3 Combined Science is offered in such a way as to provide space for students to take up other non- science elective subjects. It still provides a concrete foundation in Science for further studies or careers. Students wishing to take two elective subjects in Science are recommended to take one of the Combined Science electives together with one specialised science subject.

13 Students’ Questions Please introduce the syllabus. What proportion of each subject is covered? Is Combined Science (Vs pure sciences) recognized by universities? Will less be covered in Combined Science in comparison with a pure science subject? Is studying Physics, Chemistry, Biology separately better than doing Combined Science?
