Questions and a PowerPoint which goes through all of topics 1 and 2 for the new GCSE course in chemistry.
There are questions at the end, which are in a points style, where students get given the sheets and have to answer the questions. There are no answers for these as I go round answering them myself, so you will need to have some chemistry knowledge. You can change the amount of points required depending on your set.
You can also just use the revision slides or revision points.
