The page was designed for the Edexcel IGCSE (A) Higher Tier, but the content of other syllabuses will be similar. The video solutions are no longer on YouTube but can be accessed here – you will need to create an account but there is no charge for access. On registering you will be sent an e-mail asking if I can stay in touch – if you don’t want e-mails from me you can unsubscribe straight away and keep access to the courses.
