Combined Science vs Pure Science: Which Do I Pick?

Combined Science vs Pure Science: Which Do I Pick?

Choosing between Combined Science and Pure Science is one of the most important decisions secondary school students face during their Sec 3 subject streaming.

This guide breaks down the key differences between these options, helping you make an informed choice that aligns with your academic goals and future aspirations.

Combined Science Stream

Combined Science

Combined Science allows students to select two out of three science disciplines—Biology, Chemistry, and Physics—as their focus areas. Students may choose the third subject as a Pure Science option or drop it entirely from their curriculum.

The Combined Science syllabus offers a multidisciplinary approach with a broader scope but less complexity than Pure Science subjects. It contains roughly 75% of the content compared to Pure Science, making it less demanding while maintaining the same generalist approach students have been familiar with over the past two years.

Pure Science Stream

Pure Science

On the other hand, Pure Science subjects are generally more challenging than Combined Science, offering students who excel in science the opportunity to pursue Triple Science, where all three disciplines are studied as separately graded subjects. Alternatively, students can take one Pure Science subject while combining the other two as Combined Science.

These subjects provide in-depth knowledge that focuses on information directly relevant to actual scientific fields. Pure Science emphasises hands-on laboratory work and a more immersive learning approach, teaching practical knowledge applicable in real-life scientific settings.

Students should be prepared for a content-heavy curriculum, which includes a substantial amount of scientific principles and formulas to master.

Things to Consider When Selecting Science Syllabus

How to Decide Between Pure Science or Combined Science

1. Intended Course in Tertiary Education

Some Polytechnic courses, like Biochemistry, require Pure Science for admission. Students planning to pursue science-related careers should select Pure Science subjects that align with their intended tertiary courses.

2. Interest and Expertise

Students who lack an interest in science or already struggle with the subject may find it challenging to manage multiple demanding Pure Science subjects. If a student excels in other subjects and doesn't plan to study science-related courses after secondary school, focusing on achieving strong results in Combined Science may be the optimal choice.

3. Grading Split

Combined Science results are consolidated into one overall science grade, which can be problematic for students who excel in one specific subject but struggle with another. In such cases, splitting subjects through Pure Science options allows students to focus on their strongest areas and achieve better individual subject grades.
