✨Here are some top tips to make your revision more effective:

 1. Understand, Don’t Just Memorise🌟

Astronomy isn’t about memorising facts - it’s about truly understanding the reasons behind what happens in the universe.

Draw diagrams, label them and explain concepts in your own words. The better you understand them, the easier it’ll be to recall them in the exam.

2. Make a Revision Plan🗓️ 

There’s a lot to cover! Break down your topics into weekly chunks and focus on both naked-eye and telescopic astronomy.
Use a mix of resources: revision guides, flashcards and practice papers.

 3. Get Practical🔭

Go outside! 
Even a few minutes of stargazing helps you connect your learning to the real world. Try spotting constellations, phases of the Moon or the movement of planets - it makes your revision come alive.

 4. Practise Calculations🧮

There are always a few maths-based questions - like using the inverse square law, orbital calculations or angular size.
Practise these regularly so you don’t panic when they appear in the exam.

 5. Use Past Papers 📑

Past papers are your best friend! They help you get familiar with the question style and mark scheme.
Use the links on this page to past papers and mark schemes - time yourself to build confidence under exam conditions.

 6. Don’t Forget to Rest🧘

Your brain needs breaks to process information. Make time for rest, exercise and sleep  - you’ll retain more and feel calmer on exam day.
