Is IB Maths AA HL hard?
An honest answer from maths teachers, with the facts from the IB and three pairs of questions: the same idea at SL and at HL, so you can see the step for yourself.
The short answer
Yes, for most students AA HL is hard work. In our experience it is not one impossible topic that makes it hard: it is the amount (240 teaching hours against 150 at SL), the algebra you must do without a calculator, and long questions that do not tell you which method to use.
If your algebra is secure now and you like working on a problem you have not seen before, AA HL is very manageable. If you need maths HL for your university course, the extra work is worth it; if you don't, SL may be the better choice.
Side by side
| AA SL | AA HL | |
|---|---|---|
| Teaching hours (current and revised course) | 150 | 240 |
| Exams now | Paper 1 and Paper 2, 1 hour 30 minutes each | Paper 1 and Paper 2, 2 hours each (110 marks each), plus Paper 3, 1 hour 15 minutes |
| Exams in the revised course (first exams May 2029) | Paper 1 and Paper 2, 75 marks each | Paper 1 and Paper 2, 100 marks each, plus Paper 3, 1 hour |
| No-calculator paper (current and revised course) | Paper 1 | Paper 1 |
| Topics only at HL (revised course) | None of these | Complex numbers, vectors, differential equations, Maclaurin series |
| Internal assessment | The exploration, 20% | The exploration, 20%, same criteria |
Students who start the Diploma before August 2027 take the current course; the revised course starts in August 2027 (first exams May 2029).
What students find hard
- Algebra without a calculator. AA Paper 1 is the no-calculator paper, in the current course and the revised one. At HL the algebra is longer, and one slip early on costs the marks that follow.
- Questions that don't name the method. HL questions often join two or three topics and leave you to choose the route. Practising unfamiliar questions matters more than learning more methods.
- Abstract topics. Proof, complex numbers and the further calculus are less about calculating an answer and more about explaining why it is true.
- Paper 3. An HL-only paper of long, extended problems. In our experience it rewards students who stay calm with an idea they have not met in that form.
- The amount. There is simply more: more topics and more hours, alongside five other Diploma subjects, your IA, TOK and the extended essay.
This is our view from teaching these courses, not a statistic. We don't quote pass rates here: the exam boards publish their own results each year.
Try it: questions side by side
Each pair takes the same idea at two levels. Try both before you open the answers.
AA SL
An arithmetic sequence has first term 7 and common difference 4. Find the sum of the first 20 terms.
Show the answer
Answer: 900
- S20 = (20/2)(2 × 7 + 19 × 4) = 10 × 90 = 900.
AA HL
Prove by induction that 1 × 2 + 2 × 3 + … + n(n + 1) = n(n + 1)(n + 2)/3 for every positive integer n.
Show the answer
Answer: A proof in four steps: base case, assumption, inductive step, conclusion.
- n = 1: the left side is 1 × 2 = 2 and the right side is (1 × 2 × 3)/3 = 2, so it is true for n = 1.
- Assume it is true for n = k: the sum to k(k + 1) is k(k + 1)(k + 2)/3.
- Add the next term (k + 1)(k + 2): k(k + 1)(k + 2)/3 + (k + 1)(k + 2) = (k + 1)(k + 2)(k + 3)/3, which is the formula with n = k + 1.
- It is true for n = 1, and if it is true for n = k it is true for n = k + 1, so it is true for every positive integer n.
AA SL
Find the exact value of ∫02 (6x2 − 4x + 3) dx.
Show the answer
Answer: 14
- An antiderivative is 2x3 − 2x2 + 3x.
- At x = 2: 16 − 8 + 6 = 14. At x = 0: 0. So the value is 14.
AA HL
Find ∫ x e2x dx.
Show the answer
Answer: ¼e2x(2x − 1) + C
- Integrate by parts with u = x and dv/dx = e2x, so du/dx = 1 and v = ½e2x.
- ∫ x e2x dx = ½x e2x − ∫ ½e2x dx = ½x e2x − ¼e2x + C = ¼e2x(2x − 1) + C.
AA SL
Find the value of k for which the equation x2 − 6x + k = 0 has two equal roots.
Show the answer
Answer: k = 9
- Equal roots: discriminant = 0, so 36 − 4k = 0 and k = 9.
AA HL
Solve z2 − 6z + 13 = 0, giving each root in the form a + bi, and find the modulus of each root.
Show the answer
Answer: z = 3 + 2i or z = 3 − 2i; each has modulus √13
- z = (6 ± √(36 − 52))/2 = (6 ± √−16)/2 = 3 ± 2i.
- |3 ± 2i| = √(9 + 4) = √13.

How to get ready
Students who do well at HL usually practise a little every week, redo the questions they got wrong, and ask for help as soon as a topic stops making sense, rather than at the mocks.

Common questions
Is AA HL harder than AI HL?
They are hard in different ways. AA HL leans on algebra, proof and calculus done by hand; AI HL leans on modelling, statistics and using technology well. Our AA or AI guide compares them.
What maths do I need before starting AA HL?
Schools set their own entry requirements, so ask yours. The skill that matters most is algebra: rearranging, factorising, fractions and indices without a calculator. Try the free AA HL baseline test to see where you stand.
Can I move from HL to SL later?
Many schools allow it, but each school sets its own rules and deadline. Talk to your teacher or DP coordinator early: it is much easier to move down than up.
Is the course changing?
Yes. The IB's revised AA and AI courses are first taught in August 2027, with the first exams in May 2029. See what changes.
