  • Correct answers for assessment

    There are so many types of questions and 510+ in number on the dbexam.com site. I began with clearing the mock tests on an alternate basis covering the syllabus together for the 1Z0-830 certificate exam. Then i gave one mock test daily. This helped me clear the Oracle exam with a very good score of at first attempt.
