An absolute MUST in my view. Lots of clear, useful tips. I particularly like the '7 deadly sins' of each of the major sections e.g. of the Methodology section, the Literature section, the Data Presentation section - for each of the major sections. I'm really pleased that I've read 3 of these booklets now, as my proposal has just gone in ... and these have been invaluable ... not only for the proposal, but will used be as my research and the thesis gets underway.
I'll go as far as saying that if you read nothing else on 'how to', this particular little gem has to be 'it'.
