Is it true that vouchers for SCEA part 2 are not sold and we have to buy this online from Sun's site?
You will have to purchase one from a sun training center or something equivalent and you have to pass Part 1 so that they can sell the exam to you. There is no voucher as such. It will take about a week to gain you access to the assignment and you can submit it whenever you like. After this you purchase a voucher for part 3 and finish it off. Good luck
