I have been planning to take the SCEA exam as a New Year's resolution, and yesterday I got an email from Sun with an offer for a free retake with any voucher. I have been studying for months, but have been reluctant to take the exam because I'm not sure I'm prepared, and don't want to blow $300. Now I can take the exam, maybe I'll pass, and if not, I'll know what the questions and the exam look like, and can try it again. Sounds good to me.
I called the Sun rep and signed up for a voucher this morning. I should have the voucher by tomorrow, and will register for the exam in a couple weeks. I'll let you know how it goes. If you want the Sun reps phone number or email you can PM me.
