Got in to two schools last year. The first one I was waitlisted, then a student backed out so I took his place. After much preparation and (almost) applying for a visa, that student came back so I was rejected. The second one, I was accepted. 2 weeks before my flight and I was all packed and ready to go, when the admissions coordinator told me that I am not qualified for that degree. I told almost everyone that I am leaving, and imagine the explaining I had to do when they saw me, still in the country, jobless.
I hope the "confuse me with someone else nightmare scenario" doesn't happen to me. ugh.
