Supplementary

New Plus is devoted to skills development. Ranging from Beginners to Upper-intermediate, the four communication skills and subskills are carefully developed through different topics.

As the title suggests, this series provides extra grammar and vocabulary practice at level B1 and B2. With a variety of explanations and exercise, these books are especially useful when preparing for exams.

The World of Grammar & Vocabulary is a carefully graded grammar series for teenagers consisting of seven books (from A1.1 to C1/C2). 

Use of English B2 systematically teaches grammar and vocabulary and helps students develop all the skills necessary to succeed in any examination.
