Leaving Cert Chemistry Exam Review: Familiar Topics, Fresh Challenges (2026)

The Familiar Yet Unpredictable World of Chemistry Exams: A Reflection on This Year’s Leaving Cert

There’s something almost poetic about how chemistry exams manage to balance the familiar with the unexpected. This year’s Leaving Cert chemistry paper was no exception. On the surface, it seemed like a nod to tradition—teachers praised its ‘familiar topics’ and ‘good range of choice.’ But dig a little deeper, and you’ll find a paper that subtly challenged students to think beyond rote memorization. Personally, I think this is where the real beauty of the exam lies: it’s not just about what you know, but how you apply it.

The Comfort of Familiarity—But at What Cost?

Mary Mullaghy, a chemistry teacher at Eureka Secondary School, noted that the paper rewarded students who ‘engaged fully with the syllabus.’ What makes this particularly fascinating is how it reflects a broader trend in education: the tension between preparing students for predictable questions and equipping them to handle surprises. The inclusion of ‘traditional old chestnuts’ might feel reassuring, but it also raises a deeper question: Are we inadvertently discouraging critical thinking by over-relying on past patterns?

From my perspective, the integration of topics in question two was a masterstroke. It wasn’t overly complex, but it required students to connect dots they might not have anticipated. This is where the exam shifted from being merely ‘fair’ to ‘testing.’ John O’Sullivan, head of chemistry at the Tuition Centre, aptly described it as a paper with ‘a few fresh angles.’ What this really suggests is that even in a subject as structured as chemistry, there’s room for creativity—both in teaching and in assessment.

The Art of Distinguishing the Top Scorers

One thing that immediately stands out is Tara Lyons’ observation about question three. The topic of ions in water was familiar, but the inclusion of a calculation was a curveball. What many people don’t realize is that this kind of question isn’t just about testing knowledge; it’s about testing adaptability. In a world where information is readily accessible, the ability to apply knowledge in novel ways is what truly sets students apart.

The free-radical question in question five is another example of this. It was a familiar topic, but asked in a way that hadn’t been seen before. If you take a step back and think about it, this is a brilliant strategy by the State Examinations Commission (SEC). They’re not just assessing recall; they’re assessing understanding. And that, in my opinion, is the hallmark of a well-designed exam.

The Ordinary Level: A Fair Shot or a Missed Opportunity?

Mullaghy’s take on the Ordinary Level paper was that it was ‘appropriately pitched.’ While I agree that it provided broad coverage of the syllabus, I can’t help but wonder if it could have pushed students a little harder. The Ordinary Level often gets less attention in these discussions, but it’s just as crucial. After all, it’s the foundation upon which higher-level learning is built.

A detail that I find especially interesting is how the paper aimed to ‘demonstrate practical skills.’ Chemistry isn’t just about theory; it’s about application. Yet, so often, exams focus disproportionately on the former. This paper seemed to strike a better balance, which is encouraging.

The Broader Implications: What Does This Exam Tell Us About Education?

This year’s Leaving Cert chemistry paper isn’t just a snapshot of one exam; it’s a reflection of larger trends in education. The emphasis on familiarity versus novelty, the push for critical thinking, the attempt to bridge theory and practice—these are all part of a broader conversation about what we want education to achieve.

What this exam really highlights is the delicate dance between consistency and innovation. Students need a solid foundation, but they also need to be prepared for the unexpected. Personally, I think we’re moving in the right direction, but there’s still room for improvement. For instance, why not introduce more open-ended questions that encourage creativity? Or integrate real-world scenarios to make the subject more relatable?

Final Thoughts: A Fair Exam, But Is That Enough?

Overall, this year’s Leaving Cert chemistry paper was, as O’Sullivan put it, ‘fair but testing.’ Students who had prepared well likely felt confident, while those who relied too heavily on past papers might have been caught off guard. But here’s the thing: fairness is important, but it shouldn’t be the ultimate goal. Education should challenge, inspire, and prepare students for a world that’s anything but predictable.

As I reflect on this exam, I’m left with a provocative thought: What if we stopped seeing exams as endpoints and started viewing them as stepping stones? What if, instead of just testing knowledge, we used them to foster curiosity, resilience, and a love of learning? That, in my opinion, would be the ultimate measure of success.
