AQA AS Chemistry questions by topic
AQA AS Chemistry (7404) is a stand-alone qualification with two papers, covering the first-year content of the A-level course. ALN indexes both papers and sorts the questions into physical, inorganic and organic chemistry, so you can concentrate on areas such as amount of substance, bonding or the halogens.
Step-by-step model answers
463 of 463 questions in this course have a model answer that walks through how to earn each mark, not just what the mark scheme lists. More are added paper by paper.
