Personally, I got a copy of the application on my computer before they turned it into a submission on line.... I was then able to see the calculations before hand. That application is no longer available for down load, that was a couple of years ago.
I applied last years and the only time I got to see my "official" GPA calculations was when they send me the summary report of my application.
I hope I made sense there... If not, ask away and I'll try and clarify.... 😎
