Section B long questions
Each Section B question is one situation broken into parts. Later parts use earlier answers, so a clear method in part (a) carries marks through the question.
| Section B | 150 marks on each paper |
|---|---|
| In 2025 | Four questions of 50 marks, answer any three |
| Typical parts | Model, calculate, interpret, then extend |
| Our practice | Every step's answer checked as you type it |
Read the whole situation first
Before part (a), read every part. The last part often tells you what the model in part (a) is for, and that tells you which quantity to name as the variable.
Write each step so it can be followed
Show the formula, the values you substituted and the result. If an early answer is wrong, clear working lets the later parts still earn credit for a correct method.
Practise whole questions, not just topics
Section B joins topics: a loan uses geometric series, a design problem uses differentiation, a survey uses the normal curve. Our paper-style questions are built the same way, one step per part.

Questions people ask
What if I can't do part (a)?
Read on. Later parts often give you a value or an expression to use, so you can still answer them.
Are Section B questions harder than Section A?
They are longer and less direct, because you have to decide how the maths applies to the situation. Each part on its own uses the same skills as Section A.
