You will also find it useful to do other study apart from class review: extra work on thii that you find difficult.

Also, you simply need to hear, read, write and speak as much English as possible. Here I some suggestions:

Ø  do an adult education course;

Ø  join a social club, or a community service organisation;

Ø  use every opportunity where appropriate to talk to native speakers;

Ø  read at the supermarket, in the street, in offices and shops;

Ø  use a detailed TV guide to gain more information about a programme;

Ø  dial-a-robot — work through the recorded messages in the phone book;

Ø  telephone for transport information: specific buses, trains, flights;

Ø  telephone for travel information: costs of journeys, accommodation.
