UPDATE: Papers and mark schemes are now available from the maths papers and physics papers pages.
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]
