I agree with one of the reviews that all the reviews indeed look fake when glanced at, the first time.
I gave my exam day before yesterday, and passed it in my first attempt with barely a week's real prep! I had PMBOK and this book for reference. The difficulty level, structure and content are very similar to the real one.
Key things to keep in mind while attempting questions are;
1. Religiously refer to the answers/explanations after the exams. Collate the same with PMBOK.
2. Read the PMBOK first to get an idea of PM. Attempt a few exams and re-read the PMBOK. That way, you would know the kind of things you should concentrate on, rather than reading and dozing off :)
3. You should be a Project Manager first, before you follow my advise. It is very important to have actually undertaken each and every process listed in PMBOK, by yourself (even if you were not aware of the name of the process which you were involved in!),
4. Just browse through the ethics book a day or two before the exam (you would have inadvertantly followed ethics as a PM, even if you were not aware of it!),
5. I had my exam from 0530 to 0930 in the evening. Generally I have my dinner at 0630 PM on other days. Result: Was kind of hungry in the middle of the exam. Moral: Schedule your exam in a time slot you are most active at.
6. 200 questions in 4 hrs = 50-55 questions every hour. STICK TO IT. Any lags, and you won't have any "schedule compression techniques" left
7. Days before the exam, take a print of all your project's performance reports use techniques described in control costs, control schedule, change control and control scope on the reports. It will immensely help you understand and "appreciate" the concepts listed in PMBOK,
8. Be modest. PMBOK is more than enough to understand PM processes. Scordo's book will make you exam ready. All those expensive exam books are just not required.
With that said, I wish you all the very best in your exam and happy hols.
