Finally I got the result of SCEA Part 2 with the score of 88. Sun has exactly communicated the result in the 5th week after submission. I would suggest ..submit the exam and go for vacation instead of keep checking the Sun Site . When you come back, you will have some good news.
Immediately after passed the Part 1, start working on Part 2. I did some relax between these 2 exams which put me to review againthe syllabus.
For Part 3, as every SCEA says, Sun is testing whether you did the assignment. So by mistake, if you didnt address any non-func requirement, if the Question has been asked on that non-func req, its nice to mention your decision for that req and put a note that you didnt address that( if you have reason why didnt address, mention it ). This is my suggestion since I did for one non-func req and passed the exam with recently good score.
Thanks to JavaRanch Team for providing very nice discussions which helped me to understand some requirements.
