Ditto after going through it once just by reading whilst I passed the tests I didnt really understand or remember what was what. So i went through the stages again and wrote it down in my own words my understanding which helped me retain the info better.

That said the final review on verbs is very tough (or at least I found it so) especially given the teaching of Transitive/intransitive verbs is very basic and the final review there are some complex examples of both

I also found as a teaching tool is to guess some of the answers and then once i guessed correctly look at the sentence again to identify why it was correct

That said this isnt an english exam we are trying to achieve a pass in once credited you will be using the qualification to teach English to others so with that in mind lesson preparation for the  course will be down to you
