I have read this book and did not like it at all. Not because it was badly written, but because the subject was absolutely not my favourite.
Somehow I could not get all these changes into my head (and had to do it all over again, because I failed the exam the first time...)
When I did pass the second time I gladly put it away.
I kept it, because one never knows what turn things take in life, but so far I haven't needed it again :) ( )
