The past papers for the current AQA GCSE Chemistry syllabus can be found here. All the available exam past papers are listed below. As this is a relatively new syllabus, the number of past papers are limited. You can download or view the GCSE Chemistry AQA past papers and mark schemes by clicking on the links below.
You can also use past papers from the old syllabus to practice with, but be aware that some topics have been removed in the new syllabus, therefore some questions might not be relevant.
