Chemistry | Grinds & Courses
Chemistry rewards students who understand the reasoning behind reactions and calculations, not just the formulae, and the practical experiments section is often the most under-revised part of the course. Our expert teachers combine exam-focused theory teaching with genuine attention to the practicals.

Weekly Grinds — Chemistry
29-week course, September 2026 – May 2027. Classes are 75 minutes. Chemistry is only taught as a distinct subject from 5th Year onwards; Junior Cycle years study combined Science instead.

What To Expect
Theory vs Experiments
Leaving Cert Chemistry tests two quite different skills, applying theory to calculations and reactions, and understanding the mandatory practical experiments.
Theory & Calculations
The bulk of the exam covers atomic theory, bonding, stoichiometry, acids and bases, rates of reaction, equilibrium and organic chemistry, tested through calculation-based and written questions.
Strong performance here depends on genuinely understanding the reasoning behind each calculation, not just memorising formulae.
Mandatory Experiments
A separate section of the exam is dedicated to the mandatory practical experiments, titrations, volumetric analysis, procedure, apparatus and sources of error.
Because it feels different from theory revision, this section is the one students most often under-prepare for, despite it being entirely predictable in scope.
The experiments section is entirely predictable, and often under-revised. Every mandatory experiment on the course could appear, so working through titration and volumetric analysis questions properly is a highly efficient use of study time relative to the marks on offer.
What to focus on
- Genuine understanding of calculations, not just memorised formulae
- Working through every mandatory experiment, especially titrations
- Practising past exam questions rather than only re-reading notes
- Balancing equations and correct units, since marks are lost easily on both
At the Institute of Education, weekly Chemistry classes give dedicated attention to the mandatory experiments alongside theory teaching, not just a quick pass near the exam.

Frequently Asked Questions
What level of Chemistry do you teach?
We teach Higher Level Chemistry only, from 5th Year onwards. Chemistry only exists as a distinct Leaving Cert subject from Senior Cycle, Junior Cycle years study combined Science instead. We do not currently offer a dedicated Ordinary Level Chemistry grinds option.
Where can I attend Chemistry grinds?
Chemistry is currently available at our Leeson Street location and online. It isn’t currently offered at Killester, Swords, Westmanstown or Dalkey.
Can I attend some classes online and others in person?
Yes. You can mix and match online and onsite classes across different subjects. Once enrolled in a specific class, though, you can only attend that class, whether online or in person.
How much do Chemistry grinds cost?
Fees depend on year group and how many subjects you take. For one subject, prices range from €1,020 (5th Year) up to €1,195 (6th Year) for the full 29-week course. Taking multiple subjects reduces the average cost per subject.
What’s included with Chemistry grinds?
Every student gets live teaching, free class recordings available to rewatch until the end of the State Exams, and exam-focused notes covering theory and the mandatory experiments.
Are Chemistry classes recorded if I miss one?
Yes. Every class, online or onsite, is recorded and available to rewatch through Moodle, right up until the end of the State Exams.
Does the exam cover the practical experiments?
Yes. A dedicated section of the exam covers the mandatory practical experiments, including titrations and volumetric analysis, alongside the theory and calculation-based questions in the rest of the paper.
Can I change my subject or class time during the year?
Yes. We allow class changes up to Easter, subject to availability. Contact our office on 01 661 3511 to arrange a change.
