Welcome to A2 Practical Skills Assessment

This page provides resources to cover the Practical Skills Assessment (PSA) (for CHM6T - Centre Assessed Route) and the Practical Skills Verification (PSV) (for CHM6X - Externally Assessed Route)
Candidates must attempt at least two tasks from PSA10, PSA11 and PSA12 (A2 Inorganic Chemistry), at least two tasks from PSA13, PSA14 and PSA15 (A2 Physical Chemistry) and at least two tasks from PSA16, PSA17 and PSA18 (A2 Organic Chemistry)
