I got a letter of acceptance to UofA MPH and I was told to wait on the portal and to confirm my intent to accept. While this was happening I was interviewing for a role at Public Health Toronto and I was successful in getting the permanent full time position. But last week I turned down the job offer because the position would be starting in 1-2 months before the UofA mph. I emailed UofA as to why my status has still not updated on the portal last week and they just emailed me that I'm no longer accepted upon further review of my application... that my gpa doesn't meet the cut off. Even though they had all my documents from the start. If anyone has any advice as to what to do... would be great. I'm really down right now because I turned down the job because of this and I have no school to go to either ?
