JC Subject Selection Guide 2026: How to Choose Your H2 and H1 Subjects

Subject selection at JC is not just about choosing subjects you like — it's a strategic decision that affects your university options, career trajectory, and overall A-Level success. Many students choose subjects based on peer pressure or perceived prestige, only to struggle later. This guide helps you make an informed decision.

Understanding H2 vs H1 Subjects

H2 subjects are taken at a higher level of depth and difficulty (4 hours per week). H1 subjects are taken at a lower level (2 hours per week). Most universities require specific H2 subjects for certain courses. For example, NUS Engineering typically requires H2 Mathematics and H2 Physics. H1 subjects are more flexible and often used to explore interests outside your main specialisation.
