I've not seen a better summary of chemical tests. Beautifully laid out and summarised. Has the content you need.
Nicely laid out slides, but no real useful content that isn't mostly just copy paste from the specification and write the answer.
These are really useful resources, they have really helped me understand all the topics that are covered. Would highly recommend!
