However, I was speaking to someone in the lessons and they've done experiments not mentioned in the book, could those experiments be in the exam, or just ones covered in the book? (In the Unit 1 test it was the one experiment in the book)
Any advise, or suggestions of books that do cover the whole spec if that one doesn't would be greatly appreciated,
Not really, because when we were doing unit 1 the teacher said quite often said "this is likely to come up in the paper, but isn't in the book" - so I know parts of the specification aren't in there, I just wanted to find out if all the experiments are.
