GPA - Numeric/Lettered

<p>Many of you have lettered grading systems, however my school's is numbered (on a scale of 100.) What are some numeric GPAs that would be common among Harvard applicants? I just can't quite gauge how much a 3.7, 3.8, etc. is, haha.</p>

<p>I have a friend who got in early action with a 98 UW and a 109 W GPA.</p>
