How Many IB Maths AI Papers Are There?

If you're studying IB Maths Applications and Interpretation (AI), you're probably wondering how many exam papers you'll need to sit. 

You'll sit either 2 or 3 papers, depending on whether you're taking Standard Level (SL) or Higher Level (HL). But there's more to it than just the numbers.

Let's take a look at everything you need to know about the IB Maths AI exam structure in our comprehensive guide below.

Key Takeaways

• SL students sit 2 papers (Paper 1 and Paper 2) plus complete an Internal Assessment.

• HL students sit 3 papers (Paper 1, Paper 2, and Paper 3) plus complete an Internal Assessment.

• All papers allow calculators. This is a key feature of the AI course.

• Each paper tests different skills but all focus on real-world applications and mathematical modelling.

IB Maths AI Exam Structure Overview

IB Maths AI is all about applying mathematics to real-world situations. Unlike its sister course (Analysis and Approaches or AA), AI focuses on modelling, data interpretation, and practical problem-solving. Here’s the exam structure at a glance:

Standard Level (SL):

• 2 papers (Paper 1, Paper 2)

• SL students have two exam papers worth 80% of their final grade. 

Higher Level (HL): 

• 3 papers (Paper 1, Paper 2, Paper 3) 

• HL students have three exam papers, combined to be worth 80% of their final grade.

Both levels: 

• Every student also completes an Internal Assessment (IA) worth 20% of their final grade. This is a mathematical exploration you'll work on throughout the course.

The beauty of the AI course is that calculators are allowed in all papers. In fact, they're not just allowed. They’re needed. You'll be expected to use your graphical display calculator (GDC) skilfully throughout. 

Paper 1: Short-Response (Calculator Allowed)

Paper 1 is taken by both SL and HL students, though the content difficulty varies between levels.

This paper focuses on short-response questions that test you on what you’ve learned throughout your two-year course. You'll be working with real-world data and solving practical problems.

The questions often involve:

• Statistical analysis

• Data interpretation

• Functions and their applications

• Probability scenarios

• Geometric problem-solving (including trigonometry)

Revision tips for Paper 1:

• Practice identifying which mathematical methods to use for different problem types.

• Get comfortable with your GDC - know its functions inside and out.

• Work through plenty of data-handling questions.

• Time yourself regularly to build exam confidence.

Paper 2: Extended-Response (Calculator Allowed)

Paper 2 steps things up a notch. Both SL and HL students sit this paper, but again, the complexity differs.

This paper focuses on extended problem-solving, with much more mathematical reasoning thrown in. Questions typically require multiple steps and deeper analysis than Paper 1.

You'll encounter:

• Complex modelling scenarios.

• Multi-part problems that require sustained thinking.

• Questions that test your ability to communicate mathematical reasoning.

• Real-world contexts that need careful interpretation.

Revision tips for Paper 2:

• Focus on clear communication. Examiners need to follow your thinking.

• Practice showing all your working, even when using a calculator.

• Develop strategies for breaking down complex, unfamiliar problems.

• Work on explaining your mathematical reasoning in words.

Paper 3: HL Only – Extended-Response Problem-Solving

If you're taking HL, Paper 3 is your additional challenge. Paper 3 consists of extended response questions that really test your mathematical maturity.

This paper contains just two questions, but they're substantial. Each question presents a real-world scenario that requires deep mathematical analysis and modelling.

You'll need to:

• Apply multiple mathematical concepts to complex situations.

• Demonstrate sophisticated use of your GDC.

• Communicate your mathematical thinking clearly and logically.

• Show genuine mathematical reasoning and problem-solving skills.

Revision tips for Paper 3:

• Use past Paper 3 questions to practice tackling unfamiliar contexts.

• Focus on breaking down complex problems into manageable chunks.

• Develop your mathematical communication skills.

• Practice using technology to explore and solve extended problems.

Exam Paper Weightings for SL and HL

Here's how your exam papers contribute to your final IB Maths AI grade:

These weightings will influence your revision strategy:

For SL students: Papers 1 and 2 carry equal weight, so you should spend roughly equal time preparing for each. Practice short-response and extended-response questions as part of your revision.

For HL students: Papers 1 and 2 are worth less individually, but they still make up 60% of your grade combined. Paper 3, though worth 'only' 20%, can significantly impact your final result.

What Is the Internal Assessment (IA) for IB Maths AI?

Your IA is a mathematical exploration based on a topic that genuinely interests you. It's your chance to dive deep into an area of mathematics that connects to your passions or future career plans.

The IA should demonstrate:

• Personal engagement with mathematics

• Mathematical reasoning and problem-solving

• Clear communication of your findings

• Appropriate use of technology

Strong IA topics for AI students include:

• Analysing sports statistics to predict performance

• Modelling population growth or decline

• Investigating financial mathematics (loans, investments, etc.)

• Exploring mathematical patterns in music or art

• Analysing environmental data and trends

If you’re in need of more IA inspiration, the International Baccalaureate Organisation has compiled a repository of projects (opens in a new tab) to help you narrow down your topic.

Tips:

• Start early. Don't leave it to the last minute.

• Choose a topic you're genuinely curious about.

• Use real-world data whenever possible.

• Show deep mathematical thinking, not just calculations.

• Think about how you’ll communicate your mathematical findings in words.

• Get regular feedback from your teacher.

Frequently Asked Questions

How many papers are there in IB Maths AI SL?

There are two exam papers for SL students – Paper 1 and Paper 2. You'll also complete an Internal Assessment or ‘exploration’ during the course.

How many papers are there in IB Maths AI HL?

HL students sit three papers – Paper 1, Paper 2, and Paper 3. Like SL students, you'll also complete an Internal Assessment.

Is the IA the same for SL and HL?

Yes. The IA requirements are identical for both SL and HL students. It's worth 20% of your final grade, regardless of level.

Which paper is the hardest?

This depends. IB Maths is a challenging course. You can find out just how challenging it is by taking a look at our ‘Is Maths IB Hard?’ overview. 

In terms of the assessments, many find Paper 2 challenging due to its extended problem-solving format. These sorts of questions require more sustained mathematical reasoning than short-response questions. 

HL students often find Paper 3 demanding because it requires even more sophisticated mathematical reasoning. However, with proper preparation, all papers are absolutely manageable.

Final Thoughts

Knowing how many IB Maths AI papers there are is key to boosting your confidence and helping you feel prepared. With either 2 or 3 papers to sit (depending on your level), you've got a clear target to aim for.

Remember, every paper allows calculator use. This is designed to help you focus on mathematical thinking rather than tedious calculations. Make sure you're comfortable with your GDC and know how to use it efficiently.

And, don’t forget that your IA is worth a significant chunk of your final grade. Start early, choose something you're passionate about, and use it as an opportunity to showcase your mathematical curiosity.

Most importantly, maximise your preparation for the exams. Head over to the Learning Hub and get familiar with the AI question formats using the past papers at Save My Exams. The more you practice, the more confident you'll feel come exam day.
