Here are pandemic-era “infographics for 23 of the most popular schools that DCPS students apply to,” including the DCPS GPA associated with each.

The DCPS GPA associated with Maryland in this infographic is so low that I assume it’s some kind of typo. Regardless, it seems to me that relatively few kids from DCPS go to College Park. Penn State and Pitt are more popular, I assume because they’re a little farther from home. Other popular schools include Wisconsin, Boulder, Tulane, VT, UVM. DCTAG means DC kids really do go all over, and most flagships are within reach for an A/A- student.
