Please look at the corrections I made to your post above. Some of them might give you a clue as to why you weren't accepted for a CELTA. You failed to start most of the sentences with a capital letter, you put a space before several commas and full stops, and you failed to leave a space after a full stop several times. The basic errors you made are a little worrying for someone who has already been teaching English for 6 years.
