I am a non-native speaker and will be taking CELTA in September from UK. I really don't know from where to begin. Although I am referring to Michael Swan and text book by Harmer, but still I don't know what actually the requirement is, as English is very vast. I have just been told to read five chapters from Harmer, grammar by Michael Swan and to collect picture cuttings etc if possible. But I don't what to collect as there are number of topics.
Can anyone help me out to solve the following problems:
1. What material I should carry with me?
2. What topics I need to study so to avoid confusion (English is vast).
3. Any extra reference material required?
4. What the first few days will be like - what I have to teach, little information related to the first two assignments?

Thanks
