<p>Also there are a number of College Search Tools like “Supermatch” here and on the College Board site etc.
Put your criteria (SAT/ACT, GPA, location, majors, city/rural, size, etc) into those and get some ideas. Also find out what schools are strong in Poli Sci and International Affairs and see how those match the first set.
Also like others have said, what can your family afford? Do you need to look for merit scholarships?</p>
