If you're looking for a detailed guide to help you prepare for IB Math AI Paper 1, you're in the right place! In this post, we’ll break down everything you need to know about the structure of Math AI Paper 1, so you are fully informed before you take the exam.
IB Math AI Paper 1
Paper 1 is made up of a mix of short-response and extended-response questions, all based on the entire syllabus.
The paper assesses a broad range of mathematical concepts, with a strong emphasis on real-world problem-solving and interpretation of data in various forms.
SL papers have a maximum of 80 marks, while HL papers have a maximum of 110 marks.
For SL, Paper 1 contributes 40% to the overall subject grade, while for HL, it contributes 30%.
SL students have 1 hour and 30 minutes, while HL students are given 2 hours to complete Paper 1.
Questions are presented using words, tables, graphs, or diagrams—often combining these to reflect real-world contexts.
Questions gradually increase in difficulty, starting with the easier problems and progressing to more complex ones.
Section A
Section A includes a range of short-response questions, targeting a broad scope of the syllabus.
Students may score up to 40 marks in this section.
Questions typically require a small number of clear steps to solve and test the student's fundamental understanding of the course material.
Problems are often presented in contexts involving numerical reasoning, algebra, statistics, or simple modeling.
A typical SL question could be:
A company sells notebooks for $x each. The profit, in dollars, is given by
P(x) = -5x² + 100x - 200.
(a) Find the number of notebooks that should be sold to maximize the profit. [3 marks]
(b) Find the maximum profit. [2 marks]
A typical HL question could be:
The quadratic function f(x) = ax² + bx + c has roots at x = 2 and x = 5.
Given that f(0) = -10,
(a) Find the values of a, b, and c. [4 marks]
(b) Hence, sketch the graph of f(x), labeling key points. [3 marks]
Section B
Section B consists of extended-response questions involving deeper reasoning and more complex problem-solving.
It is also worth up to 40 marks.
Questions in this section often require knowledge of multiple topics, requiring students to integrate skills learned from various areas of the syllabus.
Students are expected to write detailed step-by-step solutions, showing logical progression and justifying their reasoning.
A typical SL question could be:
A data set shows the number of hours students study per week and their exam scores.
(a) Calculate the mean and standard deviation of the data. [3 marks]
(b) Plot the data on a scatter diagram and determine the correlation. [3 marks]
(c) Find the equation of the regression line and use it to predict the score for a student who studies 15 hours. [3 marks]
A typical HL question could be:
A researcher models the growth of a bacterial population using the function
P(t) = P₀ekt, where P₀ is the initial population, and k is a constant.
(a) Given P(0) = 50 and P(4) = 200, find the value of k. [3 marks]
(b) Estimate when the population will reach 500. [3 marks]
(c) Comment on the limitations of this model. [2 marks]
How to Succeed in IB Math AI Paper 1
Strengthen real-world skills – Math AI emphasizes applications in real-life scenarios. Familiarize yourself with interpreting graphs, analyzing data, and providing solutions to real-world applications of math.
Show all working clearly – IB provides method marks even without a correct final answer. A clear step-by-step solution should be present to allow the examiner to see your thought process. Define variables, write down formulas, and explain reasoning as you work through each question.
Review core concepts thoroughly – Focus on core skills like percentages, ratios, functions, statistics, sequences, and probability. These often appear in real-world contexts and can hence be tested in the Math AI exam.
Solve numerous past papers – This helps you get used to the type of questions that could be asked on the exam and helps you develop skills in learning which mathematical concepts to apply. You should try to solve past papers using a timer to simulate exam conditions and check your answers against a markscheme to identify areas for improvement.
Master the GDC – Learn and practice the important functions on your GC so that you are familiar with them during the exam. The GDC is an important tool that is allowed even in Paper 1 (unlike Math AA where Paper 1 is non-calculator), so it is important to know how to use it effectively.
