I received the exact same email over a week ago... Results being received in mid to late May refers to the results received by the university. It sounds as though everyone should be able to see their results online by the end of the week.
Is anyone else having trouble connecting to the OGS site to check their results? I'm still waiting on my results but I haven't been able to connect all day.
I know a few people who have received rejections. People who receive rejections don't generally advertise it on the internet... it seems as though they're just updating the website as they input the results. Nothing fishy. Just slow.
