<p>How do you calculate your major GPA? Is there a minor GPA? Do you count the prerequisite classes? If I was a Bio major and I took calculus, do I count that into my GPA?</p>
<p>In my school, calculus counts towards science GPA for science majors, so it would apply to your major GPA if you were a Bio major. </p>
<p>I believe major GPA counts classes that are specialized towards your major and does not include pre-requisites which only counts towards the cumulative GPA.</p>
<p>I think it depends on the school whether classes which are required for a major but don't have that major's prefix (eg BIO 101 has the BIO prefix; MTH 150 does not) count in the major GPA. I've never heard of a minor GPA.</p>
