O Level Grading System

The Singapore-Cambridge General Certificate of Education Ordinary Level (or Singapore-Cambridge GCE O-Level) is a GCE Ordinary Level examination held annually in Singapore and is jointly conducted by the Ministry of Education (MOE), Singapore Examinations and Assessment Board (SEAB) and the University of Cambridge Local Examinations Syndicate (UCLES).

The 2024 GCE O-Levels results will be released tentatively between Friday, 10 January and Tuesday, 14 January 2025.

The L1R5 (JC Grading System)

The O level Grading System is for JC is calculated with the L1R5, which can be explained as follows:

L1 refers to the Language Subject and is usually English or a Higher Mother Tongue Subject.
*Do note that an ordinary level language cannot be considered as L1.

R5 refers to 5 other relevant subjects. This is based on whichever subject combination is taken, most students will take a combination of:

R1 Humanities Subject (Geography/ History/ Literature)

R2 Mathematics or Science

R3 Another one from the Humanities, Mathematics or Science.

R4,R5 Any 2 best scoring subject.

How to calculate the L1R5?

Simply put, the L1R5 is a calculation of all of the above based on the number behind the letter grades. An example would be as follows:

English – B3

Mother Tongue – B3

Geography – A2

Mathematics – B4

Combined Science (Physics and Bio) – A2

Literature – C5

Total L1R5 = 3 + 3 + 2 + 4 + 2 + 5 = 19

To be eligible for JC, the score must not exceed 20.

The L1R4 (Millennia Institute Grading System)

Similarly, as above the Polytechnic grading system follows the same calculations but only with 4 relevant subjects.

L1: Language Subject

R4: 4 relevant, excluding Chinese.

To be eligible for polytechnics, the score must not exceed 20.

The ELR2B2 System (Polytechnic Grading System)

The ELR2B2 System is the sum of English Language (EL), two relevant subjects (R2), and two best subjects (B2), minus CCA bonus points

EL: English Language

R2: 2 Relevant Subjects

B2: 2 other Best Scoring subjects

The slight difference in calculation is in the “Best Scoring subjects”.
This can include Food and Nutrition/ Arts/ DNT or any other relevant subjects.

To be eligible for polytechnics, the score must not exceed 26.

I was struggling with math and decided to join muscle math after attending a crash course. Ms Fou’s teaching method as well as her patience made me understood concepts that seemed difficult. Slowly with her guidance , I was able to learn new concepts easily and scored better in my school exams. She would also reply to my questions as soon as she saw it and I am grateful to have a math tutor like her :)

Musclemath has been a chief asset for me throughout JC. The worksheets, online resources and compiled booklets were instrumental in exposing me to diverse question types and methods. Every lesson is effectively planned and executed, with the tutors laying out the agenda beforehand, focusing on the key question types and allowing different students to move at their chosen pace. The materials are compiled in a very concise and digestible manner that makes them handy for both learning and revision. Mr Tan and Ms Fou are excellent teachers. They write out their workings step-by-step neatly, explain the thought process and include diagrams and proofs, thereby consistently promoting conceptual understanding rather than rote learning. They are also very sensitive to the students’ learning pace. They make it a point to check up on us during breaks or after class if we looked confused during the lesson. When answering questions, they really try to pinpoint the source of confusion and find new ways to explain the concept. They also respond to queries online very quickly, writing out and taking pictures of their method and recording their explanations. The admin staff are very supportive as well, in that they cater to students’ busy schedules by making it easy for us to opt for online lessons over face-to-face ones. They are also prompt in sending answer keys, rearranging classes and answering questions. The Musclemath team has worked closely with me to make sure I get the most out of their lessons, and have been instrumental in my learning.

Ms Fou is a patient teacher that takes times out of her own free time to answer any questions that students may have. She also tries to use examples and analogies to try and help students understand concepts

My experience at MuscleMath was very fulfilling and rewarding. Mr Tan and Ms Fou are both very approachable when I encounter difficulties. The lessons are well structured and engaging :)

Irene Lee

Enrolled my daughter in Muscle Math after J1 MYE. Glad that Mr Tan was friendly and could explain her weakest topic- Functions in the most comprehensive way for her. Ms Fou's lessons were great as well. Highly recommended!

Cindy Chua

A big shoutout to Mr Tan and Ms Fou for their dedication in teaching my daughter, THANK YOU! She managed to obtain an A for her H2 Math. Thank you for being available and approachable whenever she needed to clarify things that she didn't understand in her school. Thank you for helping her improve her confidence before the exams. Esp Ms Fou, thank you for showing my daughter that girls can also excel in Math. She really enjoyed your style of teaching. Also, many thanks to Ms Wong for handling the admin issues impeccably. She makes it really simple for the parents to be updated with the term, holiday or extra schedules.

Strongly recommend Mr Joshua from Muscle Math Tuition who helped my girl obtained an A in her A level H2 Math. Mr Joshua is a very patient and committed teacher. He never fails to answer all her questions and even stayed beyond class time to go thru difficult concepts with her. I strongly recommend Mr Joshua.

Yue Guo

Mr Joshua and Mr Jason are great tutors, recommended for H2 math and A math students who are in need.

Dinna Soon

I enrolled my son in Muscle Math Tuition since his was in JC1. Mr. Joshua is a very friendly and approachable tutor who always keeps his lessons interesting and engaging. He is happy to set aside time outside the lesson to clear any queries my son has. My son obtained an A in his A level H2 maths. Would highly recommend Mr Joshua to anyone who needs extra help in Maths.

Geraint Chow

I feel there’s a strong need to promote tutors like Joshua and Ms Fou as they are really dedicated and proficient in teaching JC mathematics. Joshua would stay back with me every week to clarify my questions and that made me really motivated to do well for A Levels. I eventually scored an A in A Level Mathematics! Thanks Joshua and Ms Fou, you guys made my dreams come thru! =)
