Believe me, when my elder brother was giving oracle, he had gone crazy studying. This made me nervous. But, recently when he saw me preparing for oracle, he was surprised. I was just giving mock tests on dbexam.com. I prepared in a contemporary fashion to pass oracle 1Z0-062 Oracle Database 12c - Administration. He congratulated me on passing the actual exam and even referred the dbexam site to his colleagues at the office.
