Maths and Computer Science learning resources

Explore original Maths and Computer Science worked examples, practice questions with solutions and IB Maths course-selection advice.

Your next step in learning

Choose a guide. Build understanding.

Choose a course guide, practise a mathematical method or trace an algorithm, one step at a time.

Worked example

Computer Science · Algorithms

Trace an algorithm step by step

Follow variable changes through a loop, check the output and practise a second algorithm independently.

Work through the table and practise
Worked example

IB Maths AA HL · Calculus

Make integration by parts clearer

Choose which factor to differentiate, keep track of signs and check your integral by differentiation.

Learn the method and check your answer
Decision guide

Course selection

Find your IB Maths pathway

Compare the approaches, separate route from level, and use a practical checklist before committing to a course.

Compare AA, AI, SL & HL
Worked example

Proof and reasoning

Make induction make sense

Turn a pattern into a proof with a fully explained example, a common-error checklist and a practice question with a solution.

Follow the proof and try a question

Learn actively

From reading a solution
to explaining it yourself.

A worked example is a starting point. Use these three steps to turn it into something you can do independently.

  1. Try before you read

    Attempt the question first. Write down where you get stuck.

  2. Find the first difference

    Compare your reasoning with the solution, one step at a time.

  3. Close it. Explain it. Retry.

    Work through the question again without looking at the answer.
