This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I checked the exam price at prometric and it only costs $125. Then I tried searching for vouchers and most of them cost at around $250. My question is, why do we bother to buy for vouchers at a higher price if we can directly pay at prometric for a cheaper cost? Is there any advantage on buying a voucher? Thanks!
