<p>Look at what grades you have. For a specific class, does your school consider anything from a 90%-100% an “A”? This is what most colleges consider an A. So if between freshman year and Sophomore year, you had 15 classes that you got at least a 90% in, then each of those classes counts like a 4.0. So you would take 15 and times that by 4.0, then divide by 15 to get your average gpa, which is a 4.0.</p>
<p>Most colleges consider percentages 80%-89% to be a “B”. A B is worth 3.0 no matter if it was an 81% or a 89%. So if you had a B in one of those 15 classes, you would do 14x4.0 + 1x3.0 then divide by 15 to get your average gpa which would be 3.9.</p>
