Hi all,
I would like to inform you that I have passed OCMJEA, I got 144/160.
It was an excellent experience through all levels required to pass.
My Assignment was Factory Homes, I read it five times

, then I started doing the analysis for it. after that draw the diagrams.
In fact, I have faced many performance issues in real world and many many cases, so I have used best technologies to cover all these issues, also I tried to move these API's , Technologies to my assignment.
My solution was simple, clear and easy to understood.
I put 5 Risks only, but they are very important, and cover whole application.
For Essay Exam, I have faced unexpected questions (I thought all questions about NFR), but they were easy because real world experience. most of the questions were about NFR, Design Pattern used and scenarios.
I just wait 14 days to know the result (they were 2 years for me

, because I was checking the result daily

)
I got many useful information from this blog, and I am sharing my experience now to help others.
Thank you all and I wish you all the best.
Sami.
