Maths Paper 1 and 2 Layout and Question Breakdown for Leaving Cert Higher Level

Maths isn’t a paper you can meaningfully try to predict*, so we offer you a summary of what has been on in the last number of years. It’s good to familiarise yourself with the layout and possible questions if Maths is a subject you struggle with. You may also like: Higher Level Maths for Dummies (€).

Proofs – the only predictable part

*The proofs section is the only one that appears to lend itself to recognising some patterns we can use. To that effect, we include the historic table below and make a cautious prediction as follows:
