They had 4 sessions (in terms of time), but another group was taking the test at the same time as my group. Perhaps 8 different groups took the test? I'm not sure though. I'm super nervous too!
I feel you- so many good students applied! I was super happy with my result too (79%), but I still don't know if I'll get into the program. Hopefully we do! (fingers crossed)
That's an awesome grade- congrats!! I got 79%, 4.0 on my prerequisites, and 4.0 overall gpa (it could change due to the classes I'm currently taking, hopefully it doesn't lol). I think that they called you once the semester is over.
