A common misconception is writing is just that: writing. However, a lot of effort goes into the process of developing a piece of writing to make it presentable; and editing is a element of this process. The new GCE 'O' Level syllabus 1128 recognises this by introducing a section on editing.
This book is specially designed to develop the student's skill in identifying and editing grammatical errors. The passage are designed to expose students to a wide variety of topics so that the knowledge and language skills they acquire through reading them may be applied to the other components of their English examination, giving them a holistic improvement in the language.
