Compared to the OCR specification (for the sciences at least), the physics specification for Edexcel seems too brief/vague, and there is a lack of detail in it for what we need to know--is there a website, or another document that covers the specification in more depth?
This is for A level by the way. At GCSE, the specification helped a lot as it was specific on what we needed to know, and the OCR specification for chemistry a level is also quite in depth, so it is quite irritating for the Edexcel physics spec to be vague in comparison...
