What's the Format of the 2022 AP® Calculus AB Examination?

The first affair you need to know about the AP® Calculus AB exam is the format. How many questions does the test accept and how long will it have? The AP® Calculus AB exam has a full of 51 questions over a testing flow of iii hours and 15 minutes. It is broken into sections, each with calculator and non-estimator parts.

	Part I	Office I	Part II	Part II
	Part A	Office B	Function A	Part B
Number of Questions	30	15	2	four
Amount of Time	threescore minutes	45 minutes	thirty minutes	60 minutes
Reckoner Immune?	No Calculator	Calculator Required	Calculator Required	No Calculator
Score Percentage	33.3%	16.7%	16.vii%	33.3%

Section 1: Multiple Choice

Section 1 of the AP® Calculus AB exam consists of 45 multiple option questions split into a non-figurer portion (Part A) and a portion where a graphing calculator may be required (Role B). Each question has four possible answer choices (A, B, C, or D). Questions volition include algebraic, exponential, logarithmic, trigonometric, and full general types of functions, as well as analytical, graphical, tabular, and verbal types of representations. This section is one hour and 45 minutes long and counts for 50% of your final score.

In Section 1, Mathematical Practices 1, 2, and three are assessed with the following exam weights, which indicates the types of questions you may meet in this section:

Mathematical Practise	Description	Key Words	Percentage
Practice 1: Implementing Mathematical Processes	Determine expressions and values using mathematical procedures and rules.	calculate, evaluate, discover, determine, solve	53-66%
Practice ii: Connecting Representations	Interpret mathematical information from a single representation or across multiple representations.	place, indicate, interpret, represent	xviii-28%
Practise 3: Justification	Justify reasoning and solutions.	justify, explain, verify	11-xviii%

You lot will have threescore minutes to answer the 30 questions in Part A. This gives y'all almost 2 minutes per question. Since this is the non-computer section, make employ of this fourth dimension to double-check your answers. This portion is worth 33.3% of your last score.

Part B consists of 15 questions, for which you volition have 45 minutes. This averages to 3 minutes per question. This portion is worth 16.7% of your terminal score.

Department 2: Costless Response

Section ii of the AP® Calculus AB test has 6 gratis response questions. The get-go 2 questions make up Part A, during which a reckoner may be required. The remaining 4 questions are to be completed in Function B and without a calculator. This portion of the test will include various types of functions and office representations and a roughly equal mix of procedural and conceptual tasks. At to the lowest degree two questions will contain a real-globe context or scenario. This section is one hour and xxx minutes long and counts for l% of your final score.

All four mathematical practices will be assessed with the following weights:

Mathematical Exercise	Description	Key Words	Percentage
Practice ane: Implementing Mathematical Processes	Determine expressions and values using mathematical procedures and rules.	summate, evaluate, find, make up one's mind, solve	37-55%
Practice two: Connecting Representations	Interpret mathematical data from a single representation or beyond multiple representations.	place, bespeak, interpret, represent	nine-16%
Practice 3: Justification	Justify reasoning and solutions.	justify, explain, verify	37-55%
Practice four: Communication and Notation	Apply correct notation, language, and mathematical conventions to communicate results or solutions.	write, determine, stand for, notate	13-24%

You will accept 30 minutes in Part A to answer two questions, and 60 minutes in Part B to answer four questions. On average, this volition give yous about 15 infinitesimal per question. Withal, this will largely vary based on the questions you see since these questions frequently have multiple parts. It may exist wiser to skip a question and return to it later than to spend a lot of time upfront if you get stuck on it. You are permitted to return to Function A during the time allotted for Role B. All the same, you are not permitted to access your calculator during this fourth dimension.

What Topics Are Covered on the AP® Calculus AB Exam?

Basically, annihilation covered in the AP® Calculus AB course is fair game for the AP® exam. However, some topics have a higher chance of showing up on your examination than others. Here is a list of the topics that may testify up on your exam with their weights:

Unit	Topics	Resources
Unit 1: Limits and Continuity (10-12%)	evaluate or estimate limits presented graphically, numerically, analytically, or verbally establish the practice of explicitly verifying that a theorem's hypotheses are satisfied before applying the theorem define continuity of a function at a signal and over a domain determine asymptotes and limits at infinity utilize the Squeeze Theorem and the Intermediate Value Theorem	Practice on Albert: Limits and Continuity External Resource: Continuity Squeeze Theorem Intermediate Value Theorem Asymptotes

Although each unit is weighted fairly equally, if you are tight on time, you lot can focus more than on Units 5: Analytic Applications of Differentiation and Unit of measurement 6: Integration and Accumulation of Alter. Unit 7: Differential Equations is weighted the lowest, and so if you take to skip a unit, this would be the one to cut.

Another way to remember about the content covered in the AP® Calculus AB exam is through its three big ideas. These ideas are the foundation of the course and connect the units.

Big Idea 1: Change (CHA)

• Generalize knowledge about motion to various problems involving modify
• Make up one's mind rates of change at an instant past applying limits and derivatives
• Solve real-world bug involving rates of change
• Solve problems involving the aggregating of alter over an interval

What Do AP® Calculus AB Exam Questions Look Like?

Here are some released questions from the 2014 AP® Calculus AB Exam . Looking at released questions or do exams is a good way to go a feel for the examination and to test your knowledge. Note that the AP® exams and courses have undergone some changes in the last several years, so the formatting of older tests may be different. Let's expect at some instance questions from each section of the test.

Section i, Part A (No Reckoner)

1. Determining Limits (Question #two)

Source: 2014 AP® Calculus AB Exam

Questions that ask y'all to calculate or evaluate, such as this one, demonstrate Mathematical Practice 1: Implementing Mathematical Processes. This question is specifically looking for you to evaluate the limit every bit the function approaches infinity. These polynomials will require some algebraic manipulation . Begin by factoring the largest power of ten from the numerator and denominator.

\lim\limits_{ten\to\infty}\dfrac{\sqrt{9x^4+1}}{x^two-3x+5} = \lim\limits_{x\to\infty}\dfrac{\sqrt{10^4(9+\dfrac{one}{x^four})}}{x^2(ane-\dfrac{3}{x}+\dfrac{5}{10^2})} = \lim\limits_{x\to\infty}\dfrac{\sqrt{nine+\dfrac{1}{x^four}}}{1-\dfrac{3}{x}+\dfrac{5}{10^2}}

At present we know that if x is in the denominator, as 10 approaches infinity, the part approaches null. Then:

\lim\limits_{x\to\infty}\dfrac{\sqrt{nine+\dfrac{1}{10^4}}}{1-\dfrac{3}{10}+\dfrac{5}{x^2}}=\dfrac{\sqrt{9+0}}{1-0+0}.

Simplify to get the right answer, B .

2. Continuity (Question #3)

Source: 2014 AP® Calculus AB Exam

This question comes with a graph, describes tangents, and asks about the function. This is an example of Mathematical Practice 2: Connecting Representations. This question is asking for points where the function is continuous. There is an obvious discontinuity at x=0, then we tin immediately eliminate B and D from our answer options. The other piece of this question is where the function is not differentiable . The problem tells us of a vertical tangent line at x=2and there is a cusp at 10=1, so the correct answer must exist C .

Section i, Function B (Estimator Required)

one. Graphs of Derivatives (Question #11)

Section ane Part B Question one.one

Section ane Part B Question 1.2

Section ane Function B Question 1.3

Source: 2014 AP® Calculus AB Test

The given graph is the derivative of the function. Call up that the derivative function describes the slope of the original function . Y'all could hands pick a few points to compare the tangents to meet if the slope matches the y value of the derivative. Some other easy arroyo is to look for points of inflection at the zeros. We are looking at x=1, x=3, and 10=5. Specifically, the original function should switch from decreasing to increasing at x=1, and from increasing to decreasing at x=five. The original graph is increasing on both sides of x=3. The but graph that matches this description is A .

Notice that although this question comes from Part B of Section 1, nosotros did not need to use the calculator. The questions in this section may require the use of a computer, but not necessarily.

2. Definite Integrals (Question #15)

Source: 2014 AP® Calculus AB Exam

This is a problem that a calculator makes really easy. Nosotros are given the derivative function of the pinnacle of water over time, which tells u.s. the rate at which the h2o is rising. Since we already know that the h2o is 0.75 anxiety high at one hour, we just need to know how much the height of the h2o increased from i hour to two hours. Use your graphing calculator to summate \int_{1}^two 4t^3e^{-1.5t}\,dt. The height of the h2o increased one.361 anxiety during the second hour, simply don't exist tricked into picking A. The question is request for the total height of the water at 2 hours, then nosotros need to add the 0.75 foot that the h2o had already risen after the first hour. The right answer is D . Test writers similar to include answer options that yous may come across on your way to the final reply, so brand sure you identify what the question is actually looking for.

Department two, Function A (Computer Required)

1. Free Response (Question #1)

Source: 2014 AP® Calculus AB Exam

(a) Nosotros need to derive the charge per unit of alter for the volume of h2o from the volume formula

V=\dfrac{1}{3}\pi h^3. We find that \dfrac{dV}{dt}=\pi h^2\dfrac{dh}{dt}.

To evaluate at time t=0, nosotros need to know the peak of the water and the rate of change of the top. Simple plug-and-chug tells u.s. that h'(0)=-four, and we are given h=25. Plug these values into our equation and we get

\dfrac{dV}{dt}=\pi(25)^ii(-four)=-2500\pi\approx-7853.982.

Don't forget that the question specifically asked for the units of measure. Your final answer is -7853.981 cubic meters per hour.

(b) Nosotros demand to determine the minimum . The fastest way to do this is to utilize our graphing calculators. h'(t) into Y1 and use the CALC feature to observe the zero at t=6.261256. This tells united states of america when the minimum height occurs, just we however need to find the actual height of the water at that fourth dimension. For that, we'll demand to know how much the peak changed over the time period.

Evaluate \int_0^{6.261256} 2-\dfrac{24e^{-0.025t}}{t+iv}=-viii.661268408.

Call up that the top of the water at t=0 was 25, and then the height of the water at t=6.261256 is 25-8.661268408, or 16.339 meters.

(c) First step is to figure out the equation of the tangent line at t=sixteen. Evaluate h'(16)=1.195615945. We will besides need to evaluate h(16). This has a few more steps considering we first need to discover \int_0^{sixteen} h'(t)\,dt and add information technology to the starting height of 25 meters to determine that

h(16)=25+\int_0^{xvi} h'(t)\,dt=25+\int_0^{sixteen} 2-\dfrac{24e^{-0.025t}}{t+iv}\,dt=25+-1.503929129=23.4960709.

These values determine that the equation for our tangent line is y=i.195615945(t-16)+23.4960709. Remember, the question is asking to utilize tangent line approximation to find the time at which the height returns to 25 meters, and so nosotros're not quite done nonetheless. We can substitute 25 for y and solve25=1.195615945(t-16)+23.4960709to find that the h2o returns to 25 meters high after 17.258 hours , or when t=17.258.

That's a lot of work for one question, even with the use of our calculator! Remember to bear witness your work, including what you plug into the calculator, and use articulate labels and units of measurement. Each part of the question is worth multiple points and then be sure to reply every role fully.

Also, although the concluding answer can typically be rounded to three decimal places, be careful not to round earlier in the procedure. Rounding or truncating numbers in the middle of your calculations can result in an incorrect reply. The storage function on your graphing calculator can help keep rails of these longer numbers.

Section two, Office B (No Calculator)

1. Free Response (Question #2)

Source: 2014 AP® Calculus AB Exam

(a) To notice the relative maximum , we are looking for where the function g changes from increasing to decreasing. Nosotros know that g'=f, so we are looking for where the derivative changes from positive to negative. The only place that this happens is at ten=-2.

(b) When the graph of a function is concave up , the second derivative must be positive. Thus we are looking for where on the commencement derivative graph the slope is positive. This increasing behavior occurs between -one< 10<1 and ii< x<3.

(c) Let's work this problem in pieces. First notice that g is continuous at x=0, so \lim\limits_{x\to0}g(x)=g(0). To evaluate g(0), we tin can apply the givenk(3)=7and subtract \int_0^3f(10)\,dx. \int_0^3f(ten)\,dx encapsulates regions C, and D, which we know to have areas of five and iii respectively.

And then one thousand(0)=7-(5+3)=-1. Utilise this to the numerator of our limit, and we have \lim\limits_{x\to0} m(x)+1=0.

The denominator is pretty straight frontward. \lim\limits_{x\to0} 2x=0.

Hmm, our limit is \dfrac{0}{0}; in other words, indeterminate. We need to use L'Infirmary's Rule .

Instead of evaluating \lim\limits_{x\to0} \dfrac{g(x)+1}{2x}, we need to evaluate \lim\limits_{x\to0} \dfrac{g'(x)}{ii}. This is relatively easy because m'(x)=f(x).

Looking at the graph of f, we see that f(0)=0, so \lim\limits_{ten\to0} \dfrac{f(x)}{2}=0.

(d) Last part! Start past substituting in our part and simplifying using integration rules. \int_{-2}^1 h(10)\,dx=\int_{-ii}^1(3f(2x+i)+iv)\,dx=3\int_{-2}^ane f(2x+i)\,dx+\int_{-two}^14\,dx.

Apply u exchange where u=2x+one. And so du=2dx. Think to observe the limits in terms of u.

We become 3\int_{-two}^one f(2x+i)\,dx+\int_{-ii}^14\,dx=\dfrac{iii}{ii}\int_{-three}^three f(u)\,du +\int_{-2}^14\,dx.

We will need the areas of all the regions to get \int_{-iii}^3 f(u)\,du.

Substitute and simplify to go our final answer: \dfrac{iii}{two}\int_{-iii}^3 f(u)\,du +\int_{-two}^14\,dx=\dfrac{3}{2}(five-4+five+3)+12=25.5.

How to Study for AP® Calculus AB: v Steps

Now that y'all know what the AP® Calculus AB examination is going to look like, it's time to set about studying for it. Whether the exam is three months or three weeks away, the basics of how to report are the same.

1. Assess yourself

Take a do AP® Calculus AB exam. Mimic the testing environment every bit best every bit y'all can. This ways finding a serenity place for yous to focus without distractions. Set a timer for yourself to keep an eye on your pacing. You do not have to have a full length exam, simply if you have time it's a good idea to train yourself for it. If you are but doing one or two parts, adjust your timer accordingly.

2. Reflect on your areas of force and weakness

Maybe you lot realized what topics you need to review just past working through the practise exam. If not, pull up the answer key and grade yourself. Every bit you identify wrong answers, analyze why you got information technology wrong. If the exam is still a few months away, you might choose to review all of the topics. If the examination is closer, prioritize which topics you desire to focus on showtime, and which can exist skipped if time permits.

iii. Relearn the content

This isn't just a matter of reviewing some notes. Fifty-fifty if you lot retrieve parts, commit to learning the topic fully. A good way to know if you take learned a concept well is to find a partner and teach it to them. If this is an area of weakness for your partner, great! You will be able to help them study and reply their questions. Maybe they will render the favor on a different topic. If this is an area of strength for your partner, they can correct or clarify how you remember about this concept.

4. Drill. Pull out those practice questions – they don't have to exist AP® examination questions withal

Practice working problems in the topic that you just relearned, and SHOW YOUR WORK! If yous go something wrong, don't just scratch out your piece of work and get-go over. Become through your steps and identify where you lot went wrong. This is the primal opportunity to take hold of patterns of mistakes and correct them. Assuming wrong answers mean yous don't know the concept is a large studying mistake. You may understand the calculus concept but be making mistakes in the algebraic work or notation. Repetition is crucial here and have every error as a chance to acquire.

5. Repeat!

It's time to see the fruits of your labor. Take another practice exam and see if yous improved in the area you focused on. Take time to reverberate on whether you need to spend more time on this topic, or if you're ready to move on. You may already have your next topic picked out from the first do exam you took, or you can reassess to see what to piece of work on next.

AP® Calculus AB Review: 13 Must Know Study Tips

1. Make a calendar

Figure out how long you have to prepare for the AP® Calculus AB exam, then schedule when you will report and for how long. Although you may need to arrange as you go, scheduling regular written report time will help minimize in-the-moment controlling that often leads to procrastination. Attempt to exercise a little every day, even if information technology'southward but i question.

2. Mimic your testing environs

Gather the materials you need to study and ready your study area. Minimize whatsoever distractions and interruptions to your written report time. Not only will this brand your studying efficient, simply it can also make your studying more effective. The principle of encoding specificity says that as yous larn, your encephalon too encodes the surroundings in which you acquire it in. This ways that yous are more likely to be able to recall that data in like environments.

3. Build upwardly your manus muscles

A lot of exams are still administered on paper, which means yous could spend iii hours and xv minutes writing. Even being in school, you probably aren't used to writing constantly for that long. In addition to working practice issues, y'all might consider journaling or something that has yous writing for longer periods of time. During the test you can avoid losing valuable time to stretching your cramped paw muscles.

iv. Practise using your reckoner

This is a tool that you lot will have for Office B of Section 1 and Function A of Section 2. Although not every question in these sections may crave a calculator, using a figurer tin can help you answer questions quicker. It is worth learning the many functions your calculator has and get comfy using them to solve issues.

5. Learn the language of the exam

Not reading the question carefully or agreement what it is asking is a mutual mistake for test takers. Completing exercise problems can help with this, or you can review this list of chore verbs that define what type of response the AP® test is expecting.

vi. Break down the free response questions

Read the data and question parts carefully. Underline fundamental information and equations that you lot will need to bound back to. This will reduce the amount of time you spend rereading the problem and tin help you carve up pertinent information from distractors. You lot can also utilize underlining to highlight what the question is request so that you are sure to answer it fully.

7. Pay attending to details

AP® Calculus AB test takers often lose points for forgotten units of measure out or the constant C on integrals. Another mutual mistake is with rounding numbers. While your final answer for gratuitous response questions can be rounded to 3 decimal places, rounding before tin can cause inaccuracies that throw off your last answer.

viii. Double check your answers

Utilise the Primal Theorem of Calculus to reverse your solving process. Y'all should go back the original trouble, which not but verifies your answer, but likewise gives you exercise with both processes.

9. Make up your own practice problems

There are tons of practice problems that y'all can access in textbooks and online, just at that place are an infinite number of exercise problems right in your head. You tin tweak numbers or units in existing problems or create your own from scratch. Trade with a partner to double check your work and get extra practice.

x. Reuse exercise problems

Don't waste matter time looking for new questions every study session. Every bit long as you don't recall exactly how yous did the problem before, working the problem again will be beneficial. This is particularly useful for problems that you previously struggled with.

xi. Keep skills fresh

Fifty-fifty if you lot experience confident in a certain skill now, you might forget information technology by the fourth dimension the test comes effectually. While information technology nevertheless makes sense to prioritize studying your weaker skills, return to your strengths to keep them stiff. The best way to do this is do, practice, do!

12. Vary your resources

You lot probably first learned calculus in class. You lot may outset studying from the notes you took or a textbook you have. If you need more information, information technology's easy to look for a volume or an article on the net. You tin can also look up videos of people working issues, ask your teacher to work with you, or get a classmate to study with you. Processing information in dissimilar means is a learning technique chosen multisensory learning and has been proven to better academic operation.

13. Know when to enquire for help

We all take times when we need help. Maybe you lot've tried to relearn a topic and simply don't become information technology, or maybe you don't even know where to begin. If y'all've exhausted what you can practise by yourself, or even if you're just exhausted from trying, remember that you're not alone. One corking resource is your teacher. They will already exist familiar with your learning style and can either help you straight or evidence y'all to some slap-up resource. If you adopt working with someone your ain age, ask your classmates. They are in the same situation as you and are usually happy to collaborate. If you accept the resource, you may consider hiring a tutor or enrolling in a prep class. If not, ask a librarian to assist you discover resource, or find an online question board, such as Quora , where strangers can help answer questions.

AP® Calculus AB Examination: 5 Exam Day Tips to Recollect

1. Don't worry well-nigh studying the day of the exam

You are unlikely to learn or call back something in the few minutes before the test begins if you did non empathise it when studying earlier. Also, last-minute cramming often causes students to go stressed , which could lower performance.

2. Pump yourself up

Practicing positive self-talk like "I will practise my all-time" has been proven to improve math scores. Talking to yourself (although, in the exam room, non literally out loud) can aid overcome psychological barriers. Focus the talk on your effort and what you have control over in the moment. Accept two minutes in a ability pose to boost your conviction earlier inbound your test.

three. Watch your time
