I got in touch with our Training manager who says our low-stakes "accreditation" exams are free, and
we don't have enforcement like two week wait between (yet).
Our paid for exams are also not currently limited or retake constrained, but we're looking at industry standards
on that front too.
We want you to take some time to refresh your knowledge between exams, for best results next time,
but we currently don't make you wait any set period to try again.
