A 132 page "small format" book for the price looks expensive. Flicking through may re-inforce that view. However, if you are an overworked, or disorganised A/S level student who has left the start of their I.C.T. project too late then this might just save your life!! There is very little wasted space in the book, although the author has had to cover a range of software, so some will not apply to you - most will.
There are standard ideas on how to document the different parts of your work, but for weaker students 'to do' style lists and bullet points may work well. The main strength of the book is that it manages to break what seems like an impossible task down into chunks that students can attack.
Stronger students will know most of what is to do already, the weakest will not leave time to buy or read the text! If you're in the middle ground between these two the answer to "Is it worth it?" may be "Yes, but only for a short time!!"
This book will not make it to your shelves for long, it's designed to be used once, to do a specific job. Those who will buy will be those in need of a little handy friend to ask advice of, or to gain confidence from.
