<p>Although they are weighed similarly in most cases, I from experience know that Full IB seems to require more from its students than AP. You have to do an extended essay, Internal Assessments, and CAS on top of the numerous tests you take in May. The one disadvantage of IB is that you are unable to take classes before Junior year and that is where AP should come in. I know my school sends several kids to Ivy’s and at least one is admitted to Harvard each year and it is a full IB school. Whereas other schools in my district do AP and do not have the same consistent success although stats wise the schools are similar. :)</p>
