For those of you checking the portal, make sure you are using the same email that you used to apply on NursingCas. I believe that it is easier to view on a desktop/laptop than it is on a phone.
When you enter the portal, if you see "This is for admitted students only", then you are most likely still under review. You can confirm this by clicking on the "Checklist" tab between "Welcome" and "Financial Aid" at the top of the page. If you are admitted, you will see "Congratulations! You have been admitted to SMU" at the top, and "You have been admitted" a little further down as well.
I hope this helps!
