How to identify your school course
Secondary
- Look at your subject combination or school learning portal.
- Find the level printed beside Science or Chemistry.
- Do not assume every subject uses your posting-group level.
Still unsure? Ask your school which syllabus code you are taking.
A-Level
- Check your school timetable or examination registration.
- Match the Chemistry subject code: 8873 for H1 or 9476 for H2.
- If you take H3 9813, keep H2 9476 as your primary course.
Ask your school if the subject code is not shown clearly.
