The Diagnostic Practice in English series is written in order to expose pupils to sections tested in the English Language examinations, as well as to allow them to spot sections and grammatical components in which they are weak in. A marking scheme is also provided so pupils can gauge their ability.

Each book in the series is split into 12 practices, each covering a specific theme and specific grammatical components. Each practice includes Paper 1 and Paper 2 of the English examination. Answers with detailed explanations are provided to show pupils how the correct answer is derived.
