1Z0-100 Practice exams are very helpful

Oracle seems to be very tough. But after giving the 1Z0-100 mock tests on DBexam.com so many times, it seemed so much easy. My grandma used to tell me that when something seems hard, do it many times, I did and succeeded. With practice on simulated tests for 1Z0-100 Certification, it was very easy for me to give the actual exam.
