It used to be that 2100 (“triple 7s”) was considered “high enough to apply anywhere,” though now some ratchet that up to 2250 or so (conventional wisdom, or urban legend, or gossip- totally unreliable sources). In any case, 2130 is very high. Generally girls are URMs at technical schools. And 3.9 unweighted is very high!
So, why would you not see yourself as a legitimate target for Olin? Their 25-75 was listed in 2008 as being something like 2110 - 2330. For girls, acceptance rates may be higher (though scores likely will not be).
