Best AP Classes for Freshmen: What to Take in 9th Grade

The best AP classes for freshmen are usually AP Human Geography, AP Computer Science Principles, and — for students already ahead in math — AP Precalculus. These courses assume little prior background, reward strong reading and study habits, and give a 9th grader a manageable first taste of college-level work.

That said, the right first AP depends less on a ranking and more on your school's offerings, your math track, and how much else is on your plate. Here is how to think it through.

Should freshmen take AP classes at all?

Often yes, but one is plenty. Freshman year is when you build the habits — note-taking, spaced review, asking for help early — that carry you through harder APs in 10th through 12th grade.

A single well-chosen AP lets you learn how AP courses pace content and how the exam is structured, without risking your GPA across the board. Many schools also restrict APs for 9th graders, so check your course catalog first.

If you are unsure about the overall load, our guide on how many AP classes you should take breaks it down by grade.

What makes an AP class good for a freshman?

Look for three things:

1. Low prerequisites. The course should not assume you have taken chemistry, calculus, or a prior AP.
2. Skills you already have. Reading, memorizing vocabulary, and writing short explanations are skills most strong 8th graders bring with them.
3. A recoverable workload. You want a class where one rough week does not snowball.

The best AP classes for freshmen

AP Human Geography

AP Human Geography is the most common freshman AP for a reason. It covers population, migration, culture, political geography, agriculture, cities, and economic development — topics that connect to the news and do not require any prior coursework.

The challenge is volume: dozens of models and vocabulary terms you must apply to real-world examples. Read more in Is AP Human Geography hard?

AP Computer Science Principles

AP CSP is a survey course on how computing works: data, the internet, algorithms, programming, and the impact of technology. It does not assume coding experience, and it is broader and gentler than AP Computer Science A.

It also includes a through-course project, so it rewards students who keep a steady pace rather than cramming.

AP Precalculus

If you completed Algebra 1, Geometry, and Algebra 2 before high school, AP Precalculus may be your natural math class anyway. Taking the AP version builds a strong base for AP Calculus later. We cover the tradeoffs in Is AP Precalculus worth it?

Do not jump ahead in math just to get an AP on your transcript. A shaky foundation in algebra shows up painfully in calculus.

AP Environmental Science and AP Psychology

Both are popular with freshmen at schools that allow them. APES blends biology, chemistry, and earth science with real-world data, and it includes some math you do without heavy computation. AP Psychology is terminology-heavy but very readable.

Which AP classes should freshmen usually avoid?

Some courses are better saved for later, not because freshmen are not capable, but because they build on prior classes:

• AP Chemistry and AP Physics C assume algebra fluency and, for Physics C, calculus.
• AP Calculus AB/BC requires precalculus mastery.
• AP US History and AP English Language are reading- and writing-intensive and are typically designed for juniors.
• AP Biology is usually stronger after a first-year biology or chemistry course.

How do you choose your first AP?

Use this quick decision process:

1. List what your school actually allows for 9th graders.
2. Match to your strengths. Strong reader? Human Geography or World History. Like logic and puzzles? CSP. Advanced in math? Precalculus.
3. Check the rest of your schedule. Honors classes, sports, and activities all count toward your real workload.
4. Talk to a current student or teacher about weekly homework hours.
5. Plan the exam. AP exams are given in early-to-mid May, so think about spring commitments now.

What does a good first AP year look like?

A strong freshman AP year is one where you finish with a high grade, take the exam, and learn how you study best. Your exam score matters less in 9th grade than the habits you build, but it is still worth preparing seriously.

After the exam, you can estimate where you landed with our AP score calculator — try the AP Human Geography calculator if that was your class.

How should freshmen prepare for their first AP exam?

Start earlier than feels necessary. A freshman's first AP exam is also their first multi-hour standardized test in that format, so stamina and timing matter as much as content.

1. Review weekly from October onward, not just before unit tests.
2. Learn the exam format by winter break — how many multiple-choice questions, what the free-response tasks look like, and how much time each section gets.
3. Use official released free-response questions from AP Central and grade them against the scoring guidelines.
4. Take one full timed practice exam in April, then spend the final weeks on your weakest units.

Treat the score you earn as data. It tells you how you learn best before the stakes rise in junior year.
