# What Comes After IGCSE Maths?
> **Answer.** The usual next step is A Level Mathematics, and Cambridge's 9709 syllabus assumes you have covered the 0580 Extended content — so a Core candidate has a gap to close first. The alternatives are IB Diploma mathematics, which is two separate subjects rather than one, a national route such as Intermediate, or AP Calculus in a US-pattern school.
## The line that settles the first route
Cambridge's AS and A Level Mathematics syllabus states its prior knowledge in one sentence: knowledge of the content of Cambridge IGCSE Mathematics 0580 Extended, or Cambridge International O Level 4024/4029, is assumed.
Read that as an instruction rather than a suggestion. Paper 1 opens on quadratics, functions, coordinate geometry and trigonometry, all treated as tools already in hand. A student who sat the Core route has not met several of them, and the course will not stop to teach them.
This is not a verdict on whether a Core candidate can do A Level Mathematics. Plenty can. It is a statement about when the extra work happens: deliberately, in the months before the course, or painfully, in October when everyone else is already moving.
## A Level Mathematics: the combination that traps people
Cambridge A Level Mathematics is four components. Everyone takes Paper 1 Pure Mathematics 1 and Paper 3 Pure Mathematics 3. Then either Paper 4 Mechanics with Paper 5 Probability & Statistics 1, or Paper 5 with Paper 6 Probability & Statistics 2. Paper 4 and Paper 6 cannot be combined, because Paper 6 depends on Paper 5.
AS Level is two components, and here is the part worth reading twice. Paper 1 can be paired with Paper 2 Pure Mathematics 2, with Paper 4, or with Paper 5. But the pure-only route — Papers 1 and 2 — is available at AS Level only and cannot be carried forward to complete the A Level.
It is the route that looks safest to a student who prefers pure mathematics, and it is the one that dead-ends. If the A Level is the destination, the AS year has to be Paper 1 with Paper 4 or Paper 5. Further Mathematics, if it is in view, sits on top of the A Level rather than beside it.
## IB mathematics is two subjects, not two tiers
The IB Diploma offers Mathematics: analysis and approaches and Mathematics: applications and interpretation, each at standard and higher level. They are different courses with different emphases — one built around proof and algebraic argument, the other around modelling and interpreting data — not an easier and a harder version of one syllabus.
That matters at the point of application. Degree courses that require higher level mathematics frequently name which of the two they mean, and a student who chose on the basis of enjoyment in Year 11 can find the wrong one on their transcript in Year 13.
Check the requirements of two or three specific degree courses before choosing. Ten minutes on university course pages resolves this permanently.
## The national and American routes
Inside Pakistan, the Intermediate — FSc pre-engineering or pre-medical, or ICS — is the mainstream continuation, with the IBCC handling equivalence between the international and national systems. It is the right route for a student whose destination is a Pakistani university, and it is chosen far more often on cost and proximity than the international-school conversation admits.
In a US-pattern school, IGCSE is followed by Grades 11 and 12, typically Precalculus and then AP Calculus AB or BC. This is the route to plan for if the destination is a US university, because it produces the four-year transcript those applications assume.
None of these is a lesser option. They are answers to different questions about where the student is going, and the mistake is picking one for reasons of prestige rather than direction.
## What to do in the months between
IGCSE results for the June series arrive in August, and courses start in August or September. The useful window is therefore the summer before results, not the fortnight after them — which is why the work has to be planned in June rather than considered in late August.
For a student heading to A Level Mathematics from Core, or from Extended with a modest grade, the list is short and specific.
- Expanding and factorising quadratics, including where the coefficient of x squared is not 1
- The quadratic formula, the discriminant, and completing the square
- Index laws with negative and fractional indices, and surds
- Rearranging formulae where the subject appears more than once
- Simultaneous equations, including one linear and one quadratic
- Straight-line geometry: gradients, midpoints, parallel and perpendicular lines
- The sine rule, the cosine rule, and exact values for common angles
## What changes the answer
- If you took the Core route, the prior knowledge A Level assumes is not knowledge you have yet, and that has to be dealt with before the course starts.
- If a specific degree subject is already in view, its published requirements decide between the routes more reliably than any general advice.
- If your school offers only one of these routes, the real choice is between that route and changing school, which is a different decision entirely.
- If mathematics is not going to feature after 18, a course that keeps quantitative skills alive may serve better than the hardest option available.
## Questions
### Can I take A Level Maths after the Core route at IGCSE?
It is possible, but you start with a genuine content gap because 9709 assumes the Extended syllabus. Name the gap using the topic list above, work through it in the summer, and tell the new teacher on day one. What does not work is hoping it goes unnoticed.
### Do I need Further Mathematics for an engineering degree?
It varies, and the only reliable check is the entry requirements of the specific courses you are interested in. Many engineering courses ask for mathematics and physics and treat further mathematics as desirable rather than required; some strongly prefer it. Look at two or three universities before deciding.
### How long is the gap between IGCSE results and starting A Level?
For the June series, results land in August and most courses begin within weeks. That is why bridging work belongs to the summer before results rather than the days after them. Schools that set summer transition work are doing something useful with that window, not adding busywork.
### Is it worth taking AS Level only?
It can be, as a standalone qualification for a student who wants mathematics on the record without two full years of it. Just choose the combination that keeps the A Level reachable — Paper 1 with Paper 4 or Paper 5 — rather than the pure-only route, which cannot be carried forward.
