Number Systems
Lay the foundation of mathematics by exploring the structure of numbers — from natural numbers and integers to rational, irrational, and real numbers. Students learn number operations, factors, multiples, prime numbers, and standard form as specified in the ZIMSEC syllabus.
- 1.1Natural Numbers, Integers, and the Number LineIncluded
- 1.2Fractions, Decimals, and PercentagesIncluded
- 1.3Factors, Multiples, and Prime NumbersIncluded
- 1.4Powers, Roots, and Standard FormIncluded
Set Language and Notation
Introduce the language of sets — defining sets, membership, subsets, unions, intersections, and complements — and apply Venn diagrams to solve both abstract and real-life problems as required by ZIMSEC.
- 2.1Defining Sets and Set NotationIncluded
- 2.2Union, Intersection, and ComplementIncluded
- 2.3Solving Problems with Venn DiagramsIncluded
Financial Mathematics
Apply mathematics to real-world financial situations including profit and loss, simple and compound interest, hire purchase, exchange rates, and taxation — all examined contexts in the ZIMSEC O-Level paper.
- 3.1Profit, Loss, and Percentage ChangeIncluded
- 3.2Simple and Compound InterestIncluded
- 3.3Hire Purchase, Tax, and Exchange RatesIncluded
Measures and Mensuration
Master the measurement of length, mass, time, temperature, and capacity using correct units and conversions, and calculate perimeter, area, surface area, and volume of standard 2D and 3D shapes.
- 4.1Units of Measurement and ConversionIncluded
- 4.2Perimeter and Area of 2D ShapesIncluded
- 4.3Surface Area and Volume of 3D ShapesIncluded
Graphs of Linear Functions
Plot and interpret straight-line graphs, find gradients and intercepts, determine equations of lines, and solve simultaneous equations graphically — core skills for ZIMSEC Paper 2.
- 5.1The Cartesian Plane and Plotting PointsIncluded
- 5.2Gradient, Intercepts, and Equation of a LineIncluded
- 5.3Graphical Solution of Simultaneous EquationsIncluded
Algebra
Build strong algebraic skills from simplifying expressions and solving linear equations to factorisation, quadratic equations, and inequalities — forming the backbone of the ZIMSEC O-Level paper.
- 6.1Algebraic Expressions and SimplificationIncluded
- 6.2Solving Linear Equations and InequalitiesIncluded
- 6.3FactorisationIncluded
- 6.4Quadratic EquationsIncluded
Geometry
Investigate angle properties, triangle congruence and similarity, circle theorems, constructions, and transformations — all key elements of the ZIMSEC Geometry syllabus for Forms 2 to 4.
- 7.1Angles and Parallel LinesIncluded
- 7.2Triangles, Congruence, and SimilarityIncluded
- 7.3Circle TheoremsIncluded
- 7.4Geometric Constructions and TransformationsIncluded
Statistics and Probability
Collect, organise, and display data in various forms; calculate and interpret measures of central tendency and spread; and apply theoretical and experimental probability — all as required by ZIMSEC.
- 8.1Data Collection and DisplayIncluded
- 8.2Measures of Central Tendency and SpreadIncluded
- 8.3ProbabilityIncluded
Matrices
Introduce matrix notation, perform matrix arithmetic (addition, subtraction, multiplication), find determinants and inverses of 2×2 matrices, and use matrices to solve simultaneous equations.
- 9.1Matrix Notation and Basic OperationsIncluded
- 9.2Matrix MultiplicationIncluded
- 9.3Determinants, Inverses, and Solving EquationsIncluded
Trigonometry

Renstay College
Hello and welcome! I'm so glad you've chosen to take your Mathematics journey seriously — and I'm here to walk every step of it with you. I've spent years teaching ZIMSEC Mathematics, watching students transform from anxious, unsure learners into confident exam candidates, and I've built this course around exactly what works in that process. I know where students get stuck — whether it's factorising quadratics, constructing geometric proofs, or making sense of vectors for the first time — and I've designed each lesson to address those moments head-on. My teaching style is straightforward and practical: I'll always show you the concept, walk you through a worked example, and then give you the chance to try it yourself. Mathematics is not a spectator sport — you have to do it to learn it, and that's what we'll do together. Whether you're in Form 1 taking your first steps or in Form 4 preparing for the big exam, I'm committed to helping you get the grade you deserve. Let's get to work!
