<p>So what's the difference and how is each calculated?</p>
<p>Depends on the school. Mine, for example, adds 5 points to every honors/AP class a student takes. That being said, weighted GPAs tend to be higher than unweighted ones.</p>
<p>My school does something similar to hgates92. My School adds 0.5 for every honors class and adds 1.0 for every AP.</p>
<p>Honors aren’t offered. AP/IB get 1.1 weighting.
A=4.4/4
B=3.3/3
C=2.2/2
D=1.1/1
F=0</p>
<p>It’s different for every school/district.</p>
<p>My old school in Washington State:</p>
<p>A: 4 (honors), 5 (AP)
B: 3, 4
C: 2, 3
D: 1, 2
F: 0, 1</p>
<p>Current school in Texas:</p>
<p>A: 4 (academic), 5 (Pre-AP and AP)
B: 3, 4
C: 2, 3
D: 1, 2
F: 0, 1</p>
<p>IB School in California</p>
<p>Regular classes (non-honor/non-AP/non-IB)
A=4
B=3
C=2
D=1
F=0</p>
<p>IB/AP Classes
A=5
B=4
C=3
D=2
F=1</p>
<p>that’s for weighed. unweighed, ALL A’s are 4’s, B’s are 3’s and so forth.</p>
<p>They are both calculated by adding up each point value from each class and then dividing the sum by total number of classes taken.</p>
<p>The difference is that a weighted GPA considers the rigor of a course when tabulating the average; the idea is that a B+ in a weighted course is roughly equivalent to an A in a regular course, or something to that effect.</p>
<p>A weighted GPA is, I believe, a more accurate prediction of a student’s abilities (when weighted accurately). The unweighted GPA is good for finding out how many As you’ve gotten throughout high school.</p>
