Now that the Summer 2023 exam series is over, I can record the Summer 2022 series (teacher have to keep them secure for 12 months). This is excellent revision for any series or mocks, as written by Edexcel and sat by students all across the country in 2022.
Solutions are my own, so may contain errors.
