IB Math AA HL vs SL: Syllabus, Papers and Formula Booklet Explained

IB Math AA HL vs SL: Syllabus, Papers and Formula Booklet Explained

IB Math AA HL and SL share the same five topic areas — number and algebra, functions, geometry and trigonometry, statistics and probability, and calculus — but HL adds extension content in each, runs to 240 teaching hours against SL’s 150, and sits three exam papers instead of two.

Key takeaways

• Both HL and SL study the same five syllabus components; HL simply goes deeper into each and adds dedicated HL-only content, including a distinct HL algebra topic.

• HL is 240 recommended teaching hours; SL is 150.

• SL sits two papers (Paper 1 and Paper 2); HL sits three, with Paper 3 as an HL-exclusive problem-solving paper.

• The internally assessed Exploration is worth 20% for both HL and SL, despite the different total teaching hours.

• Both levels are given an official formula booklet in the exam room — you don’t need to memorise every formula, but you do need to know how to use it under time pressure.

What Topics Are Covered in IB Math AA HL and SL?

Both courses cover the same five components — number and algebra; functions; geometry and trigonometry; statistics and probability; and calculus. Where they differ is depth: HL includes a dedicated “Algebra (HL)” extension section, more advanced complex numbers and vectors content, and significantly more calculus, on top of everything covered at SL. If you’re deciding whether AA is even the right math course for you in the first place, rather than which level within it, our existing IB Maths AA vs AI guide covers that decision — this page assumes AA is already your choice.

How Are IB Math AA HL and SL Assessed Differently?

Level

Recommended teaching hours

Typical number of subjects

Higher Level (HL)

240 hours

3 (sometimes 4)

Standard Level (SL)

150 hours

3 (sometimes 2)

 

SL students sit two papers, each worth 40% of the final grade, plus the internally assessed Exploration at 20%. HL students sit an additional Paper 3 — two compulsory extended-response, problem-solving questions — which shifts Papers 1 and 2 down to 30% each while Paper 3 picks up the remaining 20%.

What Is the IB Math AA Exploration (Internal Assessment)?

The Exploration is a piece of independent mathematical writing where you investigate a topic of your own choosing, worth 20 marks and 20% of your final grade at both HL and SL. It’s your one chance in this course to explore an area of maths that actually interests you — sports statistics, cryptography, architecture — rather than working entirely within set exam questions, and it’s assessed on criteria including mathematical communication, personal engagement and use of mathematics, not just correct answers.

Do You Get a Formula Booklet in the IB Math AA Exam?

Yes — both HL and SL students are given an official IB formula booklet in every paper. This doesn’t remove the need to know your formulas cold: the booklet lists them without context, so under time pressure, not immediately recognising which listed formula applies to the question in front of you costs far more time than memorising the common ones would have saved.

Common Mistakes in IB Math AA HL and SL

The most common mistake at HL specifically is underestimating Paper 3 — because it only carries two questions, students sometimes assume it’s “lighter” than Papers 1 and 2, when in practice its extended, multi-part problem-solving format rewards exactly the kind of practice that feels slowest to build. At SL, the most frequent issue is leaving the Exploration until close to the deadline, which limits how much genuine mathematical exploration (rather than confirmation of an answer you already suspected) actually makes it into the final write-up. Reviewing worked past papers by topic, rather than only doing full timed papers, is one of the fastest ways to close specific gaps — our IB Past Papers by Subject guide shows you where to find them for Math AA specifically.

Frequently Asked Questions

How many papers does IB Math AA HL have? Three — Papers 1 and 2, plus an HL-exclusive Paper 3 of extended problem-solving questions.

How many papers does IB Math AA SL have? Two — Paper 1 (no technology) and Paper 2 (technology allowed).

Is a formula booklet provided in the IB Math AA exam? Yes, both HL and SL students receive an official IB formula booklet in every paper.

How much is the IB Math AA Exploration worth? 20% of the final grade at both HL and SL.

How many teaching hours does IB Math AA HL require? 240 recommended hours, against 150 for SL.

Is IB Math AA harder than Math AI? They’re different in focus rather than strictly harder or easier — AA is more abstract and proof-based, AI is more applied and technology-driven; our AA vs AI guide covers how to choose.

What topics are HL-only in IB Math AA? A dedicated HL algebra extension, additional complex numbers and vector content, and extended calculus beyond the SL core.
