How Many IGCSE Co-ordinated Sciences Papers Are There?

If you’re preparing for IGCSE Co-ordinated Sciences, one of the first things you’ll need to know is how many exam papers you actually need to sit. Between different tiers, practical papers, and separate Biology, Chemistry, and Physics content, the exam structure seems more complicated than it really is.

The important thing to remember is that you only need to focus on the papers for your own qualification and exam tier.

IGCSE Co-ordinated Sciences combines all three sciences into one course and usually awards two grades overall. Once you know how the assessment is organised, it becomes much easier to plan your revision and feel confident about what to expect in the exams.

This guide explains how many IGCSE Co-ordinated Sciences papers there are, how the exams are structured, and what to expect from the Cambridge qualifications.

Key Takeaways

• Cambridge IGCSE Co-ordinated Sciences qualifications use three assessment papers overall

• Students study Biology, Chemistry, and Physics together within a single course

• The qualification includes multiple-choice, theory, and practical assessment papers

• Practical skills are assessed either through a practical test or an Alternative to Practical paper

IGCSE Co-ordinated Sciences Assessment Structure Explained

IGCSE Co-ordinated Sciences qualifications are linear courses, which means you take all of your exams at the end of the course rather than completing modules throughout the year.

The course combines key topics from Biology, Chemistry, and Physics into one qualification. This means you will be revising content from all three sciences at the same time, so staying organised throughout the course is important.

Across the Cambridge specifications, students study topics such as:

• cells and human biology

• chemical reactions and bonding

• electricity and energy

• forces and motion

• ecology and the environment

• atomic structure and particles

This combination of subjects means you will need to switch regularly between different scientific ideas and skills, from calculations in Physics to practical methods in Biology and Chemistry.

Most assessments are completed through written examination papers. However, the qualification also includes practical assessment components through either a practical test or an Alternative to Practical paper.

There is no coursework or controlled assessment, so your final grades are based entirely on your exam performance.

How Many Exam Papers Are There For IGCSE Co-ordinated Sciences?

Both Cambridge IGCSE Co-ordinated Sciences qualifications use three assessment papers overall. Together, these papers assess scientific knowledge, calculations, practical understanding, and scientific reasoning skills across Biology, Chemistry, and Physics.

Students complete one multiple-choice paper, one theory paper and one practical assessment paper.

Depending on your centre, the practical assessment may be completed through either a practical test carried out in a laboratory or an Alternative to Practical written paper.

The exam papers include a mixture of:

• multiple-choice questions

• structured written questions

• calculations

• practical-skills questions

• extended scientific reasoning

Breakdown by Qualification

Cambridge IGCSE Co-ordinated Sciences (0654/0973)

Additional details:

• Students study Biology, Chemistry, and Physics together

• Core candidates take Paper 1 and Paper 3, with questions based on the Core subject content only

• Extended candidates take Paper 2 and Paper 4. Questions are based on Core and Supplement subject content

• Practical skills are assessed through either practical work or written practical questions

• Practical and investigative skills are assessed alongside scientific knowledge

Cambridge offers two versions of the qualification:

• Cambridge IGCSE Co-ordinated Sciences (0654) (opens in a new tab), which uses the A*–G grading system

• Cambridge IGCSE Co-ordinated Sciences (Double Award) (0973) (opens in a new tab), which uses the 9–1 grading system

Both qualifications award two grades overall and use the same assessment structure.

Tips for Preparing for IGCSE Co-ordinated Sciences Papers

Revise all three sciences regularly

IGCSE Co-ordinated Sciences includes content from Biology, Chemistry, and Physics, so it is important to keep revising all three subjects throughout the course.

It's tempting to focus only on the science you enjoy most, especially if one subject feels easier than the others. However, balanced revision helps stop weaker topics from becoming much more difficult later on.

You’ll find plenty of advice in our Learning Hub, including tips on when to start revising for IGCSEs and IGCSE revision advice and strategies, to help you get organised.

Practise scientific calculations carefully

Many students lose marks in science exams because of calculation mistakes rather than misunderstanding the science itself.

Make sure you practise:

• rearranging equations

• using units correctly

• showing clear working

• rounding answers appropriately

This is especially important in Physics and Chemistry questions, where small calculation errors can quickly cost marks.

Build confidence with practical skills

Even when practical work is assessed through written questions, you still need to understand:

• experimental methods

• variables

• graph skills

• scientific investigations

• analysing results

Many practical-skills questions test your ability to apply scientific knowledge in unfamiliar situations, so practising these skills regularly helps build confidence.

Use past papers regularly

Using past papers is a great way to identify weaker topics early, giving you more time to improve them before the final exams.

Past papers also help you become familiar with:

• question wording

• timing

• calculations

• practical-skills questions

• extended written answers

Practise under timed conditions

Preparing for Co-ordinated Sciences exams can feel overwhelming because you’re revising content from three sciences at the same time. 

Try to reduce the pressure by practising timed questions. Even tackling a few exam questions successfully against the clock can help you feel much calmer and more prepared for the real exams.

Timed practice helps improve your skills in:

• exam pacing

• confidence under pressure

• interpreting questions

• writing extended scientific answers

That’s why your teachers spring all those tests on you throughout the course!

Frequently Asked Questions

Are all IGCSE Co-ordinated Sciences papers compulsory?

Yes. Students must complete all papers required for their tier and qualification.

This includes the multiple-choice paper, theory paper, and either the practical test or Alternative to Practical paper.

Do all students complete practical exams?

Not always. Some centres enter students for the practical test, while others use the Alternative to Practical paper instead. Your teacher will be able to confirm which option your school has opted for.

Can I resit individual IGCSE Co-ordinated Sciences papers?

No. These qualifications are linear, which means students usually retake the full qualification rather than individual papers.

Resit rules can vary depending on your exam centre and qualification entry policies.

Conclusion

Although IGCSE Co-ordinated Sciences seems like a lot to manage at first, once you know which papers you are sitting and how they are assessed, your revision will feel much easier to plan.
