If advanced exam can be given once in 7 days, why am I getting different date ?
Can you send us a screenshot showing this?
It should be once every 7 days, so I would email certification@alteryx.com. to get it fixed!
If you're taking the certification test for Designer Desktop: Core or Advanced,
reach out to Certification@alteryx.com

9. Can I retest if I do not pass? How many times can I retest? Is there a waiting period?
You can retest any of the certifications an unlimited number of times!
With the exception of the Expert and Predictive Master exams, all other exams allow for one new attempt every 7 days. You have an unlimited number of attempts, although you must wait the full 7 days between each attempt.
For the Expert and Predictive Master exams, you must wait 2 months between your first and second attempt and 3 months for subsequent attempts.
