EPS The part is very badly done: a first part on PSE in general that no concrete information and is difficult to decipher as there are abbreviations and subjects "type" treated vaguely and without any explanatory diagram .
For the "education system" is even worse: there are no class! At no time was a contribution of theoretical concepts chapter by chapter. Only five councils and boat really matters which one finds all texts in all other books of its kind, but much better explained!
Finally, 16 euros for a book that does not exceed 1cm thick, full of misspellings and bad constructed: I am sorry! For me it is unusable, I have to buy another.
