I have no idea what exam board I am I think it's OCR could be completely wrong, and I fined the CGP books really hard to understand is there any others you could recommend
Surely your CGP books are related to your exam board? If not, ask your teacher what exam board you are doing otherwise you will be struggling to learn everything as the content varies from each exam board.
Other than that, I can recommend you using youtube as a learning resource because there are lots of videos to help you understand. I personally though would think CGP is enough to learn stuff but if you need help, I can try explain some of the stuff to you.
