Cleared 1Z0-052 with 82% is a blessing to me, it seems. I secured 86% in Oracle Database - Advanced PL/SQL certification exam on the second attempt. The first attempt was a major fiasco. I lost hope but landing on was like a light at the end of the tunnel. It gave me the confidence to appear in the Oracle exam again. The practice tests for 1Z0-148 are designed to give the feel of giving the real Oracle exam. When you give the tests, you realize that they are premium and must have been designed by Oracle consultants. Because equal weights have been given to all the topics and maximum syllabus is covered in the practice tests.
