I think the Barnard rejection could be telling.
Your GPA is low on its face but you go to a private and that changes things.
I’d second the Bryn Mawr Mt Holyoke type.
But you are name brand focused but want to major in Poli Sci/ Intl Relations and frankly, I don’t think it matters.
My daughter attends a pure safety (her choice) and has already interned with the state and arguably the most recognized think tank in the country during her DC semester.
Find the right fit. You are name shopping and kids who do that have a lesser chance of picking the right school. You will be at the school, four years day after day after day.
If Scripps is the right school, you needn’t be concerned with its name (which is very good btw).
Good luck.
