If you miss it
A retake costs nothing extra with your registration, which is why sitting practice exams until you clear the line consistently is the cheapest part of preparing.
Know before you book
The candidates who pass on the first attempt treat the cut score as a rehearsal target, not a day-of surprise. Sit a full-length CKS practice exam under the real time limit, scored against the published line, and book the real exam when you clear it consistently rather than once.
