The O level scoring system is not the easiest one to understand. You’ll hear students throwing around terms things like L1R5, contrasting subjects, and different requirements for JC and poly. How does it all work?
For parents or O level students still in the fog, here’s our quick explainer of the O level L1R5 scoring system for JC – and we’ve included the cut-off points for our local junior colleges at the end of the article as well.
What is L1R5?
- L1: 1 Language Subject
- R5: 5 Relevant Subjects
L1R5 sounds like code for the new model of smartphone – or a friend of Star Wars’ R2D2! But let’s take it part by part, and you’ll see it is not too hard to understand.
First, L stands for Language, and 1 means 1 subject. This takes into account the grade for the student’s first language – in most cases, English. Students who have a good score for Higher Chinese may also use it as their L1.
R stands for relevant, and 5 means 5 subjects. Thus, R5 refers to the best scoring 5 relevant subjects, apart from what you already used for L1.
What counts in the R5?
- At least 1 math or science subject
- At least 1 humanities subject
Higher Music, Higher Art, Malay Special Programme, Chinese Special Programme, or Bahasa Indonesia can also be qualified as a humanities subject.
Exceptions: You can’t have both your Higher MTL and MTL subjects counted in. So, if you scored A for both Higher MTL and MTL, you can only use one of the As.
Students taking Mother Tongue ‘B’ languages also can’t use their grade if it is ‘merit’ or ‘pass’.
