<p>Do colleges calculate UW GPA using your quarter grades or your semester ones?</p>
<p>It depends what calendar system your school uses. If they use the semester system, colleges will never see quarter grades.</p>
<p>My school supplies quarter, semester, and year grades for colleges to use at their discretion</p>
<p>In that case, I suggest you call the admin office and ask. They might say they don’t care, in which case I would supply them with the best grades possible.</p>
