@SashaFonn Psych is definitely as strong as Bio at the undergrad level, and both Psychology and Bio are very well regarded and top notch at Tufts as well as in the Northeast. I am just entering the Class of 2021 as a Bio/Physics major so I do not know much about SMFA combined degree or humanities, but I have a friend who is doing Art at SMFA with CS and he seems to be extremely excited for the program. Though I do not know much about humanities, I found a thread about English and Philosophy at Tufts that you may want to look at. Best of luck!
