The L1R5 score is used for the admission process to secondary schools in Singapore and is calculated based on a student’s performance in their “O” level exams.

The L1R5 score takes into account grades obtained in the first language (L1) subject (e.g., English), five relevant subjects (R5), and the sum of their raw scores.

While science subjects are essential components of the secondary school curriculum in Singapore, they are not mandatory to be included in the L1R5 scoring system. However, it’s important to note that individual schools may have their own specific subject requirements for admission, and some schools might prioritize students with strong performances in science subjects.

Therefore, it’s advisable for students to check the specific admission criteria of the schools they wish to apply to.
