Psychology and political science are some of the most popular liberal arts majors by far, and any good school is going to be at least decent in both. The same goes for other generic programs like biology, English, history, and so on. If you don’t apply for a PhD – which odds are you won’t – you should be less concerned with finding the absolute best programs and more concerned with finding an overall good fit.
I recommend starting with other factors (affordability, selectivity, location/setting, size, etc.) and then narrowing down based on offerings in psych and poli sci. Try the College Search tool here on CC.
