<p>I still say that these various GPA scales mandate a standardized test. Even with recalculating, there is no sure fire way of comparing different GPA scales. No one has mentioned any kind of magical conversion scale that equates the GPAs from different schools. Just from some of these posts, you can see that an A is a 90 or above at some schools and a 94 or above at others. So a 91 would be a 4.0 in some places and a 3.0 at others. Standardized tests, although flawed, smooth out these differences since everyone is taking the same test. Until there is a universal GPA scale, standardized tests will be necessary in my opinion.</p>
