The majority of the reviews focus on course enjoyment, the importance of understanding the concepts and the exam requirements, and the need for regular consistent practice (especially for FRQs).

1.      Many students really enjoy AP Calculus and found the classes easy

“It’s not a very difficult class. I had a great time learning the material and hardly had to study in the days leading up to the exam and I got a 5. Pay attention in school and you’ll be golden.” – AP Calculus AB/BC Score: 5

If you love math, this is a pretty easy course. If you hate math, it will be the worst course in your schedule and you will have to work hard to succeed.” – AP Calculus AB/BC Score: 5

“In my experience, the teacher you have for the course will largely dictate your score. Secondly, if you have a proclivity for math and want to learn something other than algebra in high school, this course will be one of the most interesting AP courses offered. As always, practice FRQs and (un)released MC sections.” – AP Calculus AB/BC Score: 5

“If you really enjoy math, then BC won’t be as bad as you think (for both the class and self-studiers). Don’t blow off homework/practice problems and actually try to understand why each formula or theorem works.” – AP Calculus AB/BC Score: 5

“This is a good class to get an easy 5 if you have a good teacher and work ethic. It was a lot of homework (like at least an hour a night, for real), but if you correct all your worksheets then you’ll be good for the unit tests.” – AP Calculus AB/BC Score: 5

If you’re good at algebra, this course will be super easy. The only hard part is learning conceptual meaning of it. The AP exam is super easy, as long as you study.” – AP Calculus AB/BC Score: 5

“Easier than it looks. A strong foundation of derivatives and integrals will get you through the course.” – AP Calculus AB/BC Score: 5

2.      AP Calculus AB and BC require a good understanding of the concepts!

“Studying is all about getting the concepts down and applying them. The FRQs are going to kill you if you can’t think about how to apply everything you learned.” – AP Calculus AB/BC Score: 5

“Make sure you understand the concepts behind the problems. The actual AP exam does not have many “memorization” questions, instead requiring you to manipulate equations. Fairly straightforward if you understand the prerequisite math and pay attention in class – would not recommend self study, though.” – AP Calculus AB/BC Score: 5

“This class was fairly difficult at first but once you have the core concepts down it’s a breeze. This class is definitely more about understanding how these concepts work, rather than knowing how to plug numbers into formulas like previous math classes. Keep up with your homework and do practice problems and you should be good (as long as you have a decent teacher).” – AP Calculus AB/BC Score: 5

“Learn it conceptually, don’t memorize.” – AP Calculus AB/BC Score: 5

“Make sure you understand all concepts that you are taught in class. concepts build on top of one another, and a misunderstanding of once thing can lead to your entire grade suffering in the future” – AP Calculus AB/BC Score: 5

“Study the content. Practice makes perfect–literally. The concepts aren’t hard to grasp as long as you take the time to practice and look over your notes.” – AP Calculus AB/BC Score: 5

3.      Knowledge of algebra and working without a calculator are also a plus!

“Make sure your algebra knowledge is good before taking it. Many people are able to do the calculus but fail with the algebraic areas that are needed before and after the calculus step.”’ – AP Calculus AB/BC Score: 5

“Know how to do every problem without your calculator. The calculator can be helpful, but it’s useless if you don’t know what you’re doing without it.” – AP Calculus AB/BC Score: 5

4.      Students found understanding the exam format, requirements and curve really helpful

“Just do a lot of questions before hand, most of the questions on the test are really straight forward and there are no trick questions. If you know like 70% of the material on the course you can get a 5 because of the huge curve.” – AP Calculus AB/BC Score: 5

“Find out what you have to do to get an A every semester. … For the test, AP Calc is the BEST because there’s like 50 years of practice tests you can use. The material change very little from year to year so if you COMPLETE 10 tests and go over every question you go wrong and figure out how to do it correctly, I GUARENTEE you will get a 4+.” – AP Calculus AB/BC Score: 5

“This exam is easier to study for than you would think, the questions tend to be very similar every year, the frqs can be easily practiced through the past AP exams. … The class in general isn’t much more difficult than previous math classes.” – AP Calculus AB/BC Score: 5

“Make sure you review your AB subsection if you’re taking BC! ~70% of the BC exam is AB content!” – AP Calculus AB/BC Score: 5

“The FRQs are your BFF, because with enough practice exams you will know exactly what questions they’re gonna ask you. If you can consistently score at least 6/7 points on each FRQ you can bomb the MC and still get a 5” – AP Calculus AB/BC Score: 5

“Easy to get a 5. Helps to have taken AB before BC but still fine if you haven’t. BC gets easier for non AB students in the second half of the course, if you take it in school.’ – AP Calculus AB/BC Score: 5

Taking the BC exam over the AB exam is almost always worth it. Not much additional content to study and you get an AB subscore anyway.” – AP Calculus AB/BC Score: 5

6.      Students found self-studying manageable – especially BC

“I took AB and self studied BC. I found it fairly easy to do so, and I think I had a decent chance of acing the exam had I not made so many sillies.” – AP Calculus AB/BC Score: 5

“Taught myself BC, took AB class at school. I’m biased but the BC material wasn’t too hard, just use Paul’s online math notes and math with Mr wood. If you understand why things work then you’re set.” – AP Calculus AB/BC Score: 5

What Does It Take To Succeed: The AP Calculus AB Exam

What is AP Calculus AB? Course Outline & Requirements

According to College Board:

“AP Calculus AB is designed to be the equivalent of a first semester college calculus course devoted to topics in differential and integral calculus.”

Prerequisites: “before studying calculus, all students should complete the equivalent of four years of secondary mathematics designed for college-bound students”. Students should also “understand the language of functions”, especially sine and cosine.

You will develop skills in:

  • Determining expressions and values using mathematical procedures
  • Translating mathematical information from single to multiple representations
  • Justifying reasoning and solutions
  • Using correct notation, language and math to communicate solutions

The exam consists of one 3 hour 15 minute exam, with 50% (105 minutes) of multiple-choice questions (MCQs) and 50% (90 minutes) for 6 free-response questions.

For more details, see: College Board’s AP Calculus AB course page.

Examiners’ Reviews: Takeaways From AP Calculus AB Test Assessors

College Board released the following official comments about the 2021 exam results:

Multiple choice section

  • “As usual, students scored significantly higher on the multiple-choice section than on the free-response questions.”
  • “AP Calculus AB students demonstrated strongest mastery of Unit 4, Contextual Applications of Differentiation, with 11% of students earning a perfect score across the questions about this unit.”
  • “Students generally scored least well on Unit 7, Differential Equations, in which 4% of students answered all questions correctly and 9% answered none correctly.”
  • “Students generally scored less well on questions about analysis of functions than on questions about change and limits.”

Free response section

  • “The strongest results were typically on Question 4, the graphical analysis. 14% of students earned 7–9 points out of 9 possible.”
  • By far the most challenging question on this year’s exam was Question 3 (area-volume; disc method); 3% of students earned 7–9 points out of 9 possible.”

For best results, you may therefore want to consider investing a little extra study time on Unit 7 “Differential Equations”, analysis of functions and area-volume.

How To (Self) Study APs Calculus AB and BC: Advice From Class Alumnae

Practice, practice, practice for the exam – especially for FRQs

“For calculus practice is the most important thing. If you can do all the old practice exams then you will be guaranteed a 5” – AP Calculus AB/BC Score: 5

“***Drill FRQs.*** They are essentially copypasted from year to year, so if you do enough of them and become familiar with common question types, you’ll be able to fly through them come exam day.” – AP Calculus AB/BC Score: 5

“Be sure to go through every FRQ from previous exams before taking the exam; the layouts of the questions are usually very similar, so you’ll know exactly what you’ll need to do or expect. … Finally, be sure to dig up a lot of practice MC questions and get a good feeling for those; MC scores can easily make up for an FRQ that you screwed up on, and can really help you keep your composure throughout the test.” – AP Calculus AB/BC Score: 5

“Solve a bunch of FRQs. You’ll get the general sense of how to approach different types of questions and concepts.” – AP Calculus AB/BC Score: 5

“Take as many practice tests and FRQs as possible. Alvead is a good place to get old AP tests.” – AP Calculus AB/BC Score: 5

“Do a lot of the released FRQ’s and make sure to check the scoring to squeeze out as many points as you can.” – AP Calculus AB/BC Score: 5

Specific skills are helpful throughout the course for memorization

“Start looking at FRQ problems after you’ve done applications of derivatives, I’d say. That’s when you can start some of them. From there, make sure to get how to use the concepts both algebraically and graphically. It’ll save you a world of trouble. Other advice: learn how to derive inverse trig derivatives. It’s easy to do, and it stops you from having to memorize everything. Integrals may require some memorization, though.”- AP Calculus AB/BC Score: 5

Make the most of different study resources – from study groups and teachers …

Talking about any problems you’re unsure of with another student helps a lot!! For FRQs, start practicing as early as November – it really helps! Drill past FRQs – they’re the best resource!” – AP Calculus AB/BC Score: 5

“Ask questions to UNDERSTAND why you do what you do to solve a question” – AP Calculus AB/BC Score: 5

“When you’re learning derivatives and integrals, make flash cards for them and study frequently. Also begin doing FRQs and practice tests a good 2-3 months before the test itself.” – AP Calculus AB/BC Score: 5

Do the homework every day, make sure you know the three theorems or whatever (IVT, EVT, MVT) and how to recognize when to use them, go to the AP sessions for at least the topics you might have issues with (my teacher gave extra credit for going so I would go regardless if you aren’t busy), talk with your teacher if you have issues with anything” – AP Calculus AB/BC Score: 5

… to online resources and study guides

“Take advantage of the past FRQs that the College Board releases! It also doesn’t hurt to have a prep book to go to whenever you would get stuck on a certain concept!” – AP Calculus AB/BC Score: 5

“I highly recommend everyone who is starting this course to watch 3Brown1Blue’s youtube series “Essence of Calculus” This series is the best resource you can get and whether you enjoy math or not, you will learn a lot.” – AP Calculus AB/BC Score: 5

“Princeton Premium is more worth than Princeton normal. The flashcards are also a big help. These two are a MUST.
Also, it is highly recommended that you have a good math background, especially if you plan on self studying.” – AP Calculus AB/BC Score: 5

“I would recommend going onto the College Board website and doing all the free response questions from previous AB and BC Calc exams. If you can do those questions and repeatedly scoring a 7 or higher, you’re set for the exam.” – AP Calculus AB/BC Score: 5

Success in AP Calculus often comes down to dedication and preparation!

“I just did every single practice FRQ I could find from the 1990s to today. I made a 40 or so page study guide as well.” – AP Calculus AB/BC Score: 5

“Do all of the proofs you can, practice a lot, and teach yourself polar/parametrics/vectors before the class. You have enough time to teach yourself differential equations and multivariable if you do it right.” – AP Calculus AB/BC Score: 5

Do ALL of the homework, especially for BC, and you should be adequately prepared for the AP test” – AP Calculus AB/BC Score: 5

“Do as many reviews as you can. Grab ahold of all the material you can. Something that really helped me was rewriting all my notes the weekend before the exam.” – AP Calculus AB/BC Score: 3

“Start reviewing in February. Review as many FRQs from recent years as you can with your friends. Stay up to date on the homework and especially review Calc II concepts.” – AP Calculus AB/BC Score: 3

“When you’re learning derivatives and integrals, make flash cards for them and study frequently. Also begin doing FRQs and practice tests a good 2-3 months before the test itself.” – AP Calculus AB/BC Score: 5
