I don’t do the AP but I do take IB, and that alone is stressful and time-consuming enough. Personally I wouldn’t recommend it unless for some reason your universities require it. I doubt that’s even possible though
I'm taking my electives as AP classes because I'm extra, though I will say many of the IB teachers at my school are understanding of the other teacher's coursework (not to say they aren't strict). I guess it's about committing all the way or not doing it at all. I'm not really sure if that helped!
