Every AP Course Ranked by Difficulty — Pass Rates, Workload, and What to Expect
Ranking AP courses by difficulty is useful — but only if the ranking is honest. Pass rates give you the most objective data point: they measure how real students actually performed, not how hard the curriculum looks on paper. This guide uses pass rate data alongside workload and conceptual difficulty to rank every major AP exam.
One caveat worth stating upfront: difficulty is personal. A student who loves writing will find AP US History easier than AP Chemistry regardless of the numbers. Use this as a starting point, not a verdict.
How to Read This Guide
- Pass rate = % of students scoring 3 or higher (College Board data, 2022–2024 average)
- Five-rate = % of students scoring a 5
- Workload = estimated weekly study time to pass with a 3+
Hardest AP Exams
AP Physics 1
Pass rate: ~45% · Five-rate: 14% · Workload: High
AP Physics 1 consistently has the lowest pass rate of any widely taken AP exam. The difficulty is conceptual, not computational — the exam tests whether you understand why physics works, not just how to plug numbers into equations. Students who coast on formula memorization without building intuition fail this exam at a high rate.
The multi-select MC format adds difficulty: 5 questions require two correct answers, with no partial credit. If you get one right and one wrong, you earn zero.
What to expect: heavy emphasis on free-body diagrams, Newton's laws, energy conservation, and circular motion. FRQ questions often involve experimental design and justification, not just calculation.
AP Chemistry
Pass rate: ~55% · Five-rate: 11% · Workload: Very High
AP Chemistry demands mathematical precision and conceptual depth simultaneously. The no-calculator MC section catches many students off guard — stoichiometry, equilibrium, and thermodynamics calculations must be done by hand or with mental math.
The FRQ section includes both quantitative and qualitative questions. Strong lab knowledge helps, but the exam is now more focused on analysis than pure recall.
AP Physics C: Mechanics
Pass rate: ~55% · Five-rate: ~35% · Workload: Very High
AP Physics C is calculus-based and significantly more mathematically rigorous than Physics 1. The pass rate looks comparable to AP Chem, but Physics C self-selects a stronger student pool — students who take it are generally already strong in math and science. If you're considering Physics C without having solid calculus skills, reconsider.
AP English Literature
Pass rate: ~57% · Five-rate: ~9% · Workload: Moderate-High
AP Lit has the lowest five-rate of the English AP exams and one of the lower five-rates overall. The exam is largely essay-based, and the poetry analysis question trips up many students who haven't practiced close reading under time pressure. The open-ended essay — where you choose your own literary work — rewards students who've read widely.
AP US History (APUSH)
Pass rate: ~54% · Five-rate: 13% · Workload: High
APUSH covers roughly 500 years of American history across four essay formats (SAQ, DBQ, LEQ, plus MC). The DBQ in particular separates high scorers from average ones — it requires sourcing, contextualization, corroboration, and historical argument in a single essay. Students who approach it as a fact-recall exam consistently underperform.
AP European History
Pass rate: ~54% · Five-rate: 14% · Workload: High
Nearly identical structure to APUSH. The content is arguably more conceptually dense (Renaissance through Cold War Europe in a single course), but the lower total test-taking population means fewer data points for comparison. Expect the same DBQ demands as APUSH.
Moderately Hard AP Exams
AP Biology
Pass rate: ~65% · Five-rate: 14% · Workload: High
AP Bio is content-heavy and data-analysis focused. The modern AP Bio exam is less about memorizing the Krebs cycle and more about interpreting experimental results, understanding evolution across multiple organizational levels, and applying concepts to novel scenarios. The content breadth is genuinely wide — cell biology, genetics, ecology, evolution, and physiology all appear.
AP Calculus AB
Pass rate: ~59% · Five-rate: 22% · Workload: Moderate-High
AP Calc AB is moderately difficult with a notably high five-rate (22%). Students who build genuine understanding of derivatives, integrals, and the Fundamental Theorem tend to do well. Students who memorize procedures without understanding why they work get caught on the FRQs. The curve is generous — a 5 requires only about 65% of composite points.

AP Statistics
Pass rate: ~60% · Five-rate: 16% · Workload: Moderate
AP Stats is methodical rather than algorithmically complex. The challenge is precision: knowing the exact language for confidence intervals, writing complete conditions checks, and interpreting p-values without overstating conclusions. Students who are sloppy with statistical language leave consistent points on the table even when their math is correct.
AP English Language
Pass rate: ~59% · Five-rate: 12% · Workload: Moderate
AP Lang rewards clear, analytical writing over literary depth. Three essays in 2 hours and 15 minutes — synthesis, rhetorical analysis, and argument — requires both fluency and stamina. The rhetorical analysis essay in particular is a skill that needs to be practiced before exam day, not figured out during.
AP World History
Pass rate: ~57% · Five-rate: 15% · Workload: High
AP World covers everything from 1200 CE to the present across six thematic lenses. The breadth is the main challenge — there's no way to memorize everything. The exam rewards students who understand large patterns (trade networks, imperialism, revolutions) over those who try to know specific dates and events.
AP Government
Pass rate: ~58% · Five-rate: 14% · Workload: Moderate
AP Gov requires memorization of 15 required Supreme Court cases, 9 foundational documents, and the full structure of three government branches — and the ability to apply all of it analytically. The required court cases show up directly on the exam. There's no substitute for knowing them.
AP Macroeconomics
Pass rate: ~69% · Five-rate: 21% · Workload: Moderate
AP Macro has one of the higher pass rates because the concepts, while unfamiliar, are learnable without extensive prerequisite knowledge. Graph interpretation (AD-AS, money market, loanable funds market) is the core skill. Students who master those three graphs and their shifts can navigate most of the exam.
Easier AP Exams (Higher Pass Rates)
AP Psychology
Pass rate: ~67% · Five-rate: 20% · Workload: Low-Moderate
AP Psych is accessible because the content is genuinely interesting and the MC section (67% of your score) rewards broad recall more than deep analysis. The FRQ section requires applying psychological concepts to scenarios — manageable with solid unit knowledge. The exam covers 9 units; Units 1 (bio bases) and 4 (learning) tend to be highest-frequency.
AP Calculus BC
Pass rate: ~76% · Five-rate: 39% · Workload: High
AP Calc BC has the highest pass and five-rate of any AP exam — but this is almost entirely explained by who takes it. Students who self-select into BC are typically strong math students who have already mastered AB content. The exam itself is genuinely harder than AB; the high five-rate reflects the test-taking population, not an easy curve.
AP Computer Science Principles (CSP)
Pass rate: ~72% · Five-rate: ~18% · Workload: Low-Moderate
AP CSP is a broad, conceptual computer science course — more about computational thinking, digital systems, and data than actual programming. The performance task (submitted before the exam) accounts for 30% of your score. Students who complete the task thoughtfully go into the exam with a meaningful head start.
AP Computer Science A (CSA)
Pass rate: ~68% · Five-rate: ~26% · Workload: Moderate
AP CSA requires actual programming in Java. Students with prior coding experience find it significantly more manageable. The FRQ section is where students differentiate — writing clean, correct Java under time pressure requires both syntax fluency and logical thinking.
AP Human Geography
Pass rate: ~59% · Five-rate: ~13% · Workload: Low-Moderate
AP Human Geo is typically taken by 9th or 10th graders as an introductory AP course. The content (urban geography, migration, cultural patterns, political geography) is accessible, but the pass rate reflects the age and experience level of the student population. For upperclassmen with AP experience, it would likely show a higher pass rate.
AP Environmental Science
Pass rate: ~55% · Five-rate: ~10% · Workload: Moderate
AP Enviro has a surprisingly low pass rate for its reputation as an "easier" AP. The exam requires both scientific reasoning and quantitative analysis. Students who treat it as a light course often struggle; students who engage seriously with the material generally do well.

How to Use This Information
Pass rates give you a starting point, but your individual preparation matters more than the aggregate numbers. A few practical takeaways:
Don't avoid hard exams because of pass rates. AP Chemistry and AP Physics 1 have low pass rates partly because many students underestimate them. A prepared student who starts early, practices FRQs, and builds genuine conceptual understanding has a realistic shot at a 4 or 5 regardless of what 50% of test-takers score.
Use score calculators to set realistic targets. Before committing to an AP course, it helps to understand what composite score you'd need for your target grade. Tools like APScoreHub's score calculators let you model this by subject — enter projected MC and FRQ performance and see what AP score that translates to.
The easiest AP for you depends on your strengths. A student who reads voraciously and writes clearly will find AP English Language far more manageable than someone who struggles with extended writing, regardless of what the pass rate says. Know yourself before you sign up.
Frequently Asked Questions
What is the hardest AP exam overall? AP Physics 1 has the lowest pass rate of any widely taken AP exam, at around 43–48%. AP Chemistry and AP English Literature are close behind.
What is the easiest AP exam? By pass rate, AP Calculus BC and AP Computer Science Principles consistently show the highest pass rates — though BC's numbers reflect a self-selected group of strong math students.
Does taking harder AP classes look better for college admissions? Yes, to a point. Admissions officers evaluate course rigor relative to what your school offers. Taking the hardest courses available and performing well is better than taking easier courses and acing them. But overloading on hard APs at the expense of grades or wellbeing is counterproductive.
What's the best AP to take first? AP Human Geography, AP Psychology, and AP Computer Science Principles are commonly recommended as first AP experiences because the content is accessible and the exam format is manageable without extensive prior AP experience.
