Note that I only skimmed the pages since I had a clear image of what I was looking for. Most topics, like the revision part or the planning part, were quite obvious. I could take lots of notes on the first chapter (Interpretation of the question), though, and there were parts which I knew and understood but still wrote down to remember them later on. If you have little experice in writing essays, then you should read the whole book thouroughly. Afterwards, you know how to do it since it´s an exemplary guide.
