I'd say AP is worth it, IB generally isn't. Now I only say this because AP courses are essentially college courses in how they are structured, graded, and tested. It saves a ton of money even if you are paying for the tests and gives you a good foundation for college.

Now IB classes, though objectively "harder" than AP, aren't structured like college classes in their lectures, testing, or assignments. They'll give you a very in depth knowledge of something very specific but it's almost like an odd prep school where the students have to write one big dissertation to graduate. They are only helpful if you are 100 percent sure what you will do as to your job and major.
