GMTplus7 is correct regarding the elite schools’ desire for “a well rounded class.” However, each individual has to be himself, and most of us are fundamentally “well rounded” rather than “angular.” I believe the OP should continue to work conscientiously and plan carefully for college, but not alter his fundamental, personality- and values-driven ECs and activities to achieve some esoteric “ideal college qualifications.” The foregoing suggestion does NOT apply to truly focused, hard work on academics, standardized test preparation, etc. They are the most critical “must qualify” application factors, in which the OP should diligently strive to excel.
