Biology OptionsEdit

Exam-only Biology IGCSEs are available from Cambridge (CAIE) and Edexcel. (AQA certificate exams were available, but stopped after summer 2017).  

The new 9-1 GCSEs are not feasible for most external candidates. Although the new science GCSEs don't have a practical exam, OFQUAL has required that school heads sign a declaration that candidates have undertaken the core practicals for each syllabus, and the exam boards require that these are carried out in the exam centre. Very few centres will support this, so most home educators do IGCSE sciences. IGCSE sciences are well-respected and are still being used in many independent schools.  

Edexcel offer Biology or Human Biology.

CAIE offer only Biology. This syllabus seems to have more human biology content than the Edexcel 'general' Biology.

Human_Biology is on its own page.

The Edexcel specification has changed it science syllabuses to 9-1 grading, along with a few syllabus content changes. The first new syllabus exams will be summer 2019.

CAIE has added a 9-1 graded syllabus. The syllabus content is the same as that of their A*-G syllabus, and the syllabuses will run alongside each other. At some point it is possible that the A*-G syllabus option will be discontinued, but there is no news of this yet.

Cambridge (CAIE) IGCSE Biology Edit

CAIE IGCSE Biology The current specification exam code for A*-G grading is 0610. The equivalent specification for 9-1 grading is 0970. The specifications are the same, but grading differs.

Choose between Core (maximum grade C or 5, papers 1,3 and 6) and Extended (Core + Supplement; papers 2,4 and 6).

Book recommendations from HE-Exams groupEdit

Free download from iTunes of CIE Biology textbook. The link takes you to a BBC story about it. The actual downloads are available from the iTunes Stephen Pearse Foundation Store. The free material is only available in the iTunes U app on iPhone or iPad, not on a PC or windows laptop.

One parent commented:

We would recommend IGCSE Biology by D G Mackean. The author has a website, Biology Resources, with answers to all the questions in the book and additional self-assessment question sheets (and answers) that can be printed out. [Edited to note that the answers appear to be for the 2nd edition of the book, not the most recent third edition] The site also has lots of other diagrams, information about practicals etc.

The downside is that the book is very detailed and doesn't follow the order of the exam syllabus exactly.

The best way to mitigate the problem of feeling swamped is to also get IGCSE Study Guide for Biology by Dave Haynward (pub Hodder) . It summarises all the key information for each topic-key objectives, key definitions, key ideas and also has sample exam questions and examiners tips. It is a great map to help you navigate the course and make the best of the Mackean book.

Cambridge IGCSE Biology published by Collins is about a third of the thickness of Mackean, has good diagrams and review questions and can be helpful in getting a first grip on a topic area.

Edexcel IGCSE Biology 4BI1 (from Summer 2019) Edit

The old Edexcel IGCSE Biology 4BI0 had its last sitting in January 2019. The syllabus was updated to the new 9-1 grading, alongside some content changes, and now has the code, 4BI1 First exams for the new syllabus will be in summer 2019.

[ Note: The Edexcel Certificate, KBIO, was the state schools version of the IGCSE and was available until last exams in Summer 2017. 4BI0 (the IGCSE) and KBI0 had exactly the same materials and exam papers.]

Syllabus Information Edit

The 2017 spec hasn't changed much from the 2011 spec. There is a mapping document on the 2017 specification page, which describes the changes, on the exam board website, under Course Materials, then Teaching and Learning Materials tab.  

On the specification page for the 2017 syllabus you can download past papers, mark schemes and examiners' reports. There is also a scheme of work available, which is primarily for teachers, but can be useful as a guide. 

For more practice you can use past papers from the 2011 specification. The structure and some content of the exam papers might be a little different to the current syllabus, so do check and cross-reference where needed.

Textbooks for Edexcel IGCSE Biology

[This section is to be updated, as many of the textbooks listed are for the older syllabus. In the meantime, please ask for textbook recommendations on the HE exams and alternatives group ]

Edexcel IGCSE Biology (Student Book) by Philip Bradfield et al. - This is the Student Book that Edexcel specify for the '2011' specification, although it is the 2009 edition - see Edexcel Resources for confirmation of this. You will also need the Answers to the Student Book questions as these are not provided with the book, though Pearson Edexcel supply them online as a free pdf. [ Link updated 15/5/2015]

Collins International GCSE - Biology Student Book: Edexcel International GCSE - Endorsed by Pearson Edexcel as suitable for their syllabus, and published by a different company. You will need to download the answers here: answers to the IGCSE Biology Student Book as these are not provided with the book.

Hodder Edexcel International GCSE and Certificate Biology Practice Book Paperback – 28 Jun 2013, by Erica Larkcom  (Author), Roger Delpech (Author), Kathy Evans (Author) . Does not come with answers, so a member of the HE Exams group obtained them from Hodder and you can download here: Answers to Hodder Edexcel IGCSE Biology Practice book [Note: there is now a new Hodder book for the new syllabus. Info to be updated here]

It is down to personal preference which you use.  Note that Pearson Edexcel always provide answers to all questions in their Student books - sometimes on a CD-ROM that comes with the book and sometimes as a download from their site.  Collins books generally have answers to some questions, but the answers to the 'Exam-style' questions are only given in the Teacher Pack, which is sold separately at nearly £100. However, Collins have provided a pdf of the answers to the IGCSE Biology Student Book for the use of home-educating families. You can email them and ask for the answers if you explain that you are home educating, they have been sent free of charge as a PDF by email. ( File:IGCSE Edexcel Biology Student Book answers Collins 2012 edition.pdf Different members of the HE-Exams group have different preferences:

"The Collins book is less detailed, sticks closely to the specification (exactly in chronological order) and is the one I use the most when teaching my biology groups. The Edexcel/Pearson book is far more detailed than necessary but full of extra information that is very interesting. I tend to set this book as a reading homework."

You may want to purchase the Edexcel/Pearson revision guide which is only about £7 or £8 which has revision style notes and a good supply of past exam questions (answers are on the accompanying dvd)


"The Edexcel Student Book was all my son needed to study with, and he got an A*.  He found the book interesting and comprehensive, and all answers were easily available.  He just worked through it and then did past papers."

AQA Level 1/2 Certificate in Biology Edit

AQA Biology Certificate/IGCSEThis specification was available to private candidates from June 2013 until summer 2017. AQA discontinued all their Level 1/2 Certificates as the new 9-1 GCSEs in each subject become available.

Edexcel Human BiologyEdit

Please see the Human_Biology page for information on available specifications, plus a great list of resources on human biology.

Practical WorkEdit

It is not necessary to carry out practical work at home to get a top grade in the exam, but doing some practicals will, of course, help. The IGCSE exams contain questions about how certain experiments would be designed and these can be challenging, requiring you to think about factors which might affect your results.

Please see our new page all about doing Biology Practicals from home, which includes information on obtaining supplies and hints and tips.

Note that the Edexcel and CIE syllabuses for single sciences are very similar, so you can use resources for either.

There are many practicals on the GCSE and IGCSE syllabus which can easily be carried out at home - food tests, photosynthesis - growing plants in different conditions, diffusion and osmosis, examining cells under a microscope.

Nuffield Practical Biology has free 'how to do it' sheets for every practical activity on the GCSE, IGCSE and A-level syllabus. They are aimed at teachers but it's not too complicated and there is plenty of help on the home-ed exams forum if you get stuck.

Illustrated Guide to Home Biology Experiments by Robert Bruce Thompson and Barbara Fritchman Thompson - a textbook which doesn't assume any prior knowledge and is particularly good on use of a microscope. It goes up to roughly A-level standard. It can seem a but daunting but certainly gives you confidence in how to do experiments at home. It is aimed at home hobbyists and US-based high-school home-educators.

The Edexcel IGCSE Biology Teacher Support Materials are available free online and are very useful - see  - they include a list of 15 recommended practical experiments.  The Scheme of Work contains more suggestions for practical work and some links to suggested resources.  You can find the Scheme of Work on the IGCSE subject page under 'Teaching and Learning Materials'.

One parent comments:

"We are using Collins Cambridge IGCSE Biology. This also has a chapter on "Developing Experimental Skills" which covers such topics as:-

  • how much detail should I give in my description
  • what are my safety precautions
  • how do I record my observations
  • how many measurements/observations do I need to take
  • the best way to show the pattern in my results
  • best technique

etc etc for 22 pages

Having looked at the Alternative to practical paper I think this chapter is invaluable.

We also have a DVD of experiments "Shortcuts to Success" Kieran Coleman.  It is produced for the Irish Junior Certificate but we have found most of the Biology experiments useful. (Also has Chemistry and Physics on the same DVD)."

Practical Skills in Biology Slideshare show on the topic.

Seneca Learning have a course on the science practicals required for the GCSE papers. This course covers all of the detail required to answer the exam questions, and tests the students on this. It is a completely free online course!
