I'm seeking for java2 certification. I downloaded ucertify product. Question are on right quality. Approx. 500 questions with study notes is quite enough for prepration. Challenging practice questions have been included to closely model the format, tone, topics, and difficulty of the real exam. Now they are giving 50% discount i can save big amount of money. Test simulation is good but i want few good books and study guide also. Suggest me in this regard.
