Advanced Placement® (AP) courses are college-level classes in a wide variety of subjects that you can take while still in high school. They’re usually taken during a student’s junior year. Each AP course ends with a standardized exam, developed and scored by the College Board® on a scale of 1 to 5. Most colleges and universities in the United States grant college placement and/or credit to students who obtain high scores (usually 3 or higher) on these exams.
What is an AP Class?
Today, students face ever-increasing pressure to perform well in school and get ahead. Providing “AP classes” is one such way that high schools across the country have begun to meet this demand. These classes are taught in parallel with the standard high school curriculum but cover more in-depth content equivalent to entry-level college courses. AP classes are a great way to jumpstart your college career. Depending on the school you're attending, an AP class can run for just one semester or for the entirety of one high school year (two semesters).
Taking an AP class will typically sharpen your writing and critical thinking skills, as well as your ability to solve problems and make connections across broad topics. For these reasons, students are strongly advised to register for an AP class if they plan to attend college, impress the college admissions committee, and save money on tuition.
How Many AP Courses Are There?
For the 2023-2024 school year, there are 38 AP courses within seven primary disciplines. The number of AP courses and classes offered varies between schools. So, please be sure to check with your school AP Coordinator or high school counselor to see which AP courses are available at your high school. The following are the seven disciplines in which you can take AP courses:

The Hardest and the Easiest AP Classes
In general, AP classes are sometimes labeled as "easy" or "hard" based on their national passing rates. However, the passing rate only considers AP scores ranging from a 3 (considered an average score) to a 5 (the highest score possible). As a result, passing rates are only a partial indicator of whether an AP class is actually “hard” or “easy.” Some AP classes may be easier to pass but require a lot of time commitment and homework, while others may be harder to pass because the content is challenging but has less homework.
The difficulty of any class is highly dependent on numerous factors. For example, students at different high schools nationwide will have varying aptitude, skills, learning habits, and intellect. Students will also have different teachers. The pace of learning, testing, and reviewing will be different in each class. So, classifying a course as part of the “easiest” or “hardest” AP classes is not always so clear.
With that being said, the percentage of students scoring a 5 on an AP exam can be correlated with whether the AP course is easy or hard. Below, we’ve listed several classes with the highest and lowest percentages of students scoring a 5 on the exam:
The “Hardest” AP Classes
As of 2022, these are the top 10 hardest AP classes, based on an approximate percentage of students scoring a 5 on respective AP class, that you could take if you’re up for a challenge!
Note: This list excludes AP Foreign Language, Arts, AP Seminar, and AP Research classes.
The “Easiest” AP Classes
These AP classes had some of the highest percentages of students scoring a 5 in 2022.
Note: This list excludes AP Foreign Language, Arts, AP Seminar, and AP Research classes.
Analyzing the percentage of students who scored a 5 is one possible way to identify the hardest AP courses (e.g., English Literature, Physics, Biology, and Chemistry). However, there are courses with a high percentage of 5 scorers but are challenging to pursue.
Let us take Environmental Science as an example; this class is considered “easy” by some metrics (students often call it easy), but it has a very low frequency of students scoring 5’s. Moreover, classes that are generally considered “difficult,” like AP Calculus BC, have a high percentage of students scoring a 5.
So, be careful about how you measure the difficulty of an AP course, as course difficulty is multifactorial and not always clear-cut. Besides, how you perceive class difficulty will be determined by your personal interests, career goals, learning ability, and the AP teacher’s impact on course rigor.
Top 10 Most Popular AP Courses
Various factors play a role in determining which AP courses are taken by the greatest number of students and why certain courses are more popular than others. However, several main reasons help to explain the popularity of an AP course.
- First, some AP courses can be broadly applied to many students’ future college credits, like AP English Language and Composition. Regardless of your specialization, many colleges require you to pass these core courses to secure the credits required to graduate. Courses like these are the top favorites among AP test-takers.
- Second, some courses can also be used to receive college credit across multiple core subjects and specializations. For example, if you plan to major in physics and pursue a career in the field of medicine, you are still required to pass foundational courses like Calculus AB and Chemistry during your first year of college. Getting a passing score in these corresponding AP courses allows you to bypass them and go for more advanced courses in your freshman year of college.
- Third, many of the more popular AP courses, such as AP Calculus AB or AP Chemistry, are offered by most high schools. This also means you are more likely to have a teacher for AP Chemistry than one for AP Chinese Language in your high school. The popularity of a particular course is greatly affected by these factors.
- Last, there’s a ‘word-of-mouth’ reputation that some AP courses can have for being more difficult than others, which might deter some students from taking them. Sometimes, students just want to secure the “easiest” credits they can before college!
Number of Test Takers in 2022 for Each AP Course
The following courses have been consistently preferred by test takers year over year. Based on the number of test takers in 2022, the list compiles the most popular AP courses:
Why Take AP Classes?
You might think to yourself, “But why should I take AP classes?” There are numerous and significant benefits that come with taking an AP course. They offer you the time and space to dig deeper into the subjects you love and gain a new appreciation for that discipline. With early access to college-level courses, you’ll harness and tone your creativity and intellect so that you are prepared for the next stage in your career. You will build your self-confidence and mastery of a subject, and you will learn essential time management and studying skills needed for college and career success. Next, we list four more advantages of taking AP classes during high school:
- College readiness
These AP courses are challenging, fast-paced, cover more subject material than your standard high school class, and even encourage you to conduct research and analysis. By exposing yourself to college-level introductory courses, you will make your transition from high school to the first year of college much easier. You’ll be able to harness and tone your creativity and intellect such that you are prepared for the next stage of your career goals and challenges.
- Boost your college applications
Scoring well on an AP exam looks good on your resume and implies that you are college-ready. Consequently, AP courses positively impact your college applications when admissions officers consider that you have challenged yourself academically.
“85% of institutions report that a student’s AP experience favorably impacts admission decisions.”Taking AP exams also indicates that you have worked hard and have acquired the skills and knowledge needed to take advanced college courses, which boosts your chances of getting admitted into the school of your choice exponentially!
- Strengthen your high school transcript
Your high school may also apply extra weight to your GPA based on AP classes and scores. Each AP class you take usually adds one point to your overall GPA. For example, suppose you and a fellow student take the same course load with one exception: only you take an AP class while the other student takes the regular version of the class. If you get an A in your AP class, your GPA will naturally be higher than the other student’s GPA. In addition, with enough AP courses under your belt, you can even make it into the top 10% of your graduating class.
- Save time and money!
By entering college with multiple AP exam credits, you can fast-track your way into courses usually taken during the second year of college. You can save time and tuition fees by skipping the introductory college courses that you took in the form of AP courses during your high school. With this, you may have the potential to skip through one year of college and save one-quarter of your overall college fees.
Research shows that students who receive a score of 3 or higher on AP Exams typically experience greater academic success in college, graduate early, and have higher graduation rates than their non-AP peers.
Can I Take an AP Exam Without Taking the Class?
Yes! It is not mandatory to take an AP class if you want to take the AP exam, even though AP classes do come with many benefits. You can self-study at home and use resources to prepare for the exam. However, it is always advised to seek expert guidance from course instructors to help you prep as these courses are quite content-heavy and expand beyond your standard high school curriculum. This is where the importance of online AP courses comes in! Some students prefer to prepare for their AP exams from the safety and comfort of their homes, so it will be up to you to decide what works best.
When Should I Start Taking AP Classes?
Generally, it is recommended to take AP classes in 11th grade because many AP classes have rigorous college-level curricula. Ideally, you should sign-up for your AP classes after you’ve developed the foundational knowledge needed for tackling AP-level course content. In rare situations, however, students in 9th and 10th grade opt to take one or two AP classes, which is acceptable to the College Board.
How Many AP Classes Should I Take?
It depends. In general, most AP core courses, like Math or English, are taken by students to bypass entry-level college courses. Each institution has its own AP credit policy, so the college credits you get for taking AP courses vary. However, a minimum AP score of 3 is required for you to be eligible for college credit and/or placement. If you're wondering how many AP courses are required for college, students typically take three AP courses per year.
Although there is no “magic number” of AP courses that guarantee your success in college, below is some information that can help:
- Ivy League universities like Princeton and Harvard seek absolute excellence and uniqueness from their candidates. So it is safer to have taken and scored exceptionally well in 8 to 12 AP courses. Try for a mix of core subjects like English, History, Math, and Science. You should also focus on taking specialized courses, such as Physics C, that may pique your interest.
- Most highly selective colleges (Top 20) look for students who have taken AP courses in many core subjects. They also expect you to take additional AP courses related to your future goals, specialization, or career interests. In all, this mix of AP courses can range from 6 to 10 courses. If you’re planning to apply to universities like Stanford or MIT, it is recommended that you start taking 3 to 4 AP classes per year. By the time you graduate high school, you’ll have enough AP classes to gain admittance into these prestigious universities if you score well on the AP exams.
- Selective colleges (Top 100) want students who have taken AP courses in most core subjects, plus one or two additional subjects. That amounts to around 4 to 6 courses, which is doable if you take 2 to 3 courses each during your 11th and 12th grades.
- Less selective colleges expect their incoming students to take AP courses in some core subjects or subjects related to their chosen college major. The number is somewhere between 1 to 5 courses.
Let’s try and break it down in the following table:
|How many AP Classes are required for certain colleges?|
|Ivy League Colleges||Minimum of 8 AP courses (5 core + 3 specialized)|
|Top 20 schools||Minimum of 6 AP courses (core + specialized)|
|Top 100 schools||Minimum of 4 AP courses|
|All other schools||Minimum of 1 AP course|
Choosing the Right AP Course
Even though there are 38 AP Courses offered by the College Board, you should always choose an AP course based on yourspecific passions and strengths so that you can do well. Here are some pointers to help you out:
- Choose a combination of core and specialty courses to keep things balanced for your college degree. Some AP courses are easy to justify taking because they have a broad application and leave room for flexibility later! For instance, language-based AP courses like English and Math courses like Calculus AB are usually top picks if you’re not sure about your specialization or major in college.
- You must remember to consider which subjects will earn you college credit and/or placement. If the AP exam you’re interested in is not accepted at your prospective college, that removes a significant benefit of taking the AP course. You should begin by identifying the institutions that offer credits for the AP classes you wish to take. Start by looking through AP Credit Policy Search on the College Board website that lists the institutions with the corresponding AP courses that they offer credit for.
- Pick courses that help your college degree. If you already know what field you’re going to major in, choose those AP courses related to that subject. For instance, selecting courses like AP Calculus BC and AP Physics 1 for Math oriented fields like Engineering, Astrophysics, or allied disciplines, can boost your career goals. Moreover, students interested in pursuing careers in the areas of Medicine and Pharmacy usually go for courses like AP Biology and AP Chemistry to prepare themselves for more advanced courses in their first year.
In any case, it is critical to review the topics and curriculum of the AP courses that you are interested in taking. Speak with your AP teachers, your peers, and seniors to learn about the course content and AP practice tests. By doing so, you will get a preview of these courses, which will help you decide on which AP courses you want to enroll in.
