I gave the demo test and never looked back

I do not believe in referrals and i try it for myself. I went to the site and tried the demo test for 1Z0-497 exam. I must say, it exceeded my expectations on all fronts. Since i am a professional from Bhutan, i do not get much time to practice. Hence, i used to give online practice tests. It helped me to cover Oracle Database 12c Essentials syllabus well.
