<p>Many US high schools have minimum requirements for graduation. For example, see: [Stuyvesant</a> High School](<a href=“http://stuy.enschool.org/academics/grad_require1.jsp]Stuyvesant”>http://stuy.enschool.org/academics/grad_require1.jsp). Not every student is interested in all the classes they must take. And for the record, many colleges recalculate your GPA without classes such as gym (your sport), chorus, drama etc.</p>
