I completed an IB program at a local high school (and also did chorus, incidentally). I'd love for my kids to do it too. The emphasis on epistemology and close text analysis seems even more important now with AI everywhere. My kids are still young, so I don't know what the specific tradeoffs are for AP courses now, but I don't think IB held me back from any STEM opportunities (e.g., I took AP Calc BC as a junior).
