Thank you! I was also waitlisted on March 12th. I have a 3.83 GPA (I forgot the sub-GPA calculation, but I think it was a 3.95 or something) and I got 4Q on the CASPer. I don't really have related work experience, but I had a few really unique experiences in other areas that I think helped me stand out. I also have research experience for my undergrad thesis and I am bilingual.
