LITERALLY, the only studying I do is memorising the Chemrevise revision notes and then doing past paper questions. The AQA Chemistry questions are soo repetitive so memorising mark schemes helps a lot! I also note down the questions I got wrong and learn the mark schemes to them.
Where I get my Chemistry practice question:
• Past and Specimen Papers for all AQA, OCR and Edexcel
• Physics&MathsTutor
• SaveMyExams
• Ask your teacher for more questions
• A-LevelChemistry.com
