SEC 3 IB MATHEMATICS
Take Year 3 Core and Advanced Mathematics in stride.
Year 3 of the IB-track Integrated Programme splits mathematics into two parallel courses: Core Mathematics, which extends the Year 2 syllabus into upper secondary depth; and Advanced Mathematics, which introduces A-Math content — algebraic fractions, polynomials, functions, exponentials, logarithms, and trigonometry — that lands students within reach of the IB Diploma.
What we cover (Year 3 Core + Advanced Mathematics)
Year 3 IB-track students take two mathematics courses in parallel. Core Mathematics covers simultaneous equations, quadratics, indices, surds, logarithms, trigonometry (sine and cosine rule, area, bearings, 3D problems), linear inequalities, theory of quadratic equations, coordinate geometry, graphs of functions, and mensuration of pyramids, cones, and spheres. Advanced Mathematics covers algebraic fractions, polynomials, partial fractions, functions (composite, inverse, modulus, transformations), exponentials, logarithms, basic and intermediate trigonometry. Our class teaches the Year 3 Core and Advanced curriculum used at local IB schools.
Year 3 Core Mathematics
Simultaneous Equations: linear–linear and linear–non-linear in two unknowns
Solutions to Quadratic Equations: completing the square, quadratic formula, graphs and curve sketching
Indices, Surds, and Logarithms: laws of indices, surds, exponential equations
Solutions of a Triangle: trigonometric ratios for acute and obtuse angles, sine and cosine rule, area, bearings, 3D problems
Linear Inequalities: properties, solving in one variable, word problems
Theory of Quadratic Equations, Functions, and Inequalities: sum and product of roots, quadratic inequalities, discriminant and nature of roots
Coordinate Geometry: midpoint, distance, gradient, equation of a straight line, collinear points, parallel and perpendicular lines, perpendicular bisectors, area of rectilinear figures
Graphs of Functions: cubic, reciprocal, exponential; graphical solutions
Mensuration: pyramids, cones, spheres
Year 3 Advanced Mathematics
Algebraic Fractions: simplifying and solving
Polynomials: identities, long division, remainder and factor theorems, cubic equations
Partial Fractions: linear, repeated linear, and irreducible quadratic factors
Functions: relations and functions, composite, inverse, absolute-valued functions, transformations of graphs
Exponentials and Logarithms: properties and laws of logarithms, logarithmic and exponential equations, graphs and applications
Basic Trigonometry: basic angles, simple trigonometric equations, graphs of sine, cosine, and tangent
Intermediate Trigonometry: proving identities, solving trigonometric equations
The Year 3 Core and Advanced Mathematics syllabus is consistent across local IB-track schools.
Common challenges for Year 3 IB students
Year 3 introduces a step change — two mathematics courses in parallel — and the depth jumps sharply. Students often share these pressure points:
Two courses, two assessment streams
Core and Advanced are graded separately, with distinct papers, distinct topics, and distinct expectations. Students who try to lump them together often underperform on both.
Advanced Mathematics introduces A-Math depth quickly
Polynomials, partial fractions, function transformations, and trigonometric identities arrive in rapid sequence. Students need fluent algebra and a clear mental model of functions to keep up.
Coordinate geometry and trigonometry get layered
Sine rule, cosine rule, 3D problems, perpendicular bisectors, and gradients all show up in mixed-topic problems. Students need to switch context fluidly.
IB Diploma is now visible on the horizon
Year 3 is when the IB pathway becomes concrete. Students who treat Year 3 as a holding year often arrive in Year 4 short of the foundation they need for AA HL or AI HL.
How DeepThink helps Sec 3 IB students
Our Sec 3 IB class is built around the reality of two mathematics courses running in parallel:
Teach Core and Advanced as separate disciplines
Each course has its own pacing, its own assessment style, and its own conceptual demands. We treat them that way — not as one bigger maths class.
Built around the Year 3 IB-track scheme
The Year 3 Core and Advanced Mathematics syllabus is broadly consistent across local IB schools. Our class teaches that scope directly.
Build the function and algebra fluency Advanced demands
Composite functions, inverse functions, polynomials, and trigonometric identities are all built on flexible algebra. We make sure that fluency is there before diving into the harder topics.
Anchor reasoning, not just procedure
IB-track schools assess understanding. We teach students to explain identities and proofs, not just compute.
Year 3 is the leap into IB-level mathematics. We make sure students land it cleanly.

Decision support
When Secondary 3 IB support is the right fit
These are the situations where extra support tends to make the biggest difference.
Two courses, two assessment streams
Core and Advanced are graded separately, with distinct papers, distinct topics, and distinct expectations. Students who try to lump them together often underperform on both.
Advanced Mathematics introduces A-Math depth quickly
Polynomials, partial fractions, function transformations, and trigonometric identities arrive in rapid sequence. Students need fluent algebra and a clear mental model of functions to keep up.
Coordinate geometry and trigonometry get layered
Sine rule, cosine rule, 3D problems, perpendicular bisectors, and gradients all show up in mixed-topic problems. Students need to switch context fluidly.
If any of these patterns sound familiar, this is likely the right level of support for your child — a trial class is a good next step.
Frequently asked questions
Clear answers for parents
Who is Secondary 3 IB Math tuition for?
Secondary 3 IB students who need clear weekly structure and targeted practice.
What does weekly Secondary 3 IB support include?
Students attend a 1.5-hour live online class each week and then work through targeted online practice with instant marking and solutions between lessons.
Which syllabus or exam does this Secondary 3 IB page cover?
Year 3 IB-track students take two mathematics courses in parallel. Core Mathematics covers simultaneous equations, quadratics, indices, surds, logarithms, trigonometry (sine and cosine rule, area, bearings, 3D problems), linear inequalities, theory of quadratic equations, coordinate geometry, graphs of functions, and mensuration of pyramids, cones, and spheres. Advanced Mathematics covers algebraic fractions, polynomials, partial fractions, functions (composite, inverse, modulus, transformations), exponentials, logarithms, basic and intermediate trigonometry. Our class teaches the Year 3 Core and Advanced curriculum used at local IB schools.
Can families start with a trial class first?
Yes. Families can start with a trial class to see the teaching pace, structure, and level fit before committing.
How do parents know what to work on next?
We keep parents informed on what was covered and where their child should focus. If we spot persistent gaps, we flag them early — not just before exams.
