A full timed practice session can help you decide when to move on, when to return, and how much buffer to reserve for a final check.
The passing score for DES-1B21 is 63%, and the official exam fee is $230 USD. Because a retake requires paying the exam fee again, use timed practice results as a readiness check before scheduling your next attempt.
