I got 84% and passed the exam

I practiced for 1Z0-808 Java SE 8 Programmer I every day for a few weeks on oraclestudy.com, I was able to score above 95% during that time. The last two times, I reached to 98% as well. Then I took my actual java certification exam. I found all the questions similar to what I practiced here. I got 84% and passed the exam. Thank you oraclestudy.com
