Very good point. IB is rigorous, more standardized than almost anything else in the US (probably only A-Levels/AICE is more standardized), and broad, but also pretty rigid (IMO). That may or may not be a problem given your point of view. Speaking as someone who despised taking foreign language classes during HS (but later and now became/am interested in one), I’m not a big fan of the rigidity of IB.
