Numeric grades to GPA

<p>Does anyone know how colleges actually calculate GPA?</p>

<p>There is a lot of literature but I haven't found anything conclusive.</p>

<p>My son's school does not provide letter grades - only numeric grades. Allow me to provide an example:</p>

<p>Assume he has 5 classes in a semester with the following grades:</p>

<p>96
93
89
87
86</p>

<p>If I take an average of that, it is 90.2 and translate that to the most commonly accepted GPA scale, it would be a 4.0. However, if take the following:</p>

<p>96 --> 4.0
93 --> 4.0
89 --> 3.0
87 --> 3.0
86 --> 3.0</p>

<p>And average the GPA, it is 3.4. A BIG difference.</p>

<p>Additionally, in a couple of his classes, he is automatically awarded an additional 7 points to his final average. So the above would actually be:</p>

<p>Final Course Average<br>
89
92
82
80
79</p>

96
93
89
87
86</p>

<p>How do colleges view all of the above and what methodology will they use to calculate the GPA? Do they ever make their methods public? Has anyone recently gone through it?</p>

<p>Thanks in advance.</p>

<p>Regards,</p>

<p>It looks as though you have an unweighted GPA and a weighted one (with the extra 7 points). Colleges will look at both. And the GPA will be computed as you calculated, a 3.4 based on each course being worth the same number of credits.</p>

<p>The number mapping can vary - my daughter’s college uses this mapping for her college GPA -
A - 93-100 - 4.0
A minus - 90-93 - 3.667
B plus - 86-90 - 3.333
B - 83-86 - 3.0</p>

<p>However her high school used this mapping for their GPA -</p>

<p>A - 95-100 - 4.0
A minus - 90-94 - 3.75
B plus - 87-89 - 3.5
B - 83-86 - 3.25</p>

<p>I am betting that different colleges and highs schools use many different mappings - so I don’t think the answer is going to be uniform. </p>

<p>And yes, you map and weigh each grade first and then average the results to get the GPA!</p>
