Choosing the right AP exams can make or break your junior and senior year. Some AP exams have pass rates above 80%, while others see nearly half of all test-takers fail. The difference often comes down to who takes the exam, not just how hard the content is. Below, we rank all 35 AP exams that use standard multiple choice and free response scoring, using College Board score distribution data so you can make an informed decision about which AP courses to take.

Easiest AP Exams (Highest Pass Rates)

The following table ranks all 35 AP exams by the percentage of students who score a 3 or higher (the "pass rate"). A higher pass rate generally means more students find the exam manageable, though self-selection bias can inflate these numbers for certain exams.

32 AP European History 62% 14%
33 AP Music Theory 61% 19%
34 AP Statistics 60% 17%
35 AP Latin 59% 12%

A few things stand out immediately. AP Spanish Language sits at the top with an 85% pass rate, but a large share of its test-takers are native or heritage Spanish speakers, which inflates the numbers. AP Calculus BC ranks second at 79% with an impressive 44% five-rate, but students who take Calc BC are almost always strong math students who already passed Calc AB. AP Chemistry jumped to third place (78%) in the 2025 data. Meanwhile, AP Statistics (60%) and AP Music Theory (61%) sit at the bottom, with AP Calculus AB (64%) and AP World History (64%) close behind.

Hardest AP Exams to Score a 5

If your goal is a top score, the 5-rate matters more than the pass rate. Some exams pass a majority of students but make it extremely difficult to earn the highest mark. Here are the 10 hardest AP exams to score a 5 on:

Rank Exam Score of 5 Rate Pass Rate (3+)
1 AP Environmental Science 13% 70%
2 AP English Language 13% 74%
3 AP World History 14% 64%
4 AP French Language 14% 74%
5 AP US History 14% 73%
6 AP Psychology 14% 70%
7 AP Art History 16% 65%
8 AP English Literature 16% 74%
9 AP Statistics 17% 60%
10 AP Human Geography 17% 65%

AP Environmental Science tops this list — while its pass rate improved to 70% in 2025, only 13% of students score a 5. AP English Language has a high pass rate (74%) but only 13% earn top marks. Several other exams with solid pass rates, like AP US History (73% pass but only 14% fives) and AP Psychology (70% pass but only 14% fives), are actually quite hard to master at the highest level.

What Makes an AP Exam Easy or Hard?

AP exam difficulty depends on four key factors: who takes the test, how the content is structured, how generous the curve is, and the exam format itself.

Self-selection bias is the biggest reason pass rates vary so much between exams. AP Spanish Language has an 85% pass rate not because the exam is simple, but because many test-takers are native speakers. AP Calculus BC has the highest 5-rate (44%) because the students who take it are almost exclusively high-achieving math students who already completed Calculus AB. Conversely, AP Statistics and AP Music Theory have lower pass rates partly because they attract broad student populations, including many who are less prepared for the rigor of the exam.

Subject difficulty matters too. Physics and chemistry require strong mathematical reasoning and problem-solving skills that many students find inherently challenging. History and English exams require extensive writing under time pressure, which is a different kind of difficulty. Economics and psychology exams are more straightforward in format — mostly multiple choice — which tends to make them more predictable.

Curve generosity varies between exams. College Board adjusts the composite-to-score mapping each year, and some exams consistently have more generous curves than others. An exam where you can miss 30% of the points and still get a 5 is more forgiving than one that demands near-perfection.

Exam format also plays a role. Exams that are 100% multiple choice (like AP Psychology) tend to have higher pass rates than exams with lengthy free response sections that require sustained writing or complex problem-solving. The more subjective the grading, the more room there is for students to lose points on technicalities.

Easiest AP Exams to Self Study

If you want to take an AP exam without enrolling in the class, these six exams are the most feasible to self study. They have content that can be learned from a prep book, do not require lab work, and have relatively straightforward exam formats.

  • AP Psychology — The content is mostly vocabulary and concept-based, making it ideal for self study with a good prep book. The exam is entirely multiple choice (Section 1) and short free response (Section 2), with no essays. Many students self study AP Psych in a few months and score a 4 or 5.
  • AP Human Geography — The material covers population, migration, culture, agriculture, urbanization, and political geography. It is conceptual rather than technical, and a prep book combined with practice tests is usually sufficient preparation. The FRQ section requires short written responses but no long essays.
  • AP Environmental Science — APES covers a broad range of environmental topics at an introductory level. The content is accessible, though only 13% of students score a 5. The challenge is breadth — you need to cover a lot of ground. A comprehensive prep book and practice exams can get you there without a classroom.
  • AP Macroeconomics and AP Microeconomics — Both economics exams are relatively short in content scope compared to other AP exams. The concepts — supply and demand, market structures, fiscal and monetary policy — are logical and build on each other. Many students self study one or both in a single semester and score well.
  • AP Computer Science A — If you have any programming experience or enjoy logical thinking, AP CSA is very self-studyable. The exam tests Java fundamentals — loops, arrays, classes, recursion, and basic algorithms. Free online resources like CodingBat and the AP CSA course on Khan Academy make this one of the most accessible exams to prepare for independently.

Exams that are difficult to self study include AP Physics C (requires strong calculus skills and lab intuition), AP Chemistry (complex problem sets and lab-based questions), and the AP English exams (writing skills are hard to develop without teacher feedback).

Frequently Asked Questions

What is the easiest AP exam?

Based on pass rates, AP Spanish Language is the easiest AP exam, with 85% of students scoring a 3 or higher. However, this is heavily influenced by self-selection — many test-takers are native or heritage speakers. Among exams taken by a broader student population, AP English Language, AP English Literature, and AP French Language have pass rates of 74%, and AP US History has a 73% pass rate. AP Calculus BC has the highest 5-rate at 44%, but it is taken almost exclusively by advanced math students. The "easiest" exam for you depends on your strengths — a strong writer may breeze through AP English Lang, while a strong math student may find AP Statistics or AP Calculus AB more manageable.

What is the hardest AP exam?

AP Statistics is the hardest AP exam by pass rate (60%), followed closely by AP Music Theory (61%). AP Environmental Science and AP English Language are tied for the lowest 5-rate at just 13%, making them the hardest exams to ace. That said, difficulty is subjective — a student who loves math may find AP Calculus AB (64% pass) easier than AP English Literature (74% pass), even though the pass rate is lower. The free response format, self-selection of test-takers, and curve generosity all factor in.

How many AP exams should I take?

Most students do well with 3 to 5 AP exams spread across their high school career. The ideal number depends on your academic goals, the strength of your course offerings, and how much time you can commit to studying. Selective colleges want to see that you challenged yourself, but they also value strong grades — a B in an AP class is not necessarily better than an A in an honors class. Start with one or two AP exams in sophomore or junior year, see how you handle the workload, and adjust from there. Quality matters more than quantity: a 5 on three exams makes a stronger impression than a 3 on seven exams.

What are the easiest AP exams to self study?

The easiest AP exams to self study are AP Psychology, AP Human Geography, AP Environmental Science, AP Macroeconomics, AP Microeconomics, and AP Computer Science A. These exams have content that can be learned independently from a prep book, do not require laboratory experience, and have relatively straightforward exam formats. Many students successfully self study these exams in 2 to 4 months and score a 3 or higher.
