The Grammar Files series consists of 4 Books, 64 pages each,
for CEF Levels: A1 - A2 - B1 - B2.

This book consists of 30 two-page units, that deal with the
most important Grammar points. Each unit starts by briefly
introducing the new Grammar point and then students have to
practise a variety of exercises.

These books can also be used as time fillers; perfect for
when teachers have some extra time at the end of a lesson,
or want to revise a specific Grammar point.

Levels B1, and B2 have also been written for students who
are planning to take the IELTS exam. Although Grammar is
not tested directly on the IELTS, it is tested indirectly in the
Speaking and Writing sections of the exam. You can gain or
lose points based on your command of English grammar.
Therefore, it would help to undertake a general review of
English grammar while preparing for the IELTS.
