Other colleges on our list you may want to look at: U of Richmond, William and Mary, (check culture/waspiness of the latter). One thing I am advising my son is that if you have an idea of what you want to go into and/or where you want to live post grad, recruiting and job offers will be more skewed towards the local area of the university. So if you def. want poli sci, you’d have more intership/recruitment opportunities at Georgetown for example. I don’t think this should be the deciding factor, because college is also a great time to explore a new geographical area for 4 years, but it’s just something to consider. Be picky! You should! And yes absolutely consider cost if you are going to grad school for sure. If your parents will take any leftover undergrad funds and put them towards your grad school, that’s HUGE. Save yourself as much student debt as possible. With your high score you could get good some merit aid from some schools.
Given your stats, you have a decent shot at $30,000 merit from Tulane, but you must show interest, i.e., tour there and interview there, express enthusiasm for NOLA! That would leave $$$ for law school and checks the boxes of warm climate and left leaning, fun city. WashU also is big on demonstrated interest but will not provide that kind of merit unless you apply for one of their scholarships and get it. George Washington University in D.C. is expensive but well known for their Elliot School of International Affairs. Good luck!
