Upgraded my cert credential

Today I cleared my 1Z0-078 with 90%. As I am already Oracle certified professional, the certification exam experience was not new for me. Accidently I came on this site and tried demo exam, I was able to achieve only 70% and it made me to buy premium access. I really enjoyed the way your site provides the learning experience. It was very difficult for me when I cleared my past two oracle certification exams, but you site made it easy for me. Thank you dbexam.com for providing me a great practice exam experience in such a competitive price and I wish you guys all the very best for your future. Add more and more exams so it will be helpful to other candidates as well.
Thank you....
