<p>Importance varies. For business college, you should assume essays and ECs are very important for all applicants; for others they range from less importance for high stat applicants (a bad essay can harm you, otherwise they have little impact) to very important for borderline applicants.</p>
<p>For most public schools, it’s GPA, ACT and Class rank. Essays and ECs are still important, but do not matter nearly as much as they do for private schools. </p>
<p>Public schools have to keep their numbers up for funding, where private schools do not receive funding in the first place, therefor just look for all around good applicants.</p>
