I am currently completing my first year of the ESOL English course...at level 1. You should be at a level 3 standard before you are able to take the test. But i have revised from the book (solidly for two weeks...with my wife..who by occupation is a teacher...slight advantage 😉
After reading each section i tested myself using the individual quizes.
I found the third chapter on How Britain is Goverened the most dull, boring and difficult to understand. But once you get your head around it, its quite interesting...well so you tell yourself.
