      Corrected entry option codes 05 August 2025

      For the following qualifications, we have amended the specifications to correct an entry option code:

      • A Level Biology A – H420
      • A Level Chemistry A – H432
      • A Level Chemistry B (Salters) – H433
      • A Level Physics A – H556
      • A Level Physics B (Advancing Physics) – H557

      For clarity, we’ve amended the table of entry option codes listed in section 4 – Admin. Where students are completing the practical endorsement for the first time, the entry code option is now shown correctly with the ‘A’ suffix.

      The ‘C’ entry option code is only to be used when students are carrying forward a previous result.

      This correction only applies to the specifications above. We’ve not amended the entry code options listed in our entry code booklet as these remain correct. 

      You can view and download the amended specifications from the relevant qualification pages on our website and Teach Cambridge.

      If you have any queries about this update, please call our Customer Support Centre on 01223 553998 or email science@ocr.org.uk.
