Grammar is the essence of every language. Therefore, grammatical competence is an integral part of language learning and success in school. However, due to its technical nature, grammar has always been considered a dry, dreary and difficult area of language learning. We hope to change such perceptions with Grammar Tutor which is designed as an easy-to-use reference and guide to English grammar. It is grammar that is made simple enough to be easily understood by pupils, and at the same time sufficiently comprehensive to cover all the essentials primary school pupils require to excel in their English examination.
