be chemistry exam ready

MESSAGE FROM OCTOBER 2022:

I appreciate a lot of people were waiting for KS3/A level/Biology/Physics resources to be released, but the reality is that this has not been possible to produce. For those that didn't know, this site has been run by one teacher over the past 6 years. It has not turned a single bit of profit (nor was it meant to), but these sites are not free to host. 
Due to the cost of living increasing, we have scaled back our service to only provide GCSE chemistry revision resources at this time. We apologise for any inconvenience caused, and hope in the future to be able to provide a larger service.

If you feel like helping out, or returning a small sum for any help I might have given, then please feel free to donate:
