I do edexcel physics and edexcel chemistry a level if i used OCR A revision resources for physics and AQA revision resources for chemistry because they dont have the resources for edexcel would that be okay can i still use it?
To be honest this doesn't sound like a good idea. While they do overlap in a lot of areas there will be gaps and places where the syllabus differs a lot. The only time I'd recommend doing this is if you've exhausted all past paper material from edexcel and you have no choice but to use other boards. May I ask why don't you have rescources for edexcel?
