When planning your AP schedule, it’s important to know which courses are considered the hardest AP classes. Difficulty depends on several factors — including pass rates, content load, and the skills required.
This guide covers:
- How we ranked the hardest AP classes
- The top hardest AP courses based on data and student feedback
- Why these classes are so challenging
- Tips for success in each
How We Ranked the Hardest AP Classes
To determine difficulty, we looked at:
- National pass rates (percentage of students scoring 3 or higher)
- Percentage of students scoring a 5
- Subject content volume and complexity
- Skills required (memorization, math, analysis, writing)
- Student workload and time commitment
Hardest AP Classes Ranked

- Very low pass rate compared to other APs
- Heavy on advanced calculus-based physics
- Requires strong math and problem-solving skills
2. AP Chemistry
- Large volume of topics and formulas
- Requires deep conceptual understanding and lab skills
3. AP Physics C: Mechanics
- Highly technical, calculus-based course
- Tests problem-solving speed and accuracy
4. AP U.S. History (APUSH)
