About Mathematics (OL)

Mathematics is a fundamental subject at both O/L and A/L levels in Sri Lanka. At O/L, it tests core arithmetic, algebra, and geometry skills. At A/L, Combined Mathematics is one of the most demanding subjects, covering advanced pure and applied mathematics required for engineering and science degrees.

What You Study in Mathematics

Algebra — equations, inequalities, polynomials, matrices
Calculus — differentiation, integration, differential equations
Trigonometry — identities, equations, applications
Coordinate Geometry — lines, circles, conics
Mechanics — kinematics, dynamics, statics (Applied Maths)
Statistics — probability, distributions, hypothesis testing

Examination Structure

Paper I (Pure Mathematics)3 hours

10 compulsory questions covering algebra, calculus, trigonometry, and coordinate geometry.

Paper II (Applied Mathematics)3 hours

Questions on Mechanics and Statistics. Students answer questions from both sections.

Study Tips for Mathematics

1Build algebra foundations first — weak algebra affects every other topic
2Practice differentiation and integration daily until automatic
3Work through at least 2 full past papers per week under exam conditions
4Learn to show all working clearly — method marks are crucial
5Focus on Mechanics vectors and kinematics early in Applied Maths
6Use the official NIE textbook as the primary reference

Frequently Asked Questions

View all FAQs

What is the difference between O/L Maths and A/L Combined Maths?

O/L Mathematics covers foundational topics for all students. A/L Combined Mathematics is significantly more advanced, covering university-level pure mathematics (calculus, complex numbers, vectors) and applied mathematics (mechanics, statistics). It is one of the most challenging A/L subjects.

Is a calculator allowed in A/L Combined Mathematics?

Yes, non-programmable scientific calculators are permitted in both A/L Combined Mathematics papers. Students should be proficient with logarithms, trigonometric functions, and statistical calculations.

How should I prepare for O/L Mathematics?

Start with the past papers from the last 5 years, practice Paper I (structured) and Paper II (essay) separately, and focus on topics that appear repeatedly: algebra, geometry theorems, and mensuration calculations.
