Class Rank???

<p>Many colleges marked "class rank" as a important factor of admission. I have a question about that, is it rank by GPA of all seniors or anything else?</p>

<p>Class rank is calculated using the cumulative GPAs (weighted or unweighted, it varies) of everyone in your class. Most people get their rank late in their junior year or early in their senior year. Not all schools rank.</p>
