Pass score vs pass rate

Two different numbers that get mixed up constantly.

Pass score (cut score)

The scaled score the vendor publishes. For the Java SE 17 Developer it is 68%. This is the number you can actually prepare against, and it is the one that decides your result on exam day.

Pass rate (percentage of candidates)

The share of candidates who pass. Oracle generally does not publish this for individual exams, and the numbers you find online usually come from candidate self-reported surveys. We would rather tell you nothing than tell you a figure we cannot source.

Where you lose points

The exam is not scored flat. Each domain carries its own weight, so a domain where you lose everything can sink a score that looks fine on paper.
