IB Maths AI Paper 2: The Complete Guide for SL and HL
IB Maths Applications and Interpretation (AI) is one of two IB Maths courses available to students, with the other being Analysis and Approaches (AA). Maths is a mandatory subject at IB-level and, with the Maths AI going through an update for first assessment in 2029, it is vital that students are clear on what is expected of them when they take their seats in the exam hall.
The number of papers to be sat by IB Maths AI students differs depending on whether the individual is taking Standard Level (SL) or Higher Level (HL) Maths AI. For SL learners, they must complete two exam papers; for HL learners, they must complete three. The focus of today’s post is on the Paper 2 component, which both SL and HL students sit, with attention paid to current and updated syllabus.
What Is IB Maths AI Paper 2?
The IB Maths AI Paper 2 is a compulsory paper for both SL and HL learners. The paper consists of extended-response questions for which a calculator can be used. In fact, the employment of a graphic display calculator (GDC) is one of the defining features of Maths AI. Unlike Maths AA, technology can be used in each of the examination papers for Maths AI.
To understand the differences between Paper 2 at SL and HL, take a look at the following table:
SL |
HL | |
|---|---|---|
Time allowed |
1 hour 30 minutes |
2 hours |
Total marks |
80 marks | 110 marks |
Weighting |
40% | 30% |
Paper Format |
Extended-response, GDC required | Extended-response, GDC required |
Sections |
None | None |
Additional Papers |
None | Paper 3, 1 hour, 55 marks, 20% |
HL-only topics that can appear |
- | Matrices, vectors, graph theory, differential equations, complex numbers |
Be aware that this information is related to the current syllabus. Therefore, it is for students sitting their exams in 2027 and 2028. For those taking the updated course in the 2029 examination cycles, there are some differences. For example, the SL paper will be marked out of 75 rather than the current 80 marks. Similarly, the HL paper will be marked out of 100 instead of 110.
What Topics Can Come Up in IB Maths AI Paper 2?
What distinguishes Maths AI from AA is the applied, real-world framing of every question. The idea behind the paper is to illustrate to students how mathematics can feature in daily life. Consequently, questions can span topics and are not clearly delineated. This means that students must be confident in their subject knowledge across all course topics.
For clarity, the table below illustrates the Maths AI topics and the recommended teaching hours.
Topic |
SL Hours |
HL Hours |
|---|---|---|
Number and algebra |
16 |
29 |
Functions |
31 | 41 |
Geometry and trigonometry |
18 | 46 |
Statistics and probability |
36 | 52 |
Calculus |
19 | 41 |
It is plain to see that statistics and probability is the largest content topic at both Standard and Higher Level and, historically, carries the most marks in Paper 2. Moreover, the difference in teaching hours between SL and HL suggests the relative importance of certain topics within the course. For example, functions is the second-largest topic at SL, while geometry and trigonometry is the second-largest at HL.
Not included here is, of course, the HL-only content. These topics are:
Matrices
Vectors
Graph theory
Differential equations
Complex numbers
For the assessment in 2029, the Maths AI topics have been reorganised into five lettered sections. These are:
- Topic A: Functions
- Topic B: Number and algebra
- Topic C: Geometry
- Topic D: Probability and statistics
- Topic E: Calculus
Students should also note that teaching hours for HL students studying functions will increase from 42 to 45, while teaching hours for geometry among these same learners will decrease from 46 to 45.
For this syllabus update, no content has been added. Rather, it has been reduced. For instance, at SL, logarithms and the trapezoidal rule have been removed; at HL, complex numbers, the vector product, the Poisson distribution and three hypothesis tests no longer feature.
IB Maths AI Paper 2 Exam Techniques
To excel in the IB Maths AI Paper 2 exam, candidates should refine a number of skills.
As the questions on the AI Paper 2 examination are extended response questions, it is important to read over each in full before attempting an answer. Next, approach each part in isolation. Do not try to answer everything all at once but go step-by-step. It should also be noted that, as earlier answers feed later parts, a wrong carry-forward used correctly will still earn method marks.
It is also important to interpret all results within the real-world context of the questions. This is a signature skill within IB Maths AI and a distinct assessment objective. After every calculation, IB Maths candidates should make sure that their answers make sense in context. A correct numerical answer without contextual interpretation may result in marks lost.
One skill often overlooked is GDC (graphic display calculator) fluency. As noted, calculator use is fundamental to all AI papers. Consequently, students should be able to utilise the technology with ease. Maths AI’s applied character means the statistical and financial functions of the GDC matter most—regression (including non-linear), distributions, chi-squared and other hypothesis tests, confidence intervals, and the finance/TVM solver. It is recommended that learners drill these topics to ensure that they are not encountered for the first time mid-exam paper. Additionally, students should be sure to show their workings. While calculators are an excellent tool, marks can be lost if a student’s methodology is not documented and nothing more than the final answer is given.
Another crucial skill is the ability to successfully navigate the formula booklet. All Maths AI students receive a formula booklet for use in their exams. However, this booklet is not something held in secret and students should familiarise themselves with it ahead of their exams. By doing so, time and, most likely, marks will be saved.
Ultimately, exam technique can only be correctly utilised if carefully honed through revision and practice. This often starts with a well-organised revision plan.
How to Build an IB Maths AI Paper 2 Revision Plan
The most effective revision tool is past exam papers. However, they are only effective if they are utilised correctly. It is no use diving right into past paper questions without first looking over a few carefully to gain an understanding of how the exam is formatted and the information laid out. So, review past papers, examine the instructions given, and establish how many questions feature on a Paper 2 and the language used.
Next, complete a full paper under timed conditions. The benefit of working through a full exam paper under timed conditions is that it allows students to see not only where they excel but topics in which they struggle. Constructing a competent revision plan is about isolation areas and strength and weakness and exam papers are the most effective way of getting started. Moreover, completing practice papers under exam conditions allows students to get a sense of their time management skills.
Mark schemes are an essential tool of all good revision sessions when a past paper is involved. By closely examining the associated mark schemes, IB Maths AI candidates understand why marks were awarded, not just whether the answer was right or wrong. In a sense, the exam is somewhat demystified and signals to IB learners how they can better maximise their scoring.
As the use of a GDC is expected in IB Maths AI, some time during revision sessions should be given over to achieving mastery of this tool. Spend time learning how the machine works and how it can best be used in answering different question types across topics. While it may seem intuitive, it’s better to be prepared than caught out mid-exam.
For those sitting their Paper 2 in 2029, past papers from the current syllabus, whose first assessment took place in 2021, will not map directly onto the new course structure. However, that does not mean that the papers have no use at all. Students beginning their IB journey in August 2027 can use current papers for technique practice while making sure that any topic revision aligns to the new syllabus once official materials are available.
Achieving a high level of topic knowledge, comfort with both the GDC and formula booklet, and confidence in answering the types of questions found on the IB Maths AI Paper 2 takes time. It can be challenging to cover so much ground alone. For this reason, the guidance of an expert IB Maths tutor can make all the difference.
