GPA Calculation

My highschool from 9-11 grade was wierd in reporting grades. The transcript from it which I’ve seen has the grades for individual subjects on a 100 point scale(nothing indicating what an A or anything is considered to be) yet each year also has a GPA given on a 4 point scale with not indication of how it is determined or what weighting is used. Anyway, I doubt any of this is too important anyway since it was a Catholic School and thus had religion included in figuring the GPA. Does anyone have any idea as to how colleges would go about recalculating the GPA? I’ve seen threads like this before yet none of them were too conclusive. I’m specifically interested in how Cornell and Harvey Mudd would go about recalculating the GPA. Do they just take and average of the grades on a 100 point scale or do they recalculate it on a 4.0 scale?

<p>I've been meaning to ask the same question. I'm a Canadian student, and up here, high schools don't calculate a GPA. We just get marks out of 100 for each course. I don't understand how it's calculated, and what "weighted" and "unweighted" GPAs are. Can anyone explain?</p>

<p>It varies between high schools, but generally, GPA is grade point average and the scale for regular classes goes like this:</p>

<p>A - 4.0
B - 3.0
C - 2.0</p>

<p>If you have AP courses, then you also have a "weighted" GPA in which the harder classes are weighted so a lower grade is the same as a higher grade in an easier class:</p>

<p>A - 5.0
B - 4.0
C - 3.0</p>

<p>Your GPA, of course, is the average (mean) of all the grade points you've received for all clases - usually one for each semester when the school uses a semester system.</p>
