IBDP Maths – MAA and MAI Resources- Syllabus, Practice Questions and Notes

## IBDP Maths MAA and MAI

Maths in IBDP is required at either standard level or higher level. You can take two courses: Analysis & Approaches (AA) or Applications & Interpretations (AI). Each course covers the same 5 topics (Number & Algebra, Functions, Geometry & Trig, Statistics, and Calculus), with different focus and weightage. Higher level courses in both AI and AA cover content in-depth, and also harder topics.

Whereas Math AI focuses more on the practical applications of math, with emphasis on functions and statistics, Math AA is a more traditional course, with more emphasis on number & algebra, geometry & trig, and calculus. As for the actual content, you can refer to the subject guides for each course.

#### What is Maths AA and AI?

Maths AA and AI are the two new IB mathematics courses introduced which replaced the old IB mathematics curricula for first assessment in May 2021. Maths AA stands for Mathematics: Analysis and Approaches and Maths AI stands for Mathematics: Applications and Interpretations. If you are an IB Diploma, it is compulsory to take one of these two courses at either Standard Level or Higher Level.

#### What are the differences between Maths AA and Maths AI?

Oh, this is the big one, so I’ll cut to the chase. The most prominent differences are found in the teaching hours for each of the courses’ components, in this next table. If you can’t understand it, don’t worry, as I’ve explained it after the table.

COMPONENT NAMEAA SLAI SLAA HLAI HL
Number and Algebra19163929
Functions21313242
Geometry and Trigonometry25185146
Statistics and Probability27393352
Calculus28195541

The table shows that there are significant differences between the two courses in terms of content weightage. In essence:

• Maths AA gives more emphasis on Number & Algebra, Geometry & Trigonometry and Calculus.

• Maths AI gives more emphasis on Functions and Statistics & Probability.

The subject brief also describes the nature of the two courses’ syllabi:

• Maths AA:

• Develops important mathematical concepts in a rigorous way

• Solves abstract problems as well as ones set in a meaningful context

• Emphasizes on construction, communication and justification of correct mathematical arguments

• Teaches students to have insights into mathematical form and structure

• Maths AI:

• Emphasises on mathematics used in applications or mathematical modelling

• Includes traditional components such as calculus and statistics

• Develops strong technology skills

• Encourages students to solve real world problems, construct and communicate them mathematically and interpret conclusions or generalisations

There is also a difference in their assessments.

Maths AA has one paper which prohibits the use of a calculator, Paper 1. Paper 2 and HL Paper 3 permit calculator use. Maths AI permits calculator use in all papers.

Maths AA paper 1 and paper 2 each are divided into two sections. Section A has short response questions, and Section B has extended-response questions. Maths AI paper 1 is exclusively short response questions, and paper 2 is exclusively extended response questions.

Note that HL paper 3 for both AI and AA are extended-response problem solving questions, and both of them share the same format, but have differing questions due to their differing syllabi.

Maths AA is the ‘analytical’ based, heavy on calculus and geometry/trigonometry. You cannot use a calculator in one paper. Maths AI is more ‘application’ based, heavy on functions and probability/statistics. You must use a calculator in all papers.

Which one is more useful in university?

Also one of the most common questions. Unfortunately, it is a very vague one. Neither is inherently ‘more’ useful, as it is entirely dependent on the region and your ambition in college or university.

If there is a preference for AA or AI in terms of courses, it exists for engineering or mathematics-heavy courses such as Physics or Math degrees. In these cases, AA is preferred or even required, but it only applies to countries that even differentiate between AA or AI.

I have made a very brief summary for certain popular countries for further studies and their trends for preferring AA or AI. But there exists so many exceptions that it is unjustifiable to even call it a ‘trend’ so please take this with a grain of salt and rely more on your own research.

• United States: No AA/AI differentiation, but may require/prefer HL over SL for math heavy degrees

• Canada: No AA/AI differentiation, but may require/prefer HL over SL for math heavy degrees

• Australia: No AA/AI differentiation

• United Kingdom: There are cases of differentiation in a considerable number of universities. Generally, AA HL is the course which opens the most doors, as nearly all engineering and math heavy degrees require AA HL. Many competitive economics programs even prefer or require AA HL. Of course, there are major exceptions, most notably being Oxbridge which has no preference between the two, as they already have their own entrance exams which include maths. Unfortunately, I have personally never seen any case where AI is preferred over AA, but the other way round is very common. Do correct me in the comments if you come by any exception.

So, which course should I select?

Honestly, this depends on a variety of factors. Most notably, your performance and attitude in studying mathematics, and your individual strengths or weaknesses in individual components that may lead you to choose one course or another. If you are one of those all-rounders in mathematics, then perhaps you could choose based on university plans. If you are not confident in mathematics skills but still want to pursue math-related degrees, it is also an important factor to consider.Overall, remember that you are going to spend 2 years with this subject, so make sure you like what you’re doing, and have confidence in doing well in the subject in your IB exams. Do remember to consult your teachers, school, friends and family for advice on subject selection.

So that pretty much is the end. I may have missed out certain points, maybe even have some inaccuracies, but it is the least I could do for future IB students. I hope you found this useful, and do feel free to comment with your own perspectives!

Two new courses  became part of the Diploma Programme (DP) in 2019, both taught at the Higher level (HL) and Standard level (SL). The first is Mathematics: analysis and approaches and the second is Mathematics: applications and interpretation.

From August 2019 the following courses, with first assessment in May 2021, are available:

• Mathematics: analysis and approaches SL
• Mathematics: analysis and approaches HL
• Mathematics: applications and interpretation SL
• Mathematics: applications and interpretation HL

Students can only study one course in mathematics as part of their diploma.

Each course approaches topics at varying levels of teaching hours. This guide will provide some insights into which course will be the best fit for your school and students.

The courses are separated by how they approach mathematics, described generally by the table below:

#### Mathematics: analysis and approaches

• Emphasis on algebraic methods
• Develop strong skills in mathematical thinking
• Real and abstract mathematical problem solving
• For students interested in mathematics, engineering physical sciences, and some economics

#### Mathematics: applications and interpretation

• Emphasis on modelling and statistics
• Develops strong skills in applying mathematics to the real-world
• Real mathematical problem solving using technology
• For students interested in social sciences, natural sciences, medicine, statistics, business, engineering, some economics, psychology and design

All of these courses (SL and HL in each) cover the same 5 topics within mathematics but with varying emphasis in each area: number and algebra, functions, geometry and trigonometry, statics and probability, and calculus. The chart below may help you select the right course based on the amount of time dedicated to a given topic.
