What's involved?

Assessment for Leaving Cert Computer Science can be broken down into two parts: the coursework project and the written exam (contains a programming component). Here's a breakdown:

Coursework project

This is worth 30% of your overall grade and is completed over a 10-week period between January and March of 6th year.

Written exam

This exam is split into two components mark-wise. The written part is worth 130 marks (43%) and the programming part is worth 80 marks (27%). Here's a breakdown of the exam:

  • Section A is made up of 12 short questions.
  • Section B is made up of 3 long questions.
  • Section C is the programming component of the exam

The programming component will consist of one question (which may be split into multiple parts) which may be rooted in any of the three main languages (Python, JavaScript or HTML). However, since 2021, Python is the only language to have been examined.

This is worth 30% of your overall grade and is completed over a 10-week period between January and March of 6th year.

How to study computer science

Practice past exam questions

One of the most effective ways to study computer science is to practice past exam paper questions. The more questions you can do, the fewer surprises you'll have on the day of your exam. 

This is why we have broken down all of the past exam paper questions into neat topics. This will save you loads of time searching for the right questions. You can find a list of question topics on the computer science page.
