[Whistleblower]

Here are the books that I bought for my CELTA Course:

1. J. Scrivener: "Learning Teaching", Second Edition. Macmillan.

2. M. Swan: "Pratical English Usage", Third Edition. Oxford.

3. M. Parrott: "Grammer for English Language Teachers; With exercises and a key", Eleventh Printing. Cambridge University Press.

These are great resource books and really good at improving your lessons and how to teach in lessons.
