The summer might have flown by, but now it’s time to hit the ground running. Sixth year is a big one, and if you’re taking Biology, you already know it’s a content-heavy subject with a lot to cover.
But here’s the good news, if you start with the right habits now, you can make the year far less stressful and far more successful.
1. Get Your Notes and Resources Organised Now
Biology is all about quality notes and good structure. By the end of the year, you’ll need:
A full set of concise, syllabus-focused notes (ideally in bullet points, not big blocks of text).
A practical experiment section for Section B, with clear diagrams and results.
Past exam questions grouped by topic for regular practice.
If your notes from 5th year are a bit patchy, fix them in the first 2-3 weeks of this school year otherwise, gaps now will cause headaches later.
2. Set a Weekly Biology Routine
Biology isn’t something you can cram for. The key is small, consistent chunks. Try:
1–2 hours per week revising past topics from 5th year.
1–2 hours on new material from class that week.
20–30 minutes of exam question practice each week, ideally on the topic you’ve just studied.
By Christmas, you should have gone through the entire 5th year course revised at least once.
3. Focus on Exam Technique Early
Leaving Cert Biology isn’t just about knowing the facts, it’s about answering in the style the Examiner expects.
That means:
Using marking scheme language in short, precise bullet points.
Always including keywords from the syllabus.
Knowing the layout:
Section A = short questions
Section B = experiments
Section C = long questions.
Start looking at past papers now. Even if you haven’t learned the full topic yet, reading model answers will train your brain to think like an examiner.
4. Stay On Top of the Practical Experiments
Section B is often underestimated but it’s 15% of your grade that you can prepare for perfectly.
Keep an experiment copy or folder with diagrams, methods, safety precautions, and sources of error.
After each practical in class, write it up the same day. Don’t let them pile up.
5. Use Your Teacher’s Experience
One of your best resources is your teacher.
Ask them:
Which topics are commonly tested and which tend to be paired together.
How to phrase definitions word-perfect for full marks.
Which experiments or topics are commonly mis-answered and what tricks to what out for.
6. Don’t Ignore the “Easy” Topics
Some chapters feel simple e.g. Characteristics of Life, The Scientific Method, Food, but these are often heavily tested in Section A.
Get them 100% learned early so you have guaranteed marks in the bag.
Remember Unit 1 (4 chapters) is 25% minimum of your grade!!
7. Keep Perspective
Sixth year can feel overwhelming, but remember:
Biology is a marathon, not a sprint.
Every small bit of study you do now is future stress you’re removing.
You don’t have to be perfect, you just have to keep moving forward consistently.
Final tip: September is about setting systems in place. Get organised now, keep your notes and exam question practice consistent, and you’ll find that when the mocks roll around, you’re already ahead of the game, not frantically trying to catch up.
