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 have visited today the Oracle certification page that mentions the price of writing the OCA Java SE7 exam. The amount listed is VND 3151650, which is in the Vietnamese currency and equivalent to USD 150. Since earlier you mentioned USD 245, I wonder why Oracle keeps reducing the exam price so frequently.
