Biology A-Level Practical Endorsements

A-Level Biology Practical Endorsements

A-level students currently undertake 12 assessed practical’s (CPAC’s) when studying the A Level Biology qualification and must demonstrate five competencies and twelve skills set out by the examination boards.

The Philip Harris Technical Support Team have developed product lists to aid you organise the A-level CPAC’s.  Simply find your practical and click the view products button to see the equipment requirements:
