Hi @Christian8, you can find the answer on FAQs | SAS:
"Candidates may attempt each certification exam up to five times in a 12-month period, waiting a minimum of 14 days between attempts. Exam charges are incurred for each exam attempt. Exams that do not comply with this retake policy will be considered invalid and will not be eligible for refund and/or a certification credential.
Once a passing score is achieved on a specific exam, no further attempts are allowed on that exam*."
Best
Markus
