Hi Chetan, as far as i know Sun SCEA part 2 is an assignment based exam and does not have questions to be answered like the part 1 exam. you will need to take the assignment from sun and then submit it in a given time frame and the evaluation is done on the assignment.
I am also in the same situation as you. Luckily, I got a book of Mark Cade (for the old version though) from my friend which has a sample assignment. After reading the assignment, I am thinking its important to work on this first, create a design and then validate it against the solution given by Cade in the book. For example, after reading the assignment I am getting so many doubts about various things.
I am looking to buy the book for the 5.0 version (not sure if one such thing is available).
I think preparing in such a way will correct our mistakes and also improve our confidence - this should help us in finishing the actual assignment faster - though this will take more time...
