The Grammar Files series consists of 5 Books, 64 pages each, for CEFR Levels: A1+ Elementary, A2 Pre-Intermediate, B1 Intermediate, B2 Upper Intermediate, C1 Advanced Each unit starts by briefly introducing a new Grammar point. Then students have to practise through a variety of grammatical exercises. These books can also be used as Time Fillers, ideal for these extra minutes when teachers have some time at the end of a lesson, or want to revise a specific Grammar point. All books in this series have also been designed to meet the requirements of any ELT exam at the appropriate level. Although Grammar is not tested directly or explicitly in most exams, it is, however, tested indirectly throughout, in the Reading, Listening, Speaking and Writing sections of any exam. Students can gain or lose points based on their command of English grammar, therefore, it would help to undertake a general review of English grammar while preparing for any English language exam.
