regarding ocr science revision?

  hiya im taking a yr10 ocr science b1, b2, b3, c1, c2, c3, p1, p2, p3 and ive brough a revision book called 'collins new gcse science and additional science' revision guide? should i revise using this book and is it relevant for my upcoming tests?

These revision guides normally specify what they're designed to cover. Does it not say somewhere in the small print? But in any case, by and large it should be relevant and useful.
