AP vs. IB: Which one is better?

In Canada there are two enrichment programs:

AP - Advanced Placement
IB - International Baccalaureate

IB is designed to be much harder than AP, but it depends a lot on the school. If you enrol in an IB program, it basically means all of your classes are advanced.  AP classes are about equally advanced, but the difference is you can choose to take some classes as AP while taking others at a regular level.

AP and IB are almost universally accepted as proof of secondary academic achievement on a higher level.

The AP and IB programs are not for every student or every school; however, if it is true academic excellence which you wish to attain, you will examine what the programs offer, and consider implementing one or the other.

In a nutshell, IB is more rigorous than AP.  Well-rounded people are more likely to succeed in IB. AP is less stressful than IB, but definitely it is still stressful. There is a greater chance that AP students could enjoy their classes and earn a higher GPA.
