*** Question about UMinn Status on their Portal

My D is a transfer applicant to UMinn. Initially, on the portal, she was “Waitlisted” and then being “Rejected” 3 weeks ago.

After she sent her updated transcript to UMinn 2 weeks ago with her better winter 2019 grades, her status now changed to “Your application is being very carefully considered”.

Does anyone has any idea why a “Rejected” turned into “Your application is being very carefully considered”? Is this a good sign? Appreciate if anyone got an insight

Did anyone get the above experience? It’s ~3 more weeks to go before D need to make a decision…
