Books that are useful

My question is two pointed. If you are a CELTA canditate, what kind of grammar terminology must be studied?
And b) Are the books offered by Cambridge University Press (and therefore CELTA people)
any good?

I really would appreciate a quick feedback. I am going to leave for a CELTA course shortly.
But have really not studied the grammar part that was discussed as my defeciency.

Thank you much. NW

I'd get hold of a decent grammar like Michael Swan's Practical English Usage, which will cover what you need for the course and beyond.
