What is the Hardest AP Class?

High school students planning for college and hoping to stand out on college applications should consider taking Advanced Placement (AP) classes. Designed to give students a taste of college-level study, AP courses are more challenging than the average high school class. College boards take them into consideration when evaluating college applications, and colleges may also use AP exam results to award college credit or place students in advanced courses once their college career begins. This strategy allows students to get a head start on their college education.

The AP program offers 38 courses, some of which are more difficult than others. While harder to pass, difficult AP classes like Physics, Statistics, and Human Geography look great on college applications if students do well on the exams. These exams are scored on a scale from 1 to 5, with 3 being a pass and 5 being the highest.

Below are the 10 most difficult AP classes, broken down by passing rates. Bear in mind that many of the classes listed here are core classes, taken by many students with a range of skill levels. A specialized class like Calculus is harder than Human Geography, but also attracts students who have higher-than-normal math skills. Place students with less advanced math skills in Calculus and they may struggle more than they would in English or Geography. Ultimately, the most difficult AP classes are the ones in which you don’t have a background in the course material and core concepts – challenges which can be overcome with dedicated study and the help of a talented tutor.

World History

AP World History covers nine distinct eras of world history starting at 1200 C.E. and ending just before modern times.
