* (highest grade for standard subjects) or A, B, C, D, or E (lowest grade for standard subjects). For Foundation subjects, the grades awarded are Grade 1(highest grade for foundation subjects), 2, 3 or 4 (lowest grade for Foundation Subjects). Higher Mother Tongue subjects are awarded Distinction (Highest grade for Higher Mother Tongue Subjects), Merit, Pass (lowest grade for Higher Mother Tongue Subjects)."Ungraded" is awarded for those subject(s) that a student did not achieve the requirement of a minimum grade for the subject or the students missed all the papers for the subject during the PSLE.
