AP (Advanced Placement) study guides condense each college-level exam administered by the College Board into a unit-by-unit review.[1] Each AP study guide pairs with a year-long AP course, and a strong score can earn you college credit or advanced placement at thousands of colleges. This page gathers free study guides for all 17 AP exams we cover, each organized to the official College Board course and exam description.
Almost every AP exam has two sections — a multiple-choice section and a free-response section — and on most exams each counts for about half of your score.[2] Our study guides cover the content and skills for both sections, organized by the official course units so you can focus on what carries the most weight. We group the 17 guides below by subject area so you can jump straight to your exam.

How AP Scoring Works (1–5)
Every AP exam is reported on a scaled score of 1 to 5.[4] Your multiple-choice section and free-response section are combined into a composite score, which the College Board converts to the 1–5 scale each year based on the exam’s difficulty — there is no fixed raw percentage to “pass.” The scale means:
- 5 — Extremely well qualified
- 4 — Well qualified
- 3 — Qualified (the common credit threshold)
- 2 — Possibly qualified
- 1 — No recommendation
A 3 or higher is generally considered passing and is the level many colleges require for credit — but credit policies vary widely, and selective schools often want a 4 or 5. Always check the credit policy of the college you plan to attend.[2]
How to Use These Study Guides
- Map the course first. Read through the full study guide once to see every unit and how the College Board weights it, so you know where to spend your time.
- Lead with the heaviest units. Study one unit at a time, starting with the highest-weighted content, and work the worked examples as you go.
- Pair with flashcards. Use the matching AP flashcards to lock in the terms, formulas, and dates each guide introduces, then return to the guide for the reasoning behind them.
- Test, then revisit. After each unit, take a practice test to find weak spots, then come back to the guide to close those gaps before exam day.
- Don’t neglect free response. The guides cover both sections. Practice the official free-response questions on the College Board site, since the free-response section is roughly half your score on most exams.
AP Study Guide FAQ
An AP study guide is a structured summary of everything an AP (Advanced Placement) exam tests, organized by the College Board's official course units. Each of our AP study guides walks through the key concepts, formulas, vocabulary, and skills for one exam — calculus, biology, US history, English, economics, and more — so you can review the whole course efficiently and target the units that count most toward your score.
Yes. Every AP study guide on Career Employer is completely free, with no account required. Each guide is organized to the official College Board course and exam description, so you review exactly the content and skills the real exam measures — and you can pair the guide with our matching free practice tests and flashcards for the same exam.
AP exams are scored from 1 to 5. A score of 3 is the College Board's threshold for "qualified," and many colleges grant credit or placement for a 3 or higher. Credit policies vary widely, though — selective schools often require a 4 or 5, and some departments do not award credit at all. Always check the specific credit policy of the college you plan to attend.
Almost every AP exam has two sections: a multiple-choice section and a free-response section. On most exams each section counts for about half of your score, though weighting varies (AP Environmental Science, for example, is 60% multiple choice and 40% free response). Our study guides cover the content and skills for both sections, since the free-response questions draw on the same units as the multiple-choice questions.
Start by reading through the full guide to map the course, then prioritize the highest-weighted units. Review one unit at a time, work the examples, and check your recall with the matching flashcards. After each unit, take a practice test to find weak spots, then return to the guide to close those gaps. The guide is your reference; practice tests and flashcards are how you make it stick.
The College Board offers around 40 AP courses and exams across the arts, English, history and social sciences, math and computer science, the sciences, and world languages and cultures.

Yes. Each AP study guide is organized to the College Board's current course and exam description for that subject, including the official units and their relative weighting. We update the guides as the College Board revises its courses so your review always reflects what the live exam measures.
