Key examiner messages
Top priorities from the principal examiner before you revise
The June 2022 AQA A-Level Chemistry series represents a high-standard set of papers that thoroughly test both quantitative physical chemistry and precision in organic mechanisms.
Paper 1 proved to be demanding, requiring deep familiarity with multistep equilibria and Group 7 redox chemistry.
Paper 2 was exceptionally mathematical, featuring a heavy kinetics section including Arrhenius activation energy calculations and quantitative polymer titration.
Paper 3 blended challenging practical assessments with a highly competitive multiple-choice section.

Command word playbook
How to match each command word to the expected response style
Show formula, substitution, and unit; method marks need visible working.
Match the expected response style for “Name” questions.
Give reasons and link mechanism to outcome; each point needs a because/so chain.
Match the expected response style for “Outline” questions.
Match the expected response style for “Deduce” questions.
Match the expected response style for “Define” questions.
