While the college websites and college admission departments of many top colleges in United States seem relaxed about the SAT-subject test scores and AP classes, the reality is that many who get accepted in the top schools in STEM programs have an impressive record of 800 in Chemistry, Physics, Biology and Math with at least one humanity subject.  They also have participated in sports, music, and drama.  The core curriculum is aggressive in introducing the science but not enough to get students ready for the three science subject test and math by the fall of their senior year.
