January exams are no longer available in the UK, however Edexcel continues providing January exams to centres outside the UK under the name of International A-levels. The syllabi are exactly the same as A-levels in the UK for physics. For maths, C1-C2 and C3-C4 have been combined into a single paper, the content remaining the same.
January 2014 papers will not be accessible from this website until they are made publicly available by Edexcel. However, I can send you a link for the January 2014 Edexcel Physics and Maths International A-level papers if you enter your email below.[xyz-cfm-form id=2]
