This year we are going to take the CAE exam in June and Pass!
I'm going to try and post links here every week to help you study outside of class. It's just not enough to come to class (sorry!) I would expect you do do at least two hours private study a week to be successful. The more time you invest the better the results. I know that you work and that you are in your last year of school but I'm sure that you can find some time in your schedules even if it's just 6 minutes a day.
Have a look at the link on the right 6 minute English. If you can spare just 6 minutes everyday, I'm sure it will help to improve your listening skills and help you get better results in June.
