2.98 GPA, 300 OAT, accepted to UIWRSO
I also got an interview to PCO that I turned down, and interviewed at Nova and had to send in my 1st semester grades. I am still waiting to hear back from MCO, ICO, and SCO.
Honestly, if you are on the border and worried, hopefully you have a lot of extracuriculars and optometry experience, and then really nail the interview. Use the interview feedback section on here and be prepared for every single question. Basically just give them every reason to look past your mediocre numbers because you are impressive in other areas, and they will give you a chance.
Hope this helps!
