For current juniors and other future applicants looking at this thread, here are some updates:
I raised my ACT to a 33 C and 34 superscore
I got into Girls Who Code and the UChicago summer program, and did both!
I ended up applying to no STEM schools… save for Case and Purdue… though I’m still planning on studying mathematics as a major. Ah, how drastically your ambitions change throughout high school. I went from art to fashion to marketing to business to engineering and now finally to math and literature. Don’t be too stressed about not knowing what you want to do in college throughout high school.
I will be attending the University of Chicago in the fall of 2017. 
notice how it wasn’t even a school I considered when I made this thread? don’t get too obsessed with schools. your interests will change. even during senior year.
