If you’re entering JC or choosing your subject combination, you’ve probably heard this question: H1 vs H2 Math? Which subject should I choose? And if you’re unsure, you’re not alone. Many students — even top scorers struggle to make this decision.
Getting this choice right can impact your future university options and academic confidence. Let’s break down the key differences, risks, and decision-making tips to help you make an informed choice.
What’s the Difference Between H1 and H2 Math?
H2 Math is a full A-Level subject and covers advanced topics such as calculus, vectors, functions, complex numbers, and statistics. It builds on the Additional Math syllabus at O-Level.
H1 Math, on the other hand, is a simplified version, focusing more on statistics and less on algebra-heavy content. It’s more accessible, especially for students without A-Math background. The pure math section in H1 is mainly A-Math.
| Aspect | H1 Math | H2 Math |
|---|---|---|
| Content Depth | Moderate | High (A-Math required) |
| Duration | 1 paper (3 hours) | 2 papers (3 hours each) |
| University Eligibility | Limited for STEM courses | Required for many STEM, Biz, Computing degrees |
| Weightage in RP | H1 subject | H2 subject |
When Is H2 Math Required?
H2 Math is compulsory or highly recommended for many competitive and math-related university courses:
- Engineering
- Computer Science / Data Science
- Architecture
- Business Analytics
- Economics at NUS/NTU/SMU
For example, NUS Computing and Engineering require a good pass in H2 Math. Even certain Psychology and Science majors look for strong math backgrounds.
When Might H1 Math Be the Better Choice?
If you:
- Struggled with A-Math in secondary school
- Are planning to pursue Arts, Humanities, or Social Sciences related degrees
- Don’t need Math for your intended university course
…then H1 Math may make more sense. It frees up time to focus on your strengths and prevents unnecessary stress.
What If You Regret Your Choice Later?
Many students realise they need H2 Math only after it’s too late. Unfortunately, switching from H1 to H2 is nearly impossible once school starts — and retaking H2 Math as a private candidate is tough without structured support. However, you can always drop H2 Math to H1 Math later on.
That’s why it’s important to evaluate early. If you’re unsure, speak to your teachers, review your A-Math results honestly, and consider your career aspirations.
What Mr Lim Recommends
Mr Lim has worked with hundreds of students in H2 Math. His advice?
- If you’re aiming for a competitive STEM or Business degree, go with H2 — but get support early.
- If you’re borderline, try H2 first and assess within the first term — switching down is easier than switching up.
Final Thoughts: Choose with the Future in Mind
It’s not just about “easier” or “harder.” It’s about what serves your goals. H1 vs H2 Math both have their places — but H2 Math keeps more doors open.
