Is IGCSE Additional Maths worth it?

What it is

Both are a second maths qualification at IGCSE level. Cambridge says the course stretches more able candidates and gives a smooth transition to Cambridge International AS & A Level Mathematics. Pearson says it extends the further pure maths in International GCSE Mathematics A (Higher tier) and Mathematics B, and gives a solid basis for AS and A Level Mathematics or equivalent courses.

Both assume you know IGCSE Maths already. They add functions, quadratics, polynomials, logarithms and exponentials, coordinate geometry, circular measure, trigonometry, series and the binomial expansion, vectors, differentiation, integration and kinematics, several of which come up again early in A Level Maths.

Reasons to take it

• You meet calculus, logarithms and harder trigonometry before A Level or the IB, so the first year of A Level feels less new. See what carries over.
• It stretches students who find IGCSE Maths comfortable, with longer, multi-step problems.
• It gives a separate grade that shows strength in maths beyond the core course.

Things to weigh up

• Time: two more 2-hour papers and a full course to learn, often in the same year as your other IGCSEs.
• Your IGCSE Maths grade matters more for most next steps. If Additional Maths would take time away from it, think carefully.
• Entry: your school has to offer it (or an exam centre has to enter you). Ask early.
• Requirements: we do not know of a general rule that sixth forms, colleges or universities require it; check the entry requirements of the places you are applying to.

0606 or 4PM1?

Usually your school decides, because it follows one board. The main differences:

• Calculator: 0606 Paper 1 is non-calculator; both 4PM1 papers allow a calculator.
• Grades: 0606 is graded A* to E; 4PM1 is graded 9 to 4, with 3 allowed.
• Content: 0606 includes functions, circles and permutations and combinations; 4PM1 includes the sum and product of roots, the addition formulae and volumes of revolution.

A quick self-check

Try these three topic pages. If the worked examples make sense after a careful read, you are likely ready for the course:

• Quadratics (completing the square and the discriminant)
• Logarithms and exponentials
• Differentiation
