Grammar Booster is a four-level, full-colour series of grammar reference and practice books. The series is suitable for use on its own or with any Beginner, Elementary, Pre-Intermediate and Intermediate course. Grammar points are clearly presented through a fun cartoon strip featuring Jim and Tonic, two endearing cartoon characters, who not only appeal to students’ imagination, but also help them to understand and practise the grammar points presented.
