<p>My HS's method for calculating GPA, from what I can tell, is not usual. To calculate our GPA, if it's a weighted class, and say a 91, it's a 4.1. 93, 4.3. 97, 4.7, etc. If it's unweighted, and a 91, it's a 3.1. 93, 3.3. 97, 3.7, etc. First of all, is this normal? Second, how would I go around calculating my unweighted GPA? Do I use an A=4 system, or the one my schools uses?</p>
<p>I believe you’re right: that is quite unusual.</p>
<p>But I don’t understand why you want to calculate your unweighted GPA. Is this for college applications? Your GPA, calculated in that idiosyncratic way your school uses, will be on your transcript. That’s really where admissions officers are going to look, no matter what you put on your applications. Admissions officers will also read your school profile and learn there how your school calculated your GPA. If I were in your situation, I think I’d be wary of having a number on my applications that was conspicuously different from what my school was going to report.</p>
<p>When you apply, some colleges will recalculate your GPA using their own guidelines, and some will not. Those that do not will still examine your transcript to get an idea of your level of achievement in high school–both the grades you earned and the rigor of your course load.</p>
