I think the notes provided are quite good and you can easily flick to the section you want to look at. The thing that I dislike most about this is that it will use a certain term for something and indicate that there will be a footnote to give the meaning of said term. You go to the footnote and it says go buy another one of our books if you want to know what this term means which is just complete money grabbing.
Would probably not recommend. Like the comment below suggests, all the subheadings go on about purchasing the other Exam Room Notes or purchasing their mock exams. However, it does have tips on how to approach certain areas of the exam which are quite helpful.
