What's the best way to study for AP Chemistry? Practice, practice, practice. This article will provide you with links to every practice test and quiz for AP Chemistry that's available online, including full official and unofficial tests, shorter quizzes that cover each topic area, and other prep services you can access with a subscription!

Official AP Chemistry Practice Exams

Official exams are the best practice materials because they help you make accurate predictions of your performance on the real test. They will also get you used to the test format so that you're not caught off guard by the structure of the final exam.

Unfortunately, for AP Chemistry, most of the available official practice materials are for the old version of the test (pre-2013), but these can still be useful for practice. You should be able to get newer practice tests from your teacher or through review books.

I'd recommend starting with the unofficial practice materials listed later on in this article and then using official tests in the final stages of your studying. That way you'll be in the best position to estimate your ultimate AP score, and you won't squander limited resources.

Old Official Released Exams:

These official exams come from before 2013 (when significant changes were made to the AP Chemistry curriculum), so they're formatted slightly differently from the current test. They have 75 multiple-choice questions (there are now 60) and six free-response questions (there are now seven). There are also five answer choices for each multiple-choice question, whereas now there are only four.

The old AP Chemistry exam emphasized calculations and factual knowledge over a strong understanding of fundamental concepts and mastery of scientific practices. The questions on these tests will still help you practice your skills; just make sure you also use more recent materials for an accurate preview of what to expect on test day.

Current AP Chemistry Course and Exam Description (multiple choice practice included)

Go to page 216 of this course description to review sample multiple-choice and free-response questions for the current exam. This is not a full practice test (it only has 15 multiple-choice questions and two free-response questions total), but it's directly from the College Board, so it's the most accurate and up-to-date representation of the format and content of the test.

Free-Response Questions 2014-2021

These free response questions are from the most up-to-date version of the test. I would advise you to save most of them for later on in the year when you're more serious about practicing for the real AP exam. There are seven questions from each year.

Practice Tests from Your Teacher

Since there aren't any full AP Chemistry practice tests available online that reflect the current format of the exam (well, any that we can legally link to in this blog post), you can also ask your teacher for additional practice materials. AP teachers often have access to extra practice tests from the College Board that are available for classroom use.

Maybe you should have thought of that before you interrupted all of my lectures with unnecessary questions about when I'm planning on "breaking bad." I don't even watch that show, Eric. You are a nightmare.

Unofficial Free AP Chemistry Practice Exams

There are also a bunch of unofficial resources for AP Chemistry practice questions on various online learning platforms and independent sites. Few of these offer complete tests in the same format as the real exam, but they do provide a large repository of practice questions (mainly multiple-choice). These are great if you're looking for questions in specific topic areas or are studying early on in the year and want to avoid certain concepts that you haven't learned in class yet.

Just be wary of using these resources too much in your studying, and make sure you supplement them with official College Board materials at regular intervals. Unofficial practice questions often lack many of the nuances of real test questions. In a lot of cases, they will test straightforward factual recall whereas on the real test you'll have to do more complex analyses of unfamiliar experimental scenarios.

Varsity Tutors Diagnostic Tests

There are six diagnostic tests here with 50-60 questions each at varying difficulty levels. You'll also be timed as you take the tests so you can get a better sense of your pacing. Questions are multiple-choice only, so this won't give you any free-response practice. There are also tons of practice quizzes divided by topic, so you can use those to tackle tricky subject areas. We'd also recommend trying out their AP Chemistry practice app (it's free).

Albert Quizzes

This site includes quizzes for each concept broken down according to the major units of the course. This site will track your progress and tell you what percentage of questions you got right from each difficulty level (questions are organized into easy, medium, and hard categories). You can also access additional questions, including free-response, if you pay $25 to set up an account.


Here you'll find tons of review questions and activities, with lengthy practice quizzes for each unit of the course. This is one of the few resources that has non-multiple-choice questions that you can check automatically online.

Crack AP

This website offers 46 different multiple-choice practice tests (each is quite a bit shorter than the actual exam), and lots more downloadable practice questions organized by topic. You’ll be able to see whether or not you’ve answered correctly, as well as explanations of each question and answer.


This quiz includes 58 free AP Chemistry practice multiple-choice questions.


There's a lot of stuff here, but if you're just looking for practice tests, you can find them at the end of the list of resources for each unit. There are multiple-choice and free-response tests for most units with accompanying answer keys.

Unofficial Paid/Subscription AP Chemistry Practice Exams

Here are some additional resources that will cost you some money, but they might be worth it because they provide full properly-formatted AP Chemistry practice tests.

Peterson's ($39-$49 per month)

  • Two full-length practice tests (up to date format and content)
  • Answer explanations
  • Automatically tells you what you still need to study based on your results
  • Also includes test prep for other AP exams

Sterling Test Prep (price varies)

On this site, you can buy individual practice tests for each topic in AP Chemistry. All of them together cost almost $100, so that might not be feasible, but you can get each specialized practice test for about $3 each (most have around 60 questions). You can also just get the Sterling book of practice questions, which many students seem to find helpful.

Review Books (price varies)

Review books can be great resources because many of them include instructions for how to structure your studying in addition to focused content overviews. For AP Chemistry, we recommend the 5 Steps to a 5 and Crash Course books. You can click on the link in the title of this section to read my full article on the best review books for this course.

Barron’s AP Chemistry, and The Princeton Review AP Chemistry Prep book are also excellent resources. In addition, each of these includes several different practice tests you can use to help you be prepared for test day!

How to Use AP Chemistry Practice Tests

Practice tests are great study tools for AP tests, and they're especially helpful for a subject like Chemistry that involves a lot of calculations and experimental analysis. In the next couple of subsections, we'll tell you how to use practice tests throughout the school year to prepare for the AP Chemistry exam.

First Semester: Using Practice Tests for Your Class

It's not practical to take full practice tests during the first semester of AP Chemistry because you haven't covered enough of the course material yet. Focus on official free-response questions and unofficial topic-specific practice tests that address aspects of the curriculum that you've learned already. It's a great idea to start early and do consistent reviews so that your knowledge base remains strong throughout the year.

Since chemistry is a subject that builds on the fundamental concepts learned in the first few months of class, it's vital that those early lessons are solidified in your memory. This way, more complex material that you learn in the second semester won't fly over your head. You can also consider getting a prep book; most of them have practice questions organized by chapter for selective review of different concepts.

Second Semester: Preparing for the AP Test

During your second semester, you can start to take full practice tests to predict your AP score-range. At this point, you've learned most of the material that will be covered in the class, so your scores should accurately reflect your abilities. Every time you take a full practice test, keep track of the areas where you need more practice.

As we mentioned at the beginning of this article, we would recommend saving the most up-to-date official practice materials for later in the semester so that the format of the current test stays fresh in your mind. As you take each test, circle any questions where you were unsure about your answer. Even if your choice ends up being correct, you should still plan to go over these concepts, so you don't feel shaky about them on the real AP test.

After you've finished taking the test (with realistic time constraints!), categorize your mistakes by topic area, and use their distribution to inform the rest of your studying. The purpose of taking practice tests is to diagnose your weaknesses so you can address them as efficiently as possible. DON'T go from one test to the next without taking a deeper look at what went wrong! You'll end up wasting your time, and your second practice test is unlikely to demonstrate much improvement.

Spend at least a couple of hours after each practice test doing practice problems and reviewing concepts that you didn't quite understand when they came up on the test. When you feel satisfied that you have a better handle on the background information and solution methods, you can take a second practice test to see how much you've improved.

The process as a whole should work like this:

  • Take and score first practice test (4 hours)
  • Evaluate mistakes (1.5 hours)
  • Practice problems and study content to improve weak areas (2.5 hours)
  • Take and score second practice test (4 hours)
  • Reevaluate your progress and repeat steps if necessary!

One cycle through all of these steps will take around 8-10 hours, but you can repeat the steps ad infinitum until you're satisfied with your scores. If you find that you're not improving between practice tests, you'll need to reevaluate your study strategy. To master a complex subject like chemistry, you need to have a strong grasp of the fundamental concepts. Then, you can build on that understanding for more difficult problems. Be sure to do lots of practice problems where you're required to justify your answers!

Practice tests are essential study tools, especially for AP Chemistry. Doing practice problems that align with the format and content of the real exam will help you to gain familiarity with the material and feel less stressed on test day.

Try to start your studying with unofficial practice tests to build up a strong knowledge base, and then move onto official practice tests when you're ready to estimate your real AP score level.

As you take practice tests, assess your mistakes and plan out your study time according to which areas need the most work. Make sure you start with basic concepts and then work your way up to more complex problems. Use these practice materials to detect gaps in your knowledge, and fill them before you take the test!
