Agree with looking at other programs that are still taking applications…@eyemgh included two great suggestions.
Also, you might want to talk with Pomona as well as WashU/CalTech/Dartmouth about their arranged programs with respect to getting into the second program as well as what financial aid usually looks like. There are some who prefer the Dartmouth 2-1-1-1 program because students finish senior year with their college friends and their first year at Dartmouth is when many juniors are going abroad, so they’re not missing their friends and activities they would have normally done.
