Leaving Certificate Chemistry combines theory, calculations and practical experiments, which means students need to develop several different skills. Knowing the course is important, but avoiding common exam mistakes can also make a significant difference to your final grade.
1. Learning Without Understanding — Chemistry contains plenty of definitions, equations and rules, but simply memorising them isn't enough. Make sure you understand why reactions occur and how different concepts connect.
2. Not Showing Your Calculations — always show your working in calculation questions. Even if your final answer isn't correct, clearly showing your method may still help you earn marks.
3. Ignoring Units — always check that your final answer contains the correct units where required.
4. Neglecting Experiments — practical experiments are an important part of the course, so know the apparatus, procedures, observations, calculations and safety precautions for each required experiment.
5. Not Balancing Chemical Equations — take the extra time to check your equations, since small errors can affect the rest of a calculation or explanation.
6. Avoiding Difficult Calculations — topics involving calculations often become much easier with practice. Don't simply read worked examples — attempt the questions yourself before checking the solution.
7. Not Using Past Papers — past exam papers help you understand how Chemistry concepts are actually examined, so complete questions regularly and use the marking schemes to see where marks are awarded.
