C12 is the older version of the current P1 and P2 papers for IAL. P1 and P2 were usually combined papers called C12. It was a combined paper of C1 and C2, which is great for revision.
Papers ending in R were the international version of the Edexcel UK papers (they are not specifically IAL), but have been included here for completeness and also because they were harder than the regular UK papers. These R papers only existed for the 2 years (2013 and 2014). You can find all the UK C1 and C2 papers by clicking C1 Papers or C2 Papers.
