Kind of. I contacted NCARB to confirm the cost and they told me it was highly likely I would have passed if my Level 2 vignette was overturned because I got enough MC questions correct.
I got hopeful then read my jurisdiction doesn't allow verification or challenging. I also read many states won't recognize an overturned fail (think NCARB certificiate) so I didn't follow through. Fwiw while researching this I came across an old post by Coach saying it's extremely unlikely so many opt to retake it.
viewtopic.php?f=4&t=10759#wrap read the follow-up to the original post about halfway down. Someone seemed to follow through and simply got a generic response.
