In Singapore, Sec 3 is the start of many students’ academic journey towards their O levels. For most, this is the first time they are introduced to the subjects that they will be taking for their GCE Ordinary Level examinations.

The importance of these subjects cannot be understated; they form the foundation upon which students will build their knowledge in upper secondary and tertiary education. And among all the subjects, O level Physics is particularly crucial. Here’s why:

The Importance of O level Physics

We’ll explore the importance of O level Physics from three perspectives: its utility, its difficulty, and its potential.


You might be wondering: “What use is Physics in my everyday life?” The thing is, we use Physics all the time without even realizing it. From using a simple magnifying glass to understanding how our electronic devices work, Physics is all around us.

But O level Physics isn’t just about understanding the world around us. It is also useful in other academic disciplines.


O level Physics is widely considered to be one of the most difficult subjects for students, and for good reason. It builds upon the concepts learned in lower secondary school and adds a new level of complexity.

This can be daunting for students, but it’s important to remember that difficulty is not bad. Overcoming challenges is how we learn and grow, and O level Physics is an excellent opportunity to do just that.


Last but not least, O level Physics is a great stepping stone for students who wish to pursue a career in Science, Technology, Engineering, or Mathematics (STEM). A sound understanding of Physics is essential for success in these fields, and O level Physics is the perfect foundation.

Now that we’ve seen the importance of O level Physics, it’s time for the more practical reasons why you should take Physics seriously and consider going to a Physics tuition center. 

1. O level Physics is crucial to understanding other disciplines

O level Physics forms the foundation for many other disciplines, such as Chemistry, Biology, and Earth Sciences. A strong understanding of Physics concepts will help you in:


O level Physics provides a strong foundation in Mathematics. Many concepts in Physics, such as vectors and trigonometry, are directly related to Mathematics. Understanding these concepts will give students an edge in their Math examinations.


O level Chemistry builds on the knowledge acquired in Physics. In particular, many concepts in Quantum Mechanics are essential for understanding modern Chemistry.


O level Biology also relies heavily on Physics. Concepts such as energy and cell membranes are key to understanding how living organisms work. Physics is especially useful when studying topics such as photosynthesis and respiration.

Earth Sciences:

O level Earth Sciences builds on the knowledge of Physics and Chemistry. For example, the study of plate tectonics requires an understanding of the Earth’s gravity and magnetic fields – both of which are concepts studied in Physics.

2. O level Physics is useful for careers in STEM

A strong understanding of Physics is essential for many careers in Science, Technology, Engineering, and Mathematics (STEM). Some examples of careers that require Physics include:


Doctors use Physics concepts such as waves and sound to diagnose patients using ultrasound machines. They also use knowledge of the human body’s electrical system to treat conditions such as heart arrhythmia.

Aerospace engineering:

Aerospace engineers use Physics to design and build aircraft and spacecraft. They need to understand aerodynamics, which is the study of how air interacts with objects in motion.

Environmental science:

Environmental scientists use Physics to study the Earth’s climate and weather patterns. They use knowledge of atmospheric physics to understand the greenhouse effect and global warming.

O level Physics is a subject with many real-world applications.

Secondary school students planning to pursue a career in STEM should consider attending O level Physics tuition to keep up and get ahead in their studies.

3. University admission looks at your O level Physics grades

For students intending to go to university, strong O level Physics grades are essential. Many universities use O level results as part of their admission criteria.

In addition, most degree programs in STEM require students to have a good understanding of Physics concepts. Some universities even offer scholarships specifically for students with excellent O level Physics grades.

Even if you’re not planning to pursue a career in STEM, many universities still recommend or require students to take O level Physics. This is because Physics is considered to be a good foundation for other degree programs.

Sure, it doesn’t seem fair that students who don’t want to study Physics have to take the subject. But that’s just the way it is.

You get an edge in admissions.

Did you know that some universities use O level Physics results as part of their admission criteria? This means that having strong grades in Physics can give you a leg up when applying to university.

Sure, your O level Physics grades aren’t the only thing that matters. But they can give you a valuable boost, especially if you’re applying to a competitive university.

4. Employers value O level Physics grades

In today’s competitive job market, employers are looking for any edge they can get. This means that they’re not just looking for employees with the right qualifications but also those with the right grades.

For many jobs in STEM, a strong understanding of Physics is essential. For example, employers in the aerospace industry will be looking for candidates with excellent O level Physics grades.

But it’s not just jobs in STEM that value O level Physics grades. Many employers, regardless of their industry, see good grades in Physics as a sign of intelligence and drive. Yup, it’s yet another example of how O level Physics can help you get ahead in life.

5. You can use O level Physics to impress people.

There’s no denying it: some people are impressed by good grades in O level Physics. When you tell someone that you got an A* in Physics, they might be impressed (or even intimidated).

And while impressing people might not be the most important reason to study O level Physics, it can’t hurt. After all, you never know when you might need to impress someone important (like a potential employer).

How can you improve your O level Physics grades?

If you’re not happy with your current O level Physics grades, don’t worry. You can do plenty of things to improve your performance in the subject. Here are a few tips:

1. Get a tutor:

If you’re struggling to understand the material, consider getting a tutor. A good tutor can help you to fill in any gaps in your knowledge and improve your understanding of the subject. Here’s How to choose the best tutor in Singapore

2. Relate physics concepts to every practice question.

Practicing without understanding the physics concepts will not help to improve grades. After all, just repeating the questions will not help one understand how to answer them. 

In Learning for Keeps, for one, they believe in promoting conceptual understanding and application of physics concepts in students, and not merely the acquisition of problem-solving skills.

3. Stay organized:

It’s important to stay organized when studying for O level Physics. This means keeping track of your progress, setting goals, and making a study schedule. Staying organized will help you to make the most of your time and improve your chances of getting good grades.


For all parents and students out there, we hope this article has helped to highlight the importance of O level Physics. If you’re still on the fence about whether or not to invest time on the subject, we hope that this article has convinced you to give it a try. Trust us, it’ll be worth it in the end.
