What High School Classes Should I Take to be an Engineer?

Great question—and a very smart one to ask early! If you’re planning to pursue engineering, the subjects you choose in high school will lay the foundation for your future studies. At any Singapore international high school, you’ll usually have access to globally recognized curricula like the IB (International Baccalaureate), IGCSE, or AP—all of which offer excellent preparation for engineering.

📘 Core Subjects You Should Definitely Take:

Mathematics (Higher Level if possible) This is the most important subject for any engineering discipline—whether it’s mechanical, civil, software, or aerospace. Focus on:

Algebra

Calculus

Trigonometry

Statistics

Physics Physics is crucial for almost all engineering branches, especially mechanical, electrical, and civil. It teaches you how things move, interact, and respond to forces.

Chemistry Important for chemical, environmental, materials, and biomedical engineering.

Computer Science / Programming Increasingly relevant in modern engineering fields, especially software, AI, and robotics. Most Singapore international high schools now offer coding or CS classes, either as electives or in the main curriculum.

💡 Bonus / Recommended Subjects:

Design & Technology – Great for hands-on learners, and relevant for product design, mechanical and industrial engineering.

Economics or Business – Helpful if you're thinking of entrepreneurship in engineering later on.

Environmental Systems & Societies (ESS) – Especially relevant if you’re considering sustainable or civil engineering.

🏫 Why Singapore International High Schools Are a Great Starting Point:

Many Singapore international high schools offer state-of-the-art labs, robotics clubs, coding bootcamps, and STEM-focused extracurriculars. These opportunities let you:

Build real projects

Join international competitions (like robotics or math olympiads)

Get hands-on experience early

Schools like UWCSEA, Stamford American International School, and Tanglin Trust School have excellent track records of placing students into top global engineering programs.

If you’re planning to pursue engineering, it’s important to build a strong foundation in math and science early on. In terms of the high school equivalent in Singapore, here are some key subjects to focus on:

Mathematics: Advanced math courses, including calculus and algebra, are essential. Strong math skills are the backbone of all engineering disciplines.

Physics: Physics helps you understand the principles behind mechanics, electricity, and materials — all core to engineering.

Chemistry: Useful especially for chemical, materials, or biomedical engineering.

Computer Science / ICT: Programming, coding, and computational thinking are increasingly important in modern engineering.

Electives / Applied Subjects: Some students also benefit from design and technology or robotics courses if available, as these give hands-on experience.

For students in Singapore, completing the high school equivalent in Singapore typically means O-Levels or an IB Diploma with strong emphasis on math and science subjects. Choosing these subjects will prepare you well for university-level engineering programs.

If you’re planning to become an engineer, selecting the right subjects in high school is a crucial step. A strong combination of math, science, and technical skills will prepare you for university engineering programs and future career opportunities.

In a Singapore international high school, students benefit from globally recognized curricula and a structured academic pathway that supports STEM (Science, Technology, Engineering, and Mathematics) learning. Schools like One World International School (OWIS) provide an environment where students can explore these subjects in depth while also developing practical skills.

Recommended High School Subjects

1. Mathematics (Core Subject)

Focus on advanced math courses such as algebra, trigonometry, and calculus. These are essential for all engineering disciplines.

2. Physics (Highly Recommended)

Physics is fundamental to understanding how systems work—covering concepts like forces, energy, electricity, and motion.

3. Chemistry

Useful for specialized fields like chemical, environmental, or biomedical engineering.

4. Computer Science / Programming

Coding and computational thinking are increasingly important in engineering, especially in areas like software, robotics, and AI.
