<p>So, I'm just a little confused over this whole percentage to GPA conversion thing, considering that so many people have so many different answers. I've only ever gotten one B in high school (100-86 is an A) yet my GPA translates to 3.7. I hear others talking about how they've gotten a few Bs and their GPAs are at least 3.8. Why is that? Is it just because their definition of an A is different? (like an A is 100-90 or something?)</p>
<p>Calculating GPAs can be done in a lot of different ways.</p>
<p>If you look at unweighed GPAs, I think the difference comes from whether you are rewarded/penalized for +/-s. E.g. an A- might be a 3.7 at one school and a 4.0 at another school, and a B+ might be a 3.3 at the first school but a 3.0 at the second. </p>
<p>A lot of schools calculate weighed GPAs instead of unweighed, e.g. by adding .3 or .5 or 1 to grades in honors classes (so their maximum GPA might be 4.3 or 4.5 or 5.0 rather than 4.0).</p>
<p>Since high schools calculate GPAs in a number of different ways, colleges often recalculate the GPAs of applicants to get a more objective basis for comparison.</p>
