Chemistry is a subject studied on its own at A Level and beyond. At GCSE and below most people study chemistry topics as part of a general science course, while others will study chemistry as a separate science at GCSE. So most people studying at school and above will find something useful here to help with their revision.
Our revision notes are arranged both by exam level and then by topic area to make it easy to find exactly what you want to find. Clicking on an exam level will produce all the notes categorised under that level, while choosing a topic area will provide a list of notes in that area.
