There are six papers for Combined Science, two for each discipline: Physics, Chemistry and Biology.
A formula sheet for Physics will be provided for Combined Science exams.
Edexcel Combined Science has the following structure:
Combined Science is a double award, meaning you’ll receive two final grades (eg, 6-7)
There are six papers, two for each of Chemistry, Physics and Biology.
The papers are all 1 hour and 10 minutes long and worth 60 marks each.
The papers are equally weighted with a total of 360 marks available.
You can take the Higher or Foundation tier, but must take the same for all papers.

Edexcel Combined Science is split into Higher and Foundation tiers, depending on your level.
Covers the core topics you need to know and excludes more complex or demanding areas.
In Foundation Combined Science, you can achieve a maximum grade of 5-5.
The higher tier covers both core and more advanced topics across the curriculum.
For Higher tier Combined Science, you can achieve a maximum grade of 9-9 - the highest possible grade.
The lowest grade you can get is a 4-4, or a 4-3 for students who just miss a 4-4.
Your school will place you in the correct tier based on your performance in Year 9. Sometimes, students may be moved up or down a tier during Year 10 or 11.
Edexcel requires all Combined Science exams to be taken at the same level, so you cannot do Higher for one part and Foundation for another.
Yes! It’s been confirmed that equation sheets will continue to be provided for Edexcel Combined Science.
The sheet will cover key formulas used for Physics. The formula sheet includes key equations needed for both the Foundation and Higher tiers.

It’s important to remember that the exact grade boundaries for your GCSE exams will change every year.
Exam boards adjust the grade boundaries after an exam has happened, depending on how advanced the exam content was and how the cohort performed.
This is so students don’t have an advantage or disadvantage because of the year they took the paper. For example, if your paper were harder, grade boundaries would be lowered so that a grade 5 reflects the same level of knowledge as in previous years.
Let’s take a look at the grade boundaries for Edexcel Combined Science from 2024 to get a sense of how grades are awarded:

Remember, these won’t be the exact grade boundaries, but should give you a sense of how many marks to aim for to hit your target grades.

With Combined Science giving you two grades, it can be confusing to understand whether you’ve passed or not if one of your marks is lower than a 4.
So, is a 4-3 a pass for GCSE Combined Science?
It’s important to understand that your grade is based on your overall mark across the three subjects. You can only get either the same grade (5-5) or adjacent grades (5-4), to reflect your performance across the papers.
A 4-3 would not count as a full pass. You have one pass and one fail. The best thing to do is check with your school or college to determine whether you need to resit or not to carry on with your choice of post-16 education.
Practising with past papers and mark schemes is one of the most effective ways to prepare for GCSE Combined Science.
Past papers help you understand question styles, see how marks are awarded, and build confidence with real exam timing and structure.
Head to the Edexcel website to find past papers and mark schemes from previous GCSE Combined Science exams.
Combined Science papers cover a range of topics. You’ll need a thorough understanding of each to achieve top marks, so make sure you revise any areas you find tricky ahead of the exams.

Natural selection and genetic modification
Health, disease and the development of medicines

The assessment objectives for GCSE Combined Science are set by Ofqual, the exams regulator, and are consistent across exam boards.
Examiners are looking for the following in your exam papers:
AO1: Demonstrate knowledge and understanding of scientific ideas; scientific techniques and procedures
AO2: Apply knowledge and understanding of scientific ideas; scientific enquiry, techniques and procedures
AO3: Analyse information and ideas to interpret and evaluate; make judgments and draw conclusions; develop and improve experimental procedures
To prepare for Combined Science exams, you’ll need to start revising early to make sure you’re confident covering all the key topics.
Don’t miss out on marks for questions asking you to state or define terms. Make sure you get your head around the key vocab, definitions and units. You can use flashcards to help you memorise key terms and quiz yourself.
The best way to prepare? Practise like it’s test day. Practising exam questions from past papers and checking your answers will help you get used to the question format and understand how to get top marks. You can also take a whole test and practise under timed conditions too, to build confidence for the real thing.
It’s a good idea to try a mix of revision tactics. From flashcards to teaching others, a mix will help learning to stick. Studying little and often will also help you avoid fatigue and burnout.
Assessment objectives 2 and 3 are asking you to apply what you know to analyse and draw conclusions. When you learn a new concept, try asking yourself: how can I apply this in a different scenario? Or what assumptions or errors might affect this conclusion?
After each mock or practice paper you take, identify the topics or question types you struggle with, then prioritise those in your next revision cycle. Over time, your weak areas will shrink and your confidence will grow!
There you have it - everything you need to know for Edexcel Combined Science. Use this guide to help you plan your revision and make sure you’re thoroughly prepared for your GCSE exams. Good luck!
