What comes up in Leaving Cert Higher Level Maths

We read every question of every Higher Level Maths paper from 2017 to 2026 and noted the topics each one needs. Here is the full list, paper by paper and question by question, so you can see exactly where each topic has come up, and so teachers can check the counts printed in our Exam Ready workbooks.

How we count. A topic counts for a question when at least one of its parts can't be answered without it. One question often needs two or three topics.
Every question printed. We count all the questions on the paper, including the ones students could choose to skip.
The years. There were no written exams in 2020: grades were calculated instead. The 2021 and 2022 papers had extra choice because of the pandemic.
A guide, not a prediction. The papers are set fresh each year. Use this to plan revision, not to skip topics.
