<p>What's the grading scale like at Penn? My friend is taking a CIS class and 93-100 is an A (4.0) but 90-93 is an A- and only a 3.7. Is that what it's like for all classes here? Can someone give me an official breakdown, I can't seem to find one.</p>

<p>The numerical to letter grade conversion is at the discretion of the instructor/department.</p>
<p>But what numerical score out of 100 counts as a A- or a B- ?</p>
