Your course rigor is holding you back, but your ECs make up for it. Are you considering going ED at any of these schools. I would recommend going ED at MIT or UChicago if those are your dream schools. Your chances of admission will be doubled. Also, I would consider taking the ACT again to show schools that it’s ok that your course rigor wasn’t that hard… Your showing them that you are exceptionally smart despite your course rigor.
