Oracle 1Z0-497 mock tests give the option to practice and attempt on the same tests as many times as I wanted. So clearly I made the most of this feature as it is the best thing to correct the mistakes and learn more about the syllabus in the simplest of manner. It is just like reading a book or watching a movie because we understand the nuances only the second time. Hence, clearing Oracle Database 12c Essentials certification exam was not at all tough for me because I went through the ordeal multiple times before giving the actual exam.
