My fellow College Coach admissions consultants and I get asked quite a few questions every year about high school course selection and college applications. Colleges want to see you challenge yourself as much as possible in the context of your high school, and will not compare curriculum options across high schools. The majority of colleges do not have a preference between AP and IB classes, so you should instead focus on challenging yourself as much as possible with the classes available to you at your school.
The Advanced Placement (AP) Program
The AP program offers students a challenging, fast-paced learning environment. Generally taken in junior and senior year, students can pick which individual subjects to take at the AP level depending on what is offered at their school.
