Most Popular AP Classes: Latest Enrollment Data and What It Means (2026)

The most popular AP exam in College Board's latest complete subject-level dataset is AP English Language and Composition, followed by AP United States History. English Literature, World History: Modern, and U.S. Government and Politics also draw very large numbers of test takers.

Popularity can tell you that a course is broadly available or commonly placed in a school's core sequence. It cannot tell you whether that AP is easy, ideal for your goals, well taught at your school, or favored by every college.

Latest official AP popularity ranking

As of July 2026, the latest complete subject table is College Board's 2025 AP score-distribution report. It covers May 2025 exams and states that 6,182,171 AP exams were taken by 3,243,979 students from 23,664 secondary schools.

The top ten individual exams by number of test takers were:

Rank	AP exam	2025 test takers
1	English Language and Composition	616,294
2	United States History	516,738
3	English Literature and Composition	416,531
4	World History: Modern	411,547
5	U.S. Government and Politics	387,973
6	Psychology	334,038
7	Biology	287,232
8	Calculus AB	285,891
9	Human Geography	282,781
10	Statistics	266,791

AP Precalculus was close behind with 253,596 test takers. These are exam-participation counts, not a count of every student enrolled in an AP-labeled class. Some enrolled students do not test, and some independent students test without taking the course.

Why English Language and APUSH are so large

English Language and U.S. History often appear in the junior-year core curriculum at U.S. high schools. A school can offer an advanced version of a course many students already need, which creates more potential enrollment than a specialized elective.

By contrast, AP Physics C: Electricity and Magnetism had 29,708 test takers in the same dataset. That does not make it less valuable. It usually sits later in a narrower math and physics sequence and therefore has a smaller eligible population.

Popularity often reflects four structural forces:

• how many schools offer the course;
• whether it satisfies or parallels a graduation subject;
• which grade levels can reasonably take it;
• how many prerequisites stand before it.

Popularity is not difficulty

The number of test takers does not measure the intellectual demand of a course. A widely available course may be challenging because of reading volume, writing, content breadth, quantitative work, or pace. A small course may simply require uncommon prerequisites.

Pass rates do not create a clean difficulty ranking either. The students selecting Calculus BC are not the same population selecting Human Geography. Differences in prior preparation, access, teacher support, and self-selection affect score distributions.

Use our AP difficulty guide to compare workload and prerequisites without treating score data as a universal ranking.

Popularity is not an admissions bonus

A course does not become more impressive because more students take it, nor does rarity automatically make a course more impressive. Admissions readers can consider what your school offered, the sequence you followed, how you performed, and whether the schedule remained balanced.

For example, AP Calculus BC may be a sensible choice for a student who completed precalculus and wants further quantitative preparation. It is not a sensible jump for a student missing algebra and trigonometry foundations merely because fewer students take BC than English Language.

Similarly, AP English Language can be valuable even though it is the largest exam. Its analysis and argument skills can support nearly every academic field.

Our guide to APs in college admissions explains how course context matters more than a popularity position.

Popularity is not course quality at your school

The same AP title can involve different calendars, assignments, class sizes, support, and teacher experience. College Board defines the framework and exam, but your day-to-day learning depends on the local course.

Before registering, ask for:

• prerequisites and placement guidance;
• a current syllabus;
• typical weekly reading or problem-set time;
• major laboratory, essay, or portfolio requirements;
• available help and teacher office hours;
• whether the course is offered every year.

A smaller AP with strong instruction can be more useful than a popular course scheduled at the wrong point in your sequence.

What the list reveals by subject area

English and history dominate the top five

English Language, U.S. History, English Literature, World History, and U.S. Government occupy the first five positions. These subjects fit broad school requirements and can be offered to large grade-level cohorts.

Psychology has broad elective appeal

AP Psychology ranks sixth. It often attracts students from many intended fields because it connects biological, behavioral, cognitive, and social questions. Its popularity does not mean every school's workload or prerequisite expectations are identical.

Biology and Calculus AB anchor common STEM sequences

AP Biology and Calculus AB sit close together in the dataset. Both can serve large groups of STEM-oriented students, but they require different foundations and work styles. Biology emphasizes concepts, experiments, data, and scientific arguments; calculus emphasizes functions, change, accumulation, modeling, and reasoning.

Human Geography reaches many earlier high-school students

Some schools offer Human Geography in ninth or tenth grade, expanding the eligible population. It introduces spatial analysis, population, culture, political organization, agriculture, cities, and economic development.

Statistics crosses academic fields

Statistics supports science, social science, business, public health, psychology, and data-informed research. Its broad applicability helps explain its high participation, but course selection should still follow local math sequencing.

How to use popularity data responsibly

Treat the list as a starting point for questions:

1. Why is this course common at my school?
2. Does it continue a subject sequence I need?
3. Are the prerequisites compatible with my record?
4. Does the course teach skills I want?
5. What does it cost in weekly time?
6. Which course would it replace?

Do not use “everyone takes it” as the only reason to enroll. Also do not reject a course merely because it is common; widely taken core courses can provide excellent preparation.

A course-choice example

Suppose a junior is choosing between AP Psychology and AP Chemistry. Psychology is more popular nationally in the 2025 dataset, but the student is completing honors chemistry, considering materials science, and has room for a lab-heavy course. AP Chemistry may be the stronger next step.

Another student is interested in neuroscience, has a packed schedule, and lacks chemistry prerequisites. Psychology may be more appropriate. The national ranking supplies context, not the answer.

Add workload before deciding how many APs

Popularity lists make it easy to collect course names without calculating their combined demands. Build a weekly calendar containing classes, homework, labs, activities, work, commuting, meals, and sleep. Use actual local estimates rather than national stereotypes.

The AP course-load guide helps turn those estimates into a sustainable total.

Check the data year and definition

When another article calls an AP “most popular,” verify:

• the administration year;
• whether the number refers to test takers, exams, enrollment, or schools;
• whether language totals include all test takers or a standard group;
• whether an AB subscore has been incorrectly counted as a separate exam;
• whether new courses have had time to expand.

College Board publishes updated data through its AP data and research page. Rankings can change after a new administration, so keep the year beside every number.

Bottom line

AP English Language was the largest May 2025 exam, and English and history courses dominate the upper part of the participation list. That tells you about scale and access. It does not identify the best course for an individual student.

Choose APs from prerequisites, school context, educational goals, instructor information, and workload. Popularity is useful background only when its definition and limits stay visible.
