This is an excellent guide with unmissable pieces of advice on how to write proper essays from the first line of the introduction to the last line of the conclusion. It guides the reader through everything a respectable writer has to think about when envisioning, planning, writing up and copy-editing their essay.
This guidebook is a great bargain with an excellent content - cheap price does not mean cheap quality at all here.
However, there is no real need to buy this book since one can search the title online to find a very similar content for free on the web, by the same author.
Unless one is desperate to get their hands on a hard and well-bound copy, the online version is perfectly sensible and will be of similarly excellent use to any student preparing their essay, in whatever discipline that is.
