Any similar folders for math, physics and English?Unfortunately, I could only find the Third edition, here's a link to that: https://www.gceguide.xyz/files/e-books/igcse/IGCSE Chemistry Work Book by Richard Harwood.pdf
Also, check out this Google drive, it is filled with extremely useful Chemistry resources: https://drive.google.com/drive/u/0/folders/1-ESL4xz94f_veCEQkHshIn12WXvJZaxN
And here's one for Biology, if you take it: https://drive.google.com/drive/u/0/folders/1-KRwrXmPDAYyJClfFcHv3dNCHzhPF8Cj
These resources are truly helpful, I really recommend using them as part of your revision.
All the best!
