Why Students Should Take O Level Computing in Singapore

Posted on August 4, 2025

If you’re a secondary school student in Singapore and still deciding on your subjects, let me just say — O Level Computing is one of the most underrated ones out there.

1. Tech is everywhere — and it’s not going away

We’re living in a time where everything runs on tech. Ordering food? App. Booking a cab? App. Even your kopi shop uncle is using PayNow now. Learning Computing means you’re not just a user — you understand how things work behind the scenes. You’ll learn programming, problem-solving, algorithms, and data handling. It’s like solving puzzles, except the answers can make your computer or phone actually do something cool.

2. It’s not “just for IT people”

Many think Computing is only for future software engineers or “hackers” (thanks Hollywood). But really, it teaches logical thinking — useful in almost any career, from business to design to engineering. If you’re eyeing poly courses like Infocomm, Cybersecurity, AI, or Game Development, Computing gives you a head start. And even if you end up in a totally different field, knowing tech still makes you stand out.

3. Hands-on learning (less memorising!)

Let’s be honest — some subjects are just mugging until your brain dies. Computing is different. Sure, there’s theory, but a lot of it is practical coding and problem-solving. Instead of memorising essays, you’ll be typing code, testing programs, and seeing instant results. And when your code works, the feeling is shiok.

4. Demand for tech skills

Singapore is going all-in on becoming a Smart Nation. That means tech skills is valuable. If you start early with O Level Computing, you’ll have a head start in coding and design thinking, which leads to opportunites and even side hustles like freelance app building or website design.

5. It’s actually fun

If you enjoy challenges, figuring things out, and that “Eureka!” moment when something finally works, you’ll love Computing. Plus, you can use your skills for personal projects — building a website, making a simple game, automating boring tasks, or even coding a chatbot for fun.

Final thoughts

If you’re still considering whether to take O Level Computing, think about where the world is heading. Tech isn’t slowing down, and the earlier you learn, the more you’ll benefit later. Don’t just take it because it’s “in trend” — take it because it’s an investment in yourself. Who knows? That first line of code you write in Sec 3 might just lead to your dream job one day.
