Hi,
I hope you were ganted the upload rights in the meantime.
For taking part III you will first have to buy a voucher for it at sun.com or a local subsidiary, if you haven't already.
Then you will have to schedule an appointment with a
testing centre and finally sit on the part III of the exam.
Parts II and III will be graded together.
If you like you may also have a look at
JavaRanch SCEA FAQ.
Good luck!
Stefan
