Does anyone know how college reconfigure GPA's

I know that colleges weigh GPA’s themselves, but does anyone know any specifics on certain schools???

<p>One of my son's friends works in the admissions office at Emory. As understand it, Emory calculates its own gpa for admissions purposes, using a 4.0=A scale; it excludes things like gym and other lightweight courses, like cooking, etc.; and then factors in a weight for difficulty of curriculum.</p>

<p>it all depends on the school you're applying to!</p>
