Registration runs USD 125 (approximate Oracle exam fee; check official pricing), and the pass mark is ≈70% (vendor typical pass rate, subject to official change). Paying by credit card is the standard route — safe and stable for both buyer and seller. And remember the fee is per attempt: a retake costs the same again, which is why candidates drill with the 155 practice questions from Exams4sures until their margin is comfortable.

The exam sets 124 questions against 120 minutes on the clock. That pairing punishes hesitation, so train it out: set a per-question budget, flag-and-return instead of freezing, and rehearse full timed sessions in the Exams4sures engine until pacing is automatic.
