Curving at all schools is on a course-by-course basis. Here’s one Emory professor’s grading policy (math/CS dept) which uses curves:

ETA: This page gives a recommended grading curve for Goizueta courses.

And regardless of curves, it just doesn’t make sense for a student who needs to get a high GPA to start at a school where they’re in the bottom half by test scores.
