PCME/BCME– JC Subject Combinations
JC subject combinations are commonly abbreviated using the initials of H2 subjects. The two most popular Science stream combinations are PCME (Physics, Chemistry, Math, Economics) and BCME (Biology, Chemistry, Math, Economics). Arts stream combinations include HELM (History, Economics, Literature, Math) and GELM (Geography, Economics, Literature, Math). Students typically take 3 H2 + 1 H1 from their combination, plus compulsory H1 General Paper (GP) and Project Work (PW). Choosing the right combination depends on university course prerequisites — for example, Medicine requires H2 Chemistry, while Engineering typically requires H2 Math and H2 Physics.
E-Maths– Elementary Mathematics
Elementary Mathematics (E-Maths, also written as E Math, EMath, or colloquially Elem Maths) is a compulsory upper secondary mathematics subject in Singapore covering algebra, geometry, trigonometry, statistics, and probability. It focuses on practical mathematical applications for everyday life and provides essential quantitative skills. E-Maths is a prerequisite for most post-secondary courses and polytechnic programmes. Under Full SBB, E-Maths can be taken at G3 or G2 levels, assessed via national examinations (GCE O-Level for current cohorts; SEC under Full SBB).
A-Maths– Additional Mathematics
Additional Mathematics (A-Maths, also written as A Math, AMath, or colloquially Add Maths) is an elective upper secondary mathematics subject in Singapore covering advanced topics including calculus, differentiation, integration, trigonometric identities, logarithms, and coordinate geometry. A-Maths develops abstract reasoning skills and is strongly recommended for students pursuing Science, Engineering, or Mathematics streams in Junior College — H2 Mathematics assumes A-Maths knowledge. Under Full SBB, A-Maths is available at G3 or G2 levels, assessed via national examinations (GCE O-Level for current cohorts; SEC under Full SBB).
H1– H1 Subject
H1 (Higher 1) subjects in Singapore Junior Colleges represent a foundational level of study, requiring half the curriculum time of H2 subjects. Students typically take one or two H1 subjects alongside their H2 subjects. H1 subjects contribute to the A-Level aggregate score.
H2– H2 Subject
H2 (Higher 2) subjects in Singapore Junior Colleges represent an in-depth level of study, forming the core of A-Level preparation. Students take three or four H2 subjects. H2 subjects are prerequisites for related university courses (e.g., H2 Chemistry for Medicine).
GP– General Paper
General Paper (GP) is a compulsory H1 subject for all Junior College students in Singapore. It develops critical thinking, argumentation, and essay writing skills through analysis of current affairs, social issues, and global topics. GP is assessed through essay writing and comprehension, and contributes to university admission rank points. Strong GP performance demonstrates analytical and communication abilities valued by universities.
HCL– Higher Chinese
Higher Chinese Language (HCL, also called Higher Mother Tongue or HMT / HMTL for Chinese) is an advanced Mother Tongue subject in Singapore covering the same topics as standard Chinese but at greater depth, with more complex texts and higher writing expectations. HCL students typically sit for the standard Chinese O-Level in Secondary 3, then the Higher Chinese O-Level in Secondary 4. Achieving a D7 or better in Higher Chinese O-Level qualifies students for Mother Tongue exemption at A-Level. As of 2026, eligibility for Higher Mother Tongue in Secondary 1 is based solely on PSLE Mother Tongue performance (AL1 or AL2 in MTL, or Distinction/Merit in HMTL at PSLE), no longer requiring a specific overall PSLE score.
MTL B– Mother Tongue Language B Syllabus
MTL B Syllabus is a less demanding Mother Tongue option for students who struggle significantly with the standard curriculum. Students may be offered MTL B if they scored AL7-8 in PSLE MTL, or D7-F9 at O-Level. Important: MTL B is not counted in the L1R5 aggregate for post-secondary admission, and students must still pass MTL B for local university admission. MTL exemption should only be considered as a last resort for exceptional circumstances.
Phy– Physics
Physics is a natural science subject in Singapore secondary schools covering mechanics, thermal physics, waves, electricity, magnetism, and modern physics. It is offered as Pure Physics at O-Level or as Combined Physics within Combined Science (Physics/Chemistry or Physics/Biology). Pure Physics is typically required for engineering, computing, and physical science courses at university. Under Full SBB, Physics can be taken at G3 or G2 levels.
Chem– Chemistry
Chemistry is a natural science subject in Singapore secondary schools covering atomic structure, chemical bonding, acids and bases, redox reactions, organic chemistry, and energetics. It is offered as Pure Chemistry at O-Level or as Combined Chemistry within Combined Science. Chemistry is the most common Pure Science combination partner and is required for medicine, pharmacy, and many science courses at university. Under Full SBB, Chemistry can be taken at G3 or G2 levels.
Bio– Biology
Biology is a natural science subject in Singapore secondary schools covering cell biology, genetics, ecology, human physiology, and molecular biology. It is offered as Pure Biology at O-Level or as Combined Biology within Combined Science. Pure Biology is typically required for medicine, dentistry, and life science courses at university. Under Full SBB, Biology can be taken at G3 or G2 levels.
Geog– Geography
Geography is a humanities subject in Singapore secondary schools and Junior Colleges, covering physical and human geography, environmental issues, and spatial analysis. At O-Level, Geography can be taken as a full elective or as part of Combined Humanities. At A-Level, it is offered as H1 or H2 Geography. Under Full SBB, Geography can be taken at G3 or G2 levels.
Hist– History
History is a humanities subject in Singapore secondary schools and Junior Colleges, covering Southeast Asian history, modern world history, and historical investigation skills. At O-Level, History can be taken as a full elective or as part of Combined Humanities. At A-Level, it is offered as H1 or H2 History. Under Full SBB, History can be taken at G3 or G2 levels.
Lit– English Literature
English Literature (commonly abbreviated Lit) is a humanities subject in Singapore secondary schools and Junior Colleges, covering poetry, prose, and drama analysis. At O-Level, Literature can be taken as a full elective or as part of Combined Humanities. At A-Level, it is offered as H1 or H2 Literature in English. Under Full SBB, Literature can be taken at G3 or G2 levels.
SS– Social Studies
Social Studies (SS) is a compulsory humanities subject in Singapore secondary schools, forming the core component of Combined Humanities at O-Level. SS covers three main themes: understanding Singapore's governance, appreciating diversity in a multi-ethnic society, and examining globalisation and its impact. Assessment includes Source-Based Questions (SBQ) and Structured Essay Questions (SEQ). All secondary students take SS paired with an elective — either History, Geography, or Literature — as Combined Humanities. SS is not offered as a standalone O-Level subject.
Combined Humanities
Combined Humanities is a compulsory O-Level subject in Singapore that pairs Social Studies (SS) with one elective humanities subject — Elective History, Elective Geography, or Elective Literature. All secondary students must take Combined Humanities, making it a universal component of the O-Level or SEC examination. The SS component accounts for roughly half the assessment, with the elective component making up the rest. Combined Humanities counts towards the L1R5 aggregate for JC admission. Students who wish to study humanities in greater depth can additionally take a full (pure) History, Geography, or Literature subject.
EL– English
English (also referred to as English Language or EL) is a core subject at all levels in Singapore, from Primary 1 through Junior College. It covers oral communication, reading comprehension (compre), composition writing (compo), grammar, and vocabulary. At primary level, key components include grammar cloze, comprehension cloze, synthesis and transformation, and continuous writing. At O-Level, English Language (Syllabus 1184) assesses situational writing, continuous writing, and comprehension. A pass in English is required for admission to Junior College (L1R5 / L1R4) and local universities.
Chi– Chinese
Chinese (Mandarin) is the most common Mother Tongue Language subject in Singapore, studied from Primary 1 through secondary education. It covers oral communication, reading comprehension, composition writing, and language use. At primary level, it builds foundational literacy. At secondary level, students take Chinese at O-Level, or Higher Chinese (HCL) for advanced learners. Achieving a pass in Chinese or Higher Chinese O-Level fulfils the Mother Tongue requirement for local university admission.
MTL– Mother Tongue Language
Mother Tongue Language (MTL) is a compulsory subject in Singapore schools. The three options are Chinese (Mandarin), Malay, and Tamil, assigned based on the student's registered ethnicity. MTL is studied from Primary 1 through secondary education and assessed at PSLE and O-Level. A pass in MTL or Higher Mother Tongue at O-Level is required for local university admission. Students who struggle significantly may be offered MTL B Syllabus as an alternative.
Problem Sums
Problem sums is the Singapore English term for mathematical word problems that require multi-step reasoning and application of concepts. In the MOE primary mathematics syllabus, problem sums test students' ability to interpret real-world scenarios, identify the relevant mathematical operations, and work through solutions systematically. Problem sums form a significant portion of the PSLE Mathematics paper and are where most students lose marks. Common strategies include model drawing (bar model method), working backwards, and making systematic lists.
Heuristics– Heuristics for Problem-Solving
Heuristics are systematic problem-solving strategies taught in the Singapore MOE mathematics syllabus from Primary 1 to Primary 6. The MOE identifies specific heuristics that students should master, including: drawing a model or diagram, looking for patterns, working backwards, making a systematic list, guess and check, simplifying the problem, making suppositions (assumptions), and restating the problem. Heuristics are tested extensively in PSLE Mathematics and are essential for tackling non-routine problem sums.
Bar Model– Bar Model Method
The Bar Model Method (also called model drawing or the Singapore model method) is a visual problem-solving approach central to Singapore Mathematics. Students use rectangular bars to represent known and unknown quantities, making abstract mathematical relationships concrete and visible. The bar model is used for addition, subtraction, multiplication, division, fractions, ratios, and percentages. It is taught from Primary 1 and is a key strategy for solving PSLE problem sums. The Singapore bar model method has been adopted internationally as part of Singapore Math curricula.
Econs– Economics
Economics is an A-Level subject offered at H1 and H2 levels in Singapore Junior Colleges. It covers microeconomics (market forces, market failure, government intervention) and macroeconomics (national income, inflation, unemployment, international trade). H2 Economics requires deeper analysis and more rigorous essay writing than H1. Economics is one of the most popular JC subject choices and is commonly abbreviated as Econs.
Compo– Composition Writing
Composition writing (commonly called compo by Singapore students and parents) is a key component of English and Chinese Language examinations at all levels. For PSLE, composition accounts for a significant portion of Paper 1. Students must master narrative structures (hook, rising action, climax, resolution), descriptive writing techniques, and time management. Studying model compositions (model compo) — well-written examples that demonstrate good technique — is a common revision strategy. At O-Level, composition evolves into situational writing and continuous writing. Chinese composition follows similar structures but requires proficiency in idioms and essay conventions specific to the Chinese paper.
Compre– Comprehension
Comprehension (commonly called compre by Singapore students and parents) is a key examination component in English and Chinese Language at all levels. It tests reading skills including inference, vocabulary in context, summary writing, and information retrieval. At PSLE level, comprehension includes visual text, grammar cloze, comprehension cloze, and open-ended questions. At O-Level, comprehension passages become longer and questions require more sophisticated analysis. Comprehension strategies include active reading, highlighting key points, identifying question types, and time management.
Cloze Passage
A cloze passage is a text with blanks that students must fill in, testing grammar, vocabulary, and contextual understanding. In Singapore examinations, there are three main types: grammar cloze (fill in with the correct grammatical form), vocabulary cloze (choose the best word from given options), and comprehension cloze (fill in based on understanding of the passage). Cloze passages appear in PSLE English Paper 2, O-Level English, and Chinese Language papers at all levels. Strategies include reading the full passage first, using context clues, checking grammatical agreement, and eliminating unlikely options.
S&T– Synthesis and Transformation
Synthesis and Transformation is an English grammar component tested in Singapore primary and secondary school examinations. In synthesis questions, students combine two or more sentences into a single sentence using conjunctions, relative clauses, or other grammatical structures. In transformation questions, students rewrite sentences while preserving the original meaning, often changing voice (active to passive), tense, or sentence type. Synthesis and Transformation is a common section in PSLE English Paper 2 and O-Level English.
