A-LEVEL COURSE REQUIREMENTS

The GCE A-Level curriculum requires students to offer the following subjects:
- 3 H2 and 1 H1 content-based subjects (at least one of which must be from a contrasting discipline),
- H1 Mother Tongue Language (MTL),
- H1 General Paper (GP)
- Project Work (PW).
Students who have obtained 10 points or better for their L1R5 raw aggregate, AND 8 points or better in their 4 relevant O-Level subjects are eligible to take 4 H2 content-based subjects, of which at least one must be from a contrasting discipline.
Students who offered O-Level MTL are required to offer H1 MTL at JC1. Students who achieved a grade of D7 or better in O-Level Higher MTL are exempted from taking H1 MTL. Students who offered Mother Tongue B Syllabus (MTB) at O-Level will continue with MTB at GCE A-Level.

Students who wish to take H2 ELL are required to sit for and pass a selection test before a place can be confirmed.
For subject combinations with low demand, the College reserves the right to decide whether such subject combinations would be offered.

MERIT-BASED ALLOCATION

Taking into consideration the number of applicants and the number of places available for each subject, the College adopts a merit-based allocation process in the selection of students for the subject combination they have opted for.
In the event that a subject is over-subscribed, students will be selected based on academic merit, including
- L1R5 raw aggregate (excluding bonus points) or equivalent;
- performance in the relevant subject(s).

Table D provides additional information regarding subject allocation:

H3 SUBJECTS

H3 subjects are offered to students who are academically strong and desire to pursue a subject or area in which they have passion and aptitude. These students must be prepared to manage a workload beyond the normal subject combination. To read a H3 subject, students are required to take the corresponding subject at H2 Level. Please note that H3 subjects are ONLY offered to students in JC2.
- Students may be offered a H3 subject in the following areas if they have done well in their overall examinations at the end of JC 1, including a high ‘A’ grade in the corresponding subject at the H2 level.
  - University-taught H3 programmes (NUS, NTU and SMU)
  - NUS-MOE Humanities And Social Sciences Research (HSSR) H3
  - MOE-Cambridge H3
