It is lively, stimulating and commendably broad in its coverage. - John Hanks, former Chief Examiner, A level Biology. The major advantage that this publication offers over competitors lies in its everyday almost simple language and style. This is what makes it significantly different, with excellent analogies making theoretical ideas and concepts understandable to the target audience...the author`s explanations are clear and his questioning approach stimulates the reader and aids the realisation that much is left to be discovered and elucidated in biology. - Kevin Edwardson, Science Coordinator, Sheffield College.
