Active Grammar is a grammar reference and practice series for secondary students and university students. It is divided into three levels, corresponding to the levels of The Common European Framework of Reference for Languages (CEF). Level 1 corresponds to A1-A2, Level 2 to B1-B2, and Level 3 to C1-C2. The books give comprehensive coverage of grammar at each level, while also covering reading, composition and discussion. The books are suitable for students who are preparing for Cambridge ESOL exams.
