I’ll assume you’re talking about GCSEs.
I used both CGP and PhysicsandMathsTutor and they’re both good in their own way. To be honest, Physics and Maths tutor was only good for exam based revision - I focused more on content than application (which is why I think CGP is so useful)
It’s okay. Would definitely recommend the CGP Science books. They give all the information you need without any waffle. Got a 9-9 by using the revision guide heavily and creating flash cards from it.
Also FreeScienceLessons was amazing for understanding difficult concepts.
