As a retired industrial chemist, my main interest was in keeping my knowledge up to date and to find new areas of knowledge that I did not have previously. For anyone considering studying chemistry, and I hope there are many, it was a good starter course providing a background to some of the many topics covered by the general term 'chemistry'. For a beginner, the glossary is essential, as is regular reference to online sources for clarification of other terms used. This would be no more than would be expected of a student studying any serious subject. Overall, an enjoyable course and well worth the time invested in it. Thank you Leeds University and FutureLearn.
