My daughter is currently a sophomore - she was admitted with no AP classes. She had a solid A average in standard classes, and had some prior engineering coursework in high school. She also had some terrific engineering extra curriculars - and she plays a sport there (not at a high level though). She showed A LOT of interest - she applied early decision 1 and interviewed. She met the admissions counselor at her high school - she also attended the ECOS summer program the year before applying. Her ACT was in the 31 range I believe. To me it seems like you should be an easy in - but you never know what they are looking for.
