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 B150 marks on each paper
In 2025Four questions, answer any three
Typical partsRead, calculate, interpret, then extend
Our practiceEvery 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 first parts are building towards.

Write each step so it can be followed

Show the formula, the values you put in and the result, with units. If an early answer is wrong, clear working lets later parts still earn credit for a correct method.

Practise whole questions, not just topics

Section B joins topics: a savings account uses compound interest, a garden uses area and volume, a survey uses averages and the margin of error. Our paper-style questions are built the same way, one step per part.

Try 3 questions

Question 1Paper 1
Ciara puts 5,000 euro in a savings account that pays 3% compound interest per year. She adds nothing and takes nothing out. What is the account worth after 3 years, correct to the nearest cent?
Question 2Paper 1
The function  has a local minimum. What is the minimum value of f(x)f(x)?
Question 3Paper 2
A cylinder has radius 3.5 cm and height 10 cm. Find its volume, in cm3^3, correct to one decimal place.

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.
