Wrote common app about music, wrote additional info about how I suffered through sophomore and junior year and explains why my grades were so bad then, had a rec from another guidance counselor about how I got through the process. Tufts supplements were good, looking to major in Peace and Justice studies, Music Engineering, and nutritional studies.

Your ACT is excellent but your GPA is poor. The stark contrast will raise questions, which you presumably explain, but that explanation better be convincing.
Also, you haven’t indicated what your junior year courses were, but the AP Psych, Gov and Enviro courses are not among the tough ones, so not overly impressive.
