What is Secondary 2 SEC Math Syllabus in Singapore

In Singapore, the Ministry of Education (MOE) oversees the secondary mathematics curriculum, which as of 2024 operates under the Full Subject-Based Banding (FSBB) system.

This replaces the former streaming into Express, Normal (Academic), and Normal (Technical) with more flexible G1, G2, and G3 levels, allowing students to take subjects at different rigor based on their strengths. G3 represents the highest level, equivalent to the previous Express stream, and prepares students for advanced topics leading toward the GCE O-Level examinations.

The Secondary 2 syllabus builds on foundational concepts from Secondary 1, emphasizing problem-solving, real-world applications (such as map scales for travel or probability in decision-making), and logical reasoning. It is divided into three main strands: Number and Algebra, Geometry and Measurement, and Statistics and Probability.

Below is a detailed explanation of the G3-level syllabus for Secondary 2, as it aligns with the standard “SEC” (Secondary) Math often referred to in educational contexts; G2 and G1 are simplified versions for varying student needs.

Number and Algebra

This strand focuses on deepening algebraic manipulation skills and understanding relationships between quantities, which are crucial for modeling real-life scenarios like rates of change or financial proportions.

• Ratio and Proportion: Map scales (including distance and area calculations); direct and inverse proportion.
• Algebraic Expressions and Formulae: Expansion of products of algebraic expressions; changing the subject of a formula; evaluating unknown quantities in formulas; special expansions like (a + b)² = a² + 2ab + b², (a – b)² = a² – 2ab + b², and a² – b² = (a + b)(a – b); factorisation of linear expressions (e.g., ax + bx + kay + kby) and quadratic expressions (ax² + bx + c); multiplication and division of simple algebraic fractions (e.g., (3a/4b²) × (5ab³/3a⁴) ÷ (9a²/10)); addition and subtraction of algebraic fractions with linear or quadratic denominators (e.g., 1/(x-2) + 2/(x-3) or 1/(x²-9) + 2/(x-3)).
• Functions and Graphs: Quadratic functions (y = ax² + bx + c); properties of quadratic graphs (positive/negative coefficient of x², maximum/minimum points, symmetry).
• Equations and Inequalities: Concepts of equations and inequalities; solving simple inequalities (e.g., ax + b ≤ c) and representing solutions on a number line; graphs of linear equations (ax + by = c); solving simultaneous linear equations using substitution, elimination, or graphical methods; solving quadratic equations by factorisation; formulating linear equations to solve problems.

Geometry and Measurement

Here, the emphasis is on spatial reasoning and measurement, applying concepts to practical problems like designing structures or navigating maps.

• Congruence and Similarity: Congruent and similar figures; properties of similar triangles and polygons (equal corresponding angles, proportional corresponding sides); enlargement and reduction of plane figures; solving problems involving congruence and similarity.
• Pythagoras’ Theorem and Trigonometry: Applying Pythagoras’ theorem; identifying right-angled triangles from side lengths; using trigonometric ratios (sine, cosine, tangent) for acute angles to find unknown sides and angles in right-angled triangles.
• Mensuration: Volume and surface area calculations for pyramids, cones, and spheres.

Statistics and Probability

This strand develops skills in data interpretation and chance, useful for analyzing trends in everyday data like surveys or games.

• Data Handling and Analysis: Analyzing and interpreting dot diagrams, histograms, and stem-and-leaf diagrams; understanding purposes, advantages, disadvantages, and potential misinterpretations of these representations; measures of central tendency (mean, mode, median), including their uses and calculation of mean for grouped data.
• Probability: Probability as a measure of chance; calculating probabilities of single events, including listing all possible outcomes in simple situations.

The syllabus encourages integrated learning, where students connect math to other subjects or real life, and assessments include both theoretical understanding and application.

For G2 (mid-level), topics are similar but simplified—e.g., no full trigonometric ratios, limited to basic Pythagoras, and simpler algebraic fractions—while G1 focuses on foundational basics.

What happens in Sec 1 for Streaming in Sec 2 and Beyond

In Singapore’s secondary education system under Full Subject-Based Banding (FSBB), implemented fully since 2024, there are no rigid academic streams like the old Express, Normal (Academic), or Normal (Technical). Instead, students take subjects at one of three levels—G1 (least demanding, equivalent to old N(T)), G2 (mid-level, equivalent to old N(A)), or G3 (most demanding, equivalent to old Express)—based on their strengths, performance, and interests.

This allows for flexibility, with mixed-ability form classes. Adjustments to subject levels can occur at key points, such as from Secondary 1 (Sec 1) to Sec 2, or from Sec 2 to Sec 3 (upper secondary). Schools have some discretion in implementation, but guidelines are set by the Ministry of Education (MOE). Below, I’ll explain the process for level selection based on Sec 1 performance (for Sec 2) and then how Sec 2 performance influences Sec 3 options.

How Sec 1 Performance Determines G1, G2, G3 Levels for Sec 2

Students start Sec 1 with subject levels largely determined by their Primary School Leaving Examination (PSLE) scores, which assign them to Posting Groups (PG1, PG2, or PG3). These posting groups set the indicative starting level for most subjects. However, from the start of Sec 1, eligible students can opt for more demanding levels in core subjects (English Language (EL), Mother Tongue Language (MTL), Mathematics, and Science) based on specific PSLE Achievement Levels (ALs). For example:

• Students with indicative G2 level can take G3 if they scored PSLE Standard AL 5 or better.
• Students with indicative G1 level can take G2 or G3 if they scored PSLE Standard AL 5 or better, or G2 if AL 6 or Foundation AL A.

Here’s a table summarizing initial indicative levels based on PSLE scores:

PSLE Score Range	Posting Group	Indicative Starting Level for Most Subjects in Sec 1
4–20	PG3	G3
21–22	PG2 or PG3	G2 or G3
23–24	PG2	G2
25	PG1 or PG2	G1 or G2
26–30 (with AL 7 or better in EL and Math)	PG1	G1

During Sec 1, subject levels can be adjusted based on school performance (e.g., exams, assessments, and holistic teacher evaluations). This is not automatic—students may need to request or be recommended for changes, and schools assess readiness to ensure they can cope. Common criteria include:

• Upleveling (e.g., G2 to G3 or G1 to G2): Typically requires strong performance, such as 75% or above in the subject at the current level during Sec 1 assessments. For Humanities (Geography, History, Literature in English), upleveling from Sec 2 is based on Sec 1 aptitude, interest, and performance (e.g., strong in English for G1 to G2).
• Downleveling (e.g., G3 to G2): If a student struggles (e.g., below 50–60% or showing difficulty coping), schools may recommend a less demanding level to reduce load and build confidence. This is based on holistic assessment, including teacher feedback.

For MTL specifically, adjustments can be made if a student has difficulties, with schools allowing downleveling based on performance (e.g., from G3 to G2 if PSLE AL 6 or Foundation AL A). By the end of Sec 1, these adjustments finalize the levels for Sec 2.

Not all subjects are adjustable mid-year—core subjects have more flexibility, while others like Art or Design & Technology may follow school-specific policies.

How Sec 2 Performance Influences “Streaming” or Subject Options in Sec 3

Sec 2 is often considered a “transition year” (sometimes informally called the “streaming year” in reference to the old system), where performance shapes upper secondary (Sec 3–4/5) options.

Under FSBB, there are no fixed “courses” or streams—instead, students select subject combinations (typically 6–8 subjects) at G1, G2, or G3 levels for Sec 3, based on Sec 2 results, merit, interests, and school availability.

This selection happens at the end of Sec 2 through a subject allocation exercise, where students rank preferences, and allocation is merit-based (e.g., higher performers get priority).

The goal is to align with post-secondary pathways, such as Junior College (JC), Polytechnic, or Institute of Technical Education (ITE).

Key factors and criteria:

• Continuation at Current Level: Students generally continue subjects at the same level from Sec 2 to Sec 3 if they meet minimum passing requirements (e.g., at least 50% or Grade 5). They must meet “common academic requirements” set by the school to retain the level.
• Upleveling (e.g., G2 to G3): Possible for subjects where the student excels in Sec 2. Criteria are school-specific but often include scoring 75% or above in the G2-level exams for that subject. For example, a student taking G2 Math in Sec 2 could uplevel to G3 Math in Sec 3 with strong results. Schools may require bridging programs for uplevelers.
• Downleveling: If performance is weak (e.g., below passing thresholds), students may be required to drop to a lower level or not offer the subject.
• Overall Eligibility for All-G3 Subjects: To take all subjects at G3 in upper secondary, students need a gross ELMAB3 score (English + Math + Best 3 subjects, computed as if at G2 level, with at least Grade 5 in each) of 19 points or better based on Sec 2 results. This ensures they can handle the rigor.
• Subject Combination Options: Students must take compulsory subjects (EL, MTL, Humanities, Math, Science) plus electives. The mix of levels influences pathways:
• Mostly G3 (6–8 subjects): Prepares for GCE O-Level exams, leading to JC (needs L1R5 ≤20) or Polytechnic (ELR2B2 ≤26).
• Mix with G2/G3: Prepares for a combination of O-Level and N(A)-Level, suitable for Polytechnic or ITE Higher Nitec.
• Mostly G1/G2: Prepares for N(T)/N(A)-Level, leading to ITE Nitec or work-study diplomas.
  From 2028, some flexibility allows using one G2/G3 subject in post-secondary admission computations.

Schools provide guidance sessions for parents and students at the end of Sec 2 to discuss options. If a student’s Sec 2 performance doesn’t meet criteria for preferred levels, they may need to retake or adjust plans.
