I am studying to get certified as soon as the announcement is made, I really struggle many times to understand what the author wants to say, as beyond the terminology used to describe some instrument, etc., it strays from the topic and where the answer should be a size A, you suddenly find yourself writing 1-1.5 pages more just because it keeps saying things that could have been left out.

I have to read each question and underline the important parts because in many answers it goes off topic and analyzes too much without being asked by the question. But overall, you manage to get to the point.

No one, in the end, can write a book in simple words about expertise. Neither this one, nor the other. Too bad for the market...
