The revise for M1 is perfect for quick time refresh on possible topics you need to brush up on. The questions are not to a ridiuclas difficult however are not easy and do test you before the exam. I found that it was useful even though I never read all the chapters, I would recomend it to you for use before starting your past papers to make the transition from textbook into past papers more easier as the questions in this book are closer to what the exam question are like compared to the textbook. However if there is one or to weeks till the exam and you want to revise I would suggest scrapping this book and just going straight to the past papers. However I will repeat myself and say it is better for a transition from textbook into past papers as the exams seem more relevant and the questions much closer to exam! I used it for this transition because I was a little lost with mechanics, However found that it did help.
