Did all mine under Christina Chapman who makes everything fun but they are not difficult only common sense.
There are 3 altogether, Conformation and movement, Hands on and Requirements of a Dog Show Judge.
Requirements of a Dog Show Judge is a lecture followed by a paper that only requires you to tick the correct answer, not difficult at all if you are interested in dogs and have listened to the lecture.
Conformation and movement is a lecture that just required your participation no written paper.
Hands on requires you to go over a dog and they are looking for the way you handle this and the care you take with the dog, they may also ask you to point to different parts of the dog, no writing. (you do not have to say what you found and it may be a breed you do not know)
Hope that is still correct it is over 10 years since I started on this route.
