<p>In my school they don't use GPA, they use percentages.</p>
<p>What is a 91% average in GPA out of 4.0 roughly?</p>
<p>They don’t convert. There is no standard method from converting from a percentage to a 4 point scale GPA. In some circumstances, you should just list your 91% as your GPA and the college will convert it using their own scale.</p>
