Thank you everyone and good luck with the coming test.
Regarding the questions, there were only 2-3 that looked hard; other ones were very and very simple. Yes it is not that easy to get maximum like it may seem after checking what other people say, but on the other hand, you can't fail it unless, of course, the corresponding book has never been opened.
I was just surprised how on many forums people say "It is a peace of cake, just look through a book before the test and you are good" - so I decided to share my opinion. It is absolutely not true and I am not sure why these rumors are so popular. Get ready for the test seriously. Spend at least one hour every day during the whole week. Well if you have PhD and graduated from the Harvard university, you probably don't need to read this book at all as you know everything already, otherwise, don't neglect it, no matter how good the tests on your mobile app or your favorite website are.
