Your son will be one of thousands with similar stats, no matter how good, vying for places at elite schools. This year he needs to decide if he is enamored enough with Spanish to do the immersion. It will NOT get him into any schools. His decision for which HS to attend depends greatly on wanting to do the Spanish thing. Especially when compared to the enjoyment of learning through the IB system. Forget the college hunt for now. Don’t forget travel time.
