Paren,
You say,
1. There is no timeline as such to pass SCEA part 2 assignment.
2. The only thing to remember is you need submit the completed assignment with 12 months from the date you have downloaded the assignment from sun website.
I feel the 2 statements contradict each other. (submitting the completed assignment is halfway thru completing, one has to give part 3 after that, which is recommended to be given within 48-72 hours after uploading)
Also which SCEA are we talking of here (the old expires Dec 2008 and will not be available after that)
Have look @
