Searching for the easiest and hardest AP classes is one of the most common things students do when planning their high school schedule — and for good reason. Knowing the relative difficulty of each AP course helps you build a balanced course load that challenges you without overwhelming you.
This guide ranks AP classes from easiest to hardest based on three objective measures: exam pass rates, percentage of students scoring a 5, and the average weekly time commitment reported by students. We also explain why difficulty is personal and how to use these rankings as a starting point rather than a final answer.
How We Ranked the Easiest and Hardest AP Classes
We used three data-driven criteria to rank AP courses by difficulty:
- Pass rate (score of 3 or higher): Higher pass rates generally indicate more accessible exam content.
- Percentage scoring a 5: A lower percentage of top scores suggests the exam has a higher difficulty ceiling.
- Student-reported workload: Weekly homework hours and preparation intensity as reported in student surveys and course reviews.
No single metric tells the full story. A course with a high pass rate may still require significant study time, and a course with a low 5-rate may simply have a harsh scoring curve. We consider all three factors together to produce the most balanced ranking possible.
The Easiest AP Classes to Start With
These AP classes are frequently recommended as first AP experiences because they have higher pass rates, more manageable content volumes, and exam formats that reward straightforward study strategies.
| AP Class | Pass Rate (3+) | 5-Rate | Weekly Homework | Why It Is Approachable |
|---|---|---|---|---|
| AP Psychology | ~59% | ~18% | 3–5 hrs | Content is interesting and relatable; exam is mostly multiple choice |
| AP Human Geography | ~54% | ~15% | 3–4 hrs | Conceptual rather than formula-heavy; good intro to AP-level thinking |
| AP Environmental Science | ~53% | ~10% | 3–5 hrs | Broad survey course; less depth per topic than other sciences |
| AP Computer Science Principles | ~67% | ~12% | 3–5 hrs | Project-based; focuses on concepts rather than heavy coding |
| AP Macroeconomics | ~55% | ~19% | 3–5 hrs | Focused content area; manageable number of core concepts |
These "easier" APs are not without challenge. They still require consistent study and exam-specific preparation. But they are excellent starting points for sophomores or students new to AP-level coursework.
Moderate Difficulty AP Classes
These AP classes represent the middle ground — more demanding than entry-level APs but manageable for students who have strong foundational skills and good study habits.
| AP Class | Pass Rate (3+) | 5-Rate | Weekly Homework | Key Challenge |
|---|---|---|---|---|
| AP U.S. History | ~49% | ~12% | 5–8 hrs | Massive content volume; heavy reading and essay writing |
| AP English Language | ~56% | ~10% | 5–7 hrs | Analytical writing under timed pressure |
| AP Calculus AB | ~59% | ~20% | 5–7 hrs | Requires strong algebra and pre-calc foundation |
| AP Statistics | ~58% | ~15% | 4–6 hrs | Conceptual understanding of probability and inference |
| AP World History | ~51% | ~10% | 5–7 hrs | Broad global timeline; essay-heavy exam |
| AP Computer Science A | ~67% | ~25% | 5–7 hrs | Requires logical thinking and Java programming skills |
Most students take their first moderate AP in sophomore or junior year after gaining confidence with an entry-level AP or strong honors course.
The Hardest AP Classes and Why They Challenge Students
These are the AP classes that consistently rank as the most demanding based on pass rates, time commitment, and conceptual complexity. They are not impossible — thousands of students earn 5s every year — but they require substantial preparation and strong prerequisite skills.
| AP Class | Pass Rate (3+) | 5-Rate | Weekly Homework | Why It Is Difficult |
|---|---|---|---|---|
| AP Physics C: Mechanics | ~73% | ~30% | 7–10 hrs | Calculus-based physics; strong math skills essential |
| AP Physics C: E&M | ~67% | ~27% | 7–10 hrs | Abstract concepts; requires multivariable calculus intuition |
| AP Chemistry | ~53% | ~13% | 7–10 hrs | Dense content, lab skills, multi-step problem solving |
| AP Biology | ~64% | ~13% | 6–9 hrs | Enormous content volume; experimental design on exam |
| AP Calculus BC | ~78% | ~41% | 7–10 hrs | Fast-paced; covers two semesters of college calculus |
| AP English Literature | ~46% | ~8% | 6–8 hrs | Requires sophisticated literary analysis and essay writing |
| AP Physics 1 | ~43% | ~7% | 6–8 hrs | Conceptual depth without calculus tools; lowest pass rate of all APs |
Note that AP Calculus BC and AP Physics C have high pass rates despite being considered difficult. This is because students who self-select into these courses tend to be the strongest math students. The courses themselves are rigorous; the student population simply performs well.
Complete AP Class Difficulty Ranking
| Difficulty Tier | AP Classes |
|---|---|
| 1 — Most Accessible | Psychology, Computer Science Principles, Human Geography, Macroeconomics, Microeconomics |
| 2 — Approachable | Environmental Science, U.S. Government, Comparative Government, Spanish Language, Art History |
| 3 — Moderate | Statistics, Calculus AB, World History, English Language, Computer Science A, European History |
| 4 — Challenging | U.S. History, Biology, Calculus BC, English Literature, French Language, Chinese Language |
| 5 — Most Demanding | Chemistry, Physics C (Mechanics), Physics C (E&M), Physics 1, Physics 2 |
Use this table as a planning guide when building your multi-year AP course progression. Starting with Tier 1–2 courses and progressing toward Tier 3–5 as you develop AP-level skills is a proven strategy.
Why AP Class Difficulty Is Personal
Rankings based on aggregate data are useful but never tell the whole story. A student who loves writing may find AP English Literature far easier than AP Statistics, even though statistics has a higher pass rate. A math enthusiast may breeze through AP Calculus BC while struggling with AP U.S. History's reading demands.
Factors that affect your personal difficulty experience include your natural aptitudes and interests, the quality of the AP teacher at your school, your prerequisite preparation, and your overall course load that year. Before locking in your schedule, talk to students who have taken the specific AP class at your school with your teacher. Their experience will be more predictive than any national ranking.

Common Mistakes When Using AP Difficulty Rankings
- Avoiding all hard APs: Taking only easy APs limits both your admissions competitiveness and your college credit potential. Selective colleges expect you to attempt at least some challenging courses.
- Taking the hardest APs to impress colleges without the foundation: Enrolling in AP Physics C without completing calculus, or AP Chemistry without a strong regular chemistry background, leads to poor grades that hurt rather than help your application.
- Assuming pass rate equals personal ease: A course with a 65% pass rate is not automatically easy for you. Match the course's demands to your specific skill set.
- Ignoring the teacher factor: The same AP course can vary dramatically in difficulty depending on the teacher. A notoriously tough AP Biology teacher may make that class harder than AP Chemistry with a supportive instructor.
- Stacking all hard APs in one year: Taking AP Chemistry, AP Physics, and AP Calculus BC simultaneously is a recipe for burnout. Spread demanding courses across junior and senior year.

Frequently Asked Questions: Easiest and Hardest AP Classes
What is the easiest AP class to get a 5 on?
AP Calculus BC consistently has the highest percentage of students scoring a 5 (approximately 41%), though this is partly because strong math students self-select into the course. Among more broadly taken APs, AP Computer Science A and AP Calculus AB also have relatively high 5-rates around 20–25%.
What is the hardest AP class overall?
AP Physics 1 has the lowest pass rate of any AP exam at approximately 43%, with only about 7% of students earning a 5. Its combination of conceptual depth, problem-solving demands, and a notoriously challenging exam make it the toughest AP for most students.
Is it better to take an easy AP or no AP at all?
Taking an easier AP is almost always better than no AP. Even a Tier 1 AP demonstrates willingness to engage with advanced coursework, earns weighted GPA credit, and provides potential college credit. Taking no APs when they are available raises questions about academic ambition.
Can an AP class be easy for one student and hard for another?
Absolutely. AP U.S. History is challenging for students who dislike reading and writing but more manageable for strong readers. AP Calculus BC is demanding for students with weak algebra foundations but achievable for strong math students. Always assess difficulty relative to your own strengths.
Should I take easier APs to protect my GPA or harder APs to impress colleges?
The best strategy is a mix. Take hard APs in your strongest subjects where you can earn A's, and supplement with moderate or easier APs in areas outside your core strength. This shows both rigor and strong performance — exactly what admissions officers want to see.
