This is good for Edexcel but also for other specifications including AQA. It is nice and simple and breaks it up into small sections. They do ask in the exams sometimes evidence for the Big Bang theory- so do have a read!



I'm about to take my edexcel physics exam, this is very helpful to me as this subject seems to come up a lot in all the past papers.
