Every AP Study Guide and Prep Course We Offer (2027 Prices)

An AP study guide and prep course can be bought one subject at a time, or through a plan, and the best pick depends on how many AP exams you are preparing for. On the AP hub, you can see all 42 AP subjects we cover, with their guides, prep courses, free practice tests and score tools.

The short version is simple: every AP study guide is $5, every AP prep course is $19, five AP subjects have a guide but no course, AP Monthly is $29 a month for every AP guide and 36 AP prep courses, AP Lifetime is $149 once for the same, for good, and the All-Access Bundle is $455 once for every CLEP and DSST guide and course plus every AP guide and 36 AP prep courses. Below, you will see what each option includes, how to read the full catalog, and which choice makes sense for one exam, a few exams or many.

The full AP catalog and how to read it

The table below is the full 2027 AP catalog. It covers all 42 study guides and all 37 prep courses. A few subjects stand out. AP Japanese Language and Culture has a $5 guide, a free practice test and a $19 AP Japanese prep course, but no score calculator yet. The AP Japanese course is sold on its own: it is not in AP Monthly, AP Lifetime or the All-Access Bundle yet. The six newest guides are AP Drawing, AP 2-D Art and Design, AP 3-D Art and Design, AP Music Theory, AP Research and AP Seminar, $5 each. None of them has a free practice test yet, and of the six only Music Theory has a $19 course and a score calculator.

Here is how to read the numbers. Every guide row shows the subject, the guide price, and the size of that guide in pages, key terms and practice questions. Those counts vary by subject. For example, the $5 AP Biology guide has 54 pages, 225 key terms and 59 practice questions. The AP Precalculus guide has 32 pages, 182 terms and 40 questions. The AP Psychology guide has 49 pages, 273 terms and 55 questions.

Each course row shows a flat $19 price. That is paid once per course. If you want a worked example, the AP Biology prep course is $19 and includes 10 chapters, 64 lessons, 66 quizzes and 18 interactive labs, plus a timed final practice exam and a final exam, each with a written part and a scoring guide. All AP prep courses are built for the May 2027 exam.

If you want to browse subject pages before you buy, the all study guides page is the fastest way to scan them.

What you get in a $5 AP study guide

Every $5 AP study guide follows the same format, even though the page and question counts change by subject. You get a printable PDF as an instant download. It is built from the official units and weights, heaviest-weighted unit first.

Inside each guide, you get one chapter per official unit or content area, key terms with an example for each term, practice questions with every answer explained, common exam traps flagged, a 2-page cram sheet, and 2-, 4- and 8-week study plans built from the exam weights. Each guide page also shows 10 free sample questions before you buy.

That makes the guide a good fit if you want a printable review tool and a fixed price. A few examples: the AP English Language and Composition guide has 46 pages, 173 terms and 42 questions. The AP Calculus BC guide has 45 pages, 194 terms and 54 questions. The AP United States History guide has 55 pages, 252 terms and 45 questions.

If you only need one subject, a guide is the cheapest paid option. If you want both the guide and the course for one exam, that simple sum is $24, $5 plus $19.

What you get in a $19 AP prep course

An AP study guide and prep course are different tools. The guide is a printable PDF. The course is a fuller online review product for one subject, paid once at $19.

Every $19 AP prep course includes chapters of lessons, a quiz after every lesson, interactive labs, and a timed final practice exam and a final exam, each with a written part and a scoring guide. These courses are built for the May 2027 exam. They are also included in AP Monthly and AP Lifetime. AP Monthly includes all 42 AP study guides and 36 AP prep courses. AP Lifetime includes all 42 AP study guides and 36 AP prep courses, yours for good.

If you want to see course pages before buying, start with the AP Chemistry prep course, the AP Human Geography prep course, or the AP World History: Modern prep course. Those pages show the exact subject you are buying.

Choose a course when you want lesson-by-lesson structure and checks after each lesson, not just a review packet. Choose the guide when you want something printable and lighter. Buy both for a subject if you want the lesson flow of the course plus the short review sheets and weighted study plans from the guide. Just keep the pricing split clear: guides are $5 each, courses are $19 each, and five subjects have no course: AP Drawing, 2-D Art and Design, 3-D Art and Design, Research and Seminar.

Free practice tests and score calculators

Not every AP tool on TransferCredit costs money. There are 36 free AP practice tests and 36 free AP score calculators.

Each free practice test has 25 original practice questions that follow the official outline, and each question comes with an explanation. For AP, a free account shows your score and explanations. You can try subjects like AP Biology practice, AP Art History practice, or AP Macroeconomics practice.

The score calculators are also free. On the AP score calculator hub, you enter your raw points by section and get an estimated 1 to 5 score. It is only an estimate, not an official conversion. There are 36 calculators, one for each subject with a course except AP Japanese Language and Culture, not all 42 guide subjects.

Use the calculator after a practice set when you want a quick read on where you stand. For example, you can check the AP Biology score calculator or the AP United States History score calculator. If your estimated score is lower than you want, that is when a $5 guide or $19 course starts to make sense.

AP plans, bundle prices and what each one includes

If you are taking more than one AP exam, the plans matter more than the single-item prices. The table below shows the current 2027 prices checked on the live pages on 9 Nov 2026.

AP Monthly is $29 a month. It includes all 42 AP study guides and 36 AP prep courses. AP Lifetime is $149 once. It also includes all 42 AP study guides and 36 AP prep courses, yours for good. You can see both options on the AP plans page, or go straight to AP Monthly or AP Lifetime.

The All-Access Bundle is different. It is $455 once, with a list price of $700 and the launch discount applied at checkout. It includes every CLEP and DSST prep course, 36 AP prep courses and every AP, CLEP and DSST study guide, for life. See the All-Access Bundle page if you are also comparing AP with other exam paths.

Every TransferCredit plan includes access to UPI Study's 90+ ACE & NCCRS courses for the time the plan states. Single $19 courses and $5 guides are not plans and do not include this.

How to choose the right AP option for you

Start with the number of AP subjects you actually need.

If you need one subject, keep it simple. Buy one $5 guide if you want a printable review. Buy one $19 course if you want lessons and quizzes. Buy both if you want both formats, for $24 total. A student preparing for AP Chemistry, for example, might pair the AP Chemistry study guide with the course page already linked above.

If you need several AP guides, an AP plan can cost less than buying guides one by one. AP Monthly at $29 makes sense if you want short-term access to all 42 guides and 36 AP prep courses. AP Lifetime at $149 makes sense if you want all 42 guides and 36 AP prep courses without a monthly bill. Before you choose, compare the current details on the plans and pricing page.

If you need AP plus other exam programs, only then should you look hard at All-Access. It includes AP, CLEP and DSST courses and guides together. If that sounds like your situation, this related post can help you compare paths: CLEP vs DSST vs AP.

One more thing matters more than any prep product: each college sets its own AP credit policy, including the score it needs and the credit it gives. AP scores run from 1 to 5, but credit is always the college's decision. If you are already thinking about transfer, read how to make sure AP credits actually transfer.
