There is a Facebook group: Home Education UK Exams & Alternatives, and an email group, the HE Exams Yahoogroup. It has two papers; for core, 1 hr and 2hr, and for extended, 1.5 hrs and 2.5hrs. The last sitting of Edexcel IGCSE specification 4MA0 was January 2018.
If the student wishes to have any chance of studying maths at a higher level in future, they must take the Higher tier.
They may also need to obtain a Grade 6 or above if they wish to study sciences or Computing at most colleges.
There is very little difference between the exam boards for maths GCSE, so choose whichever you can find a convenient exam centre for.
The most popular (and perhaps the most straightforward to find exam centres and resources for) is Linear GCSE maths, but all options are discussed below. Join the HE Exams community to get support from fellow home-educators. However, the syllabus content has only changed slightly.
Edexcel currently run two syllabuses Geography A and Geography B.
If you are not sure which syllabus you are studying or which exam tier (foundation or higher) you are sitting check with your teacher.
To do this would involve a lot of repetition and unnecessary work.
Do you want the option of studying maths, computing or science at A-level? Foundation Tier is intended for students who struggle with maths or who just need a maths qualification, and do not want to study maths or sciences at higher level.
A formula sheet is supplied for Edexcel IGCSE but not for CIE. IGCSE is available in the winter and summer sittings to external candidates, regardless of whether they've taken the exam before.
