Hi! Your states look pretty good, ACT score is definitely in middle 50% (30-33 is Tufts’ ACT average) and your GPA looks great (not sure how it is unweighted, it might help you to take a look at that). Having good extracurriculars and essays really really helps with Tufts, so make sure a lot of effort goes into essays for sure. The financial aid may hinder your application a bit, as Tufts aims to meet 100% of demonstrated need, but I’m not exactly sure on how that might affect you. It looks like you have a pretty good chance, depending on if your ECs are great and essays are stellar. Good luck!!
