Last updated: 2026-07-20
Sitting the exam in 2027? Use K310. Sitting in 2026? Keep using the current 4052 syllabus and your school materials.
Check the current K310 syllabus for the authoritative learning outcomes, paper format, and permitted formula information. This hub does not carry 2026 assessment details into the 2027 track.
01
N1
Build reliable exact and approximate calculation, number-property, standard-form, and estimation checks.
N2
Translate ratios, scales, direct comparisons, and proportional change into a consistent working method.
N3
Handle percentage change, reverse percentage, repeated change, and financial contexts without mixing the base quantity.
N4
Connect units, average rate, speed, distance, and time while checking whether a rate is constant or changing.
N5
Manipulate expressions, factorise, change the subject, and substitute with brackets and units kept visible.
N6
Read, sketch, and interpret relationships from equations, tables, and graphs, including gradient and intercept meaning.
N7
Choose an algebraic or graphical route, preserve inequality direction, and check solutions in the original condition.
N8
Translate set notation, Venn diagrams, complements, intersections, and unions without double counting.
N9
Use matrix notation and operations only within the current K310 scope, with dimensions checked before calculation.
02
G1
Use angle facts and polygon properties with reasons stated rather than relying on diagram appearance.
G2
Select the correct test or scale factor, then distinguish length, area, and volume relationships.
G3
Match each circle configuration to the relevant theorem and state the theorem used.
G4
Choose Pythagoras, sine, cosine, tangent, or a non-right-triangle method from the information given.
G5
Break composite figures into known shapes, keep units consistent, and round only at the final step.
G6
Connect gradient, distance, midpoint, and line equations to the geometry shown.
G7
Express routes with consistent direction, simplify vector relations, and justify collinearity or parallelism from the result.
03
S1
Choose suitable summaries and representations, then interpret spread, centre, trends, and possible limitations.
S2
Define the sample space, use complements or combined events carefully, and check that final probabilities are plausible.
Official curriculum source: SEAB 2027 SEC G3 Mathematics K310 syllabus. Checked 15 July 2026. Recheck codes, outcomes and assessment details before annual updates.
The focus lines are Eclat revision guidance. They are not quoted syllabus text and do not replace the official learning outcomes.
This hub maps the official 2027 SEC G3 Mathematics K310 top-level topics. The linked SEAB syllabus remains authoritative for every assessable learning outcome and paper detail.
O-Level is still familiar reader language and 4052 is the 2026-and-earlier reference code. Students sitting in 2027 should use K310, while 2026 candidates must follow their current legacy syllabus and school instructions.
Only as a national comparison. IP schools control their own sequence, depth, and assessment scope, so IP students should use the separate IP route and follow current school materials first.
