Thanks for the reply. Agree about taking a minute to breathe/clear mind during exam. It can be very stressful.

I was very happy when I passed the exam. the following lesson learned could be useful.
1- Read the PM BOK deeply, try to understand every thing.
2- Read Rita's book, it is very helpful.
3- Solve as much as possible questions.
4- Manage the time during the exam.
5- Try to practice what you learn.
6- For the applicants who are the English is not their native language, there is long questions ... don't waste the time reading the question many times.
7- Focus while reading the questions.
8- If you feel tired .. take rest for 2-3 minutes then proceed.
