At the end of Secondary 2, your teen will need to choose their subject combination for the upper secondary years. These choices can influence the post-secondary courses they qualify for after Secondary 4.

A new development to note: from 2027 onwards, Secondary 4 students will sit for the new Singapore-Cambridge Secondary Education Certificate (SEC) exams, with different papers based on subject levels. Results will be released in early 2028 and used for post-secondary applications.

With these changes ahead, should your teen approach their subject selection differently? Read on to find out!

What subjects are offered in Secondary 3?

Subject offerings vary by school, and it’s best that you check with your teen’s school about their selections.

In general, secondary school subjects fall into two categories: compulsory subjects and choice subjects.

Compulsory subjects are taken by all students, and these are:

• English Language
• Mother Tongue
• Mathematics

Choice subjects depend on the student’s interests, academic strengths, and school offerings. These may include:

Pure Sciences

• Biology
• Chemistry
• Physics

Combined Sciences

• Science (Physics, Chemistry)
• Science (Chemistry, Biology)

Pure Humanities

• Geography
• History
• Literature in English

Combined Humanities

• Social Studies + Geography
• Social Studies + History
• Social Studies + Literature in English

Elective Subjects

• Additional Mathematics
• Principles of Accounts
• Computing
• Art
• Design & Technology
• Nutrition & Food Science

Do check with your child’s school if you have any questions about subject offerings. To see an example of what a mainstream secondary school might offer, you can visit Bedok South Secondary School’s website, which has dedicated subject pages outlining the curriculum, teaching approach, and key learning objectives for each subject.

How are Secondary 3 subject combinations typically allocated?

If you attend a school briefing on subject combinations, you will likely hear that subject allocations are based on three factors:

• Merit: a student’s academic performance
• Choice: what a student has indicated is their preference
• Availability: the subjects that are available in a school, and the number of vacancies versus demand

In the past, some secondary schools would recommend an eight-subject combination to their better-performing students:

2 Languages + 2 Mathematics + 2 Science + 2 Humanities

This combination was once seen as a way to keep as many post-secondary options open as possible. 

However, the admission criteria for A-Level pathways will soon be updated, and schools may no longer encourage students to take on a heavier subject load purely for strategic advantage.

What are the new entry requirements for JCs and the Millennia Institute?

From 2028, students applying to junior colleges (JCs) will be assessed based on five subjects instead of six, under a revised scoring system known as L1R4. 

This replaces the current L1R5 system, which requires a score of 20 points or better across six subjects. The L1R5 system stands for:

• L1: First Language (usually English or Higher Mother Tongue)
• R5: Five relevant subjects, including a mix of humanities, science, and mathematics.

Under L1R4, students will be assessed on five subjects — a First Language, along with four other subjects:

• 1 best-scoring subject from Humanities
• 1 from Mathematics or Science
• 1 from any of the three groups above
• 1 from any subject area

Students will qualify for JCs if they score 16 points or better. 

Keep in mind that any bonus points (such as those from CCA achievements or taking Higher Mother Tongue) can reduce the total score, but this will be capped at three bonus points from 2028.

It’s worth noting that Millennia Institute (MI), which offers a three-year A-Level programme, has always used L1R4 as its admission benchmark.

This is the current MI criteria:

• English or Higher Mother Tongue Language
• 2 best-scoring subjects from Humanities, Mathematics, or Science
• 2 from any subject area

The new MI criteria (from 2028) will be similar to the JC L1R4 requirements outlined above. The difference is that MI’s entry score will remain at 20 points.

For those considering the polytechnic or Institute of Technical Education (ITE) pathways, admissions have always been based on students’ performance in five subjects, though the subject groupings vary depending on the course.

In general, polytechnic courses require English, two relevant subjects, and two other best-performing subjects — with some courses specifying subject prerequisites like Mathematics or Science. Similarly, ITE admissions are based on English and four other best subjects, with certain courses requiring specific subjects.

How will the new JC requirements affect Secondary 3 subject combinations being offered from 2026?

With the shift to L1R4 for JC admissions from 2028, the pressure to take an eight-subject load has eased.

Some schools may shift to offering fewer subjects, so that students can have more time for other pursuits. Schools may also do away with certain combinations, such as “triple science,” where students take Chemistry, Physics, and Biology. This information is best obtained directly from your teen’s school.

Hoping that your teen can take more subjects? 

This is a tip we picked up recently from a local school talk: for each additional subject that a student takes on, this requires an additional three hours of curriculum time per week. You should also factor in time for homework, revision, and tutoring or other forms of academic support if needed.

Another common concern is whether students should take pure science subjects (rather than combined science, where topics from two pure science subjects are combined to form one subject) and Additional Mathematics.

Here’s some advice from AskMrChan, a Chemistry-focused enrichment centre that supports secondary school students: If your teen enjoys science, is coping well, and is considering the junior college route, taking pure sciences like Chemistry can help lay a stronger foundation for A-Level subjects.

That said, combined science still equips students with essential concepts and skills, making it a suitable option for those who prefer a broader exposure or want to keep their future pathways open. 

Among the pure sciences, Chemistry is often considered essential, especially for students eyeing fields like medicine, life sciences, or environmental studies. If your child needs Chemistry support and hopes to learn Chemistry from the best, AskMrChan offers O-Level, IP, IB, and A-Level Chemistry tuition, led by experienced MOE-trained tutors using proven resources and teaching methods.

You should also be aware that in junior college, H2 (Higher 2) subjects are more in-depth and demanding than H1 (Higher 1) subjects, and are typically required for university admission.

For A-Level subjects like H2 Mathematics, most junior colleges require students to have taken Additional Mathematics (A Maths) at the secondary level. Yishun Innova Junior College has a guide on this, which you can read.

To avoid disappointment at a later stage, your teen should plan ahead and check with their preferred junior colleges about the subject requirements. For instance, St Andrew’s Junior College advises its students to choose a combination that has only one science subject at H2 level, if they did not take pure science subjects in secondary school.

While your teen is considering subject combinations, they can use these guiding questions:

• How many subjects do I want to take, and why? 
• What kind of subjects am I more confident or interested in?
• Will these subjects be relevant for my post-secondary goals?
• Do these subjects play to my strengths and interests?

Encourage your teen to reflect honestly, and seek advice from teachers or career guidance officers if unsure.
