Review Questions on Core Chemistry (covers entire AQA specification)

These are a set of questions for every chapter in the Core Chemistry AQA Specification for last examinations in January 2013 (the newest currently). This set of questions will cover every single detail you need to know for the exam, as the questions are structure according to the exact specification. Even if you are doing another syllabus, all syllabuses are very similar so these questions will still be of enormous help. Alternatively if you have a particular area you feel you need additional preparation on complete the relevant questions provided in this resource. Great for last minute revision the day or even the morning before an exam, or just for reconciliation and preparation. Answers will be uploaded soon.
