Questions about Krista King Math

Got some questions about Calculus Expert?


I thought you might. ;)

Here we’ve answered the most common questions our students ask us before they sign up.

Before Signing Up

1. Is this just for people taking calculus?



Though our site is called Calculus Expert, we’ve expanded way beyond calculus and have math tutoring courses with levels as early as middle school level math.

We do have a higher focus on the harder math courses because that’s what most people have the hardest time with, but our modules help anyone struggling with Pre-Algebra, Algebra, Geometry, Trigonometry, Calculus, and advanced math.


2. Can’t I just get all of this on your YouTube channel?


Our YouTube channel is a great resource for quick help to understand math concepts, but it lacks a lot of what makes a subscription to Calculus Expert truly worthwhile, especially if you’re really trying to conquer math.

For example, Calculus Expert students get access to notes, quizzes, and formula sheets that often make the difference in kind of getting a math concept enough to maybe pass, and the confidence to walk into the exam room knowing you’re going to own it.

Also, the YouTube videos aren’t necessarily organized in a manner that’s meant to be connected. They’re all quick help videos organized by topic, but you can’t really dig your fingers in and explore a topic from front to back on our YouTube channel like you can in our course library.


3. What makes your approach to math different? Aren’t you just re-explaining the textbook concepts over and over again?


You’ll never see me explaining a mathematical concept or working through a problem with the same kind of gibberish, jargon-y language traditional textbooks and old school professors love to use.

In fact, the only reason I “get” math so well now was because I found ways to reverse-engineer the concepts for easier understanding so I could pass my own college math classes in my days at Notre Dame.

I didn’t want math to be so hard, so I found ways to make it easier. It worked so well that I started tutoring other students with these same methods, and now I teach them inside Calculus Expert.


4. What kind of experience do you have in math, anyway?


Like you may have read, I’m not a math professor. I didn’t even study towards a math degree in college.

But I did spend a fair amount of time figuring out how to make math easier for myself and the other people in my math classes. Mostly because we just wanted to pass.

But after I saw how well those methods worked for the classes I was taking, I started working as a math tutor, helping other students struggling with college-level math “hack” it once and for all so they could finish their degrees on time.


5. Why should I believe that this will work for me?


I know you might think that I’m some kind of weird math nerd with a brain that works better with numbers than most people's’.

That’s definitely not the case, but you don’t have to take my word for it.

Calculus Expert has helped people who failed high school math get accepted for math-based degree programs at elite universities.

It’s middle-aged adults who haven’t touched math since high school earn a B on tests after just one night of studying our material.

It’s helped college students who thought they hand no other option but to drop a class and take summer school become so confident in math that they decided to get a minor in it.

We’ve helped students achieve valedictorian status that wouldn’t have been possible without understanding math, and have helped countless students who were in danger of failing pass worry-free.


Pricing, Payments & Subscriptions

1. Why $27 per month?


Because we’ve got to pay the bills somehow.

The $27 per month you pay goes towards maintaining the website, user support, and the production of more tutoring modules and videos.

And since this is our full-time job, we pocket a little bit of it too.


2. What does the $27 per month include?

  • Access to all of our lessons, from basic fundamentals to brain-bending calculus.

  • An easy-to-navigate course interface to find exactly what you’re looking for.

  • Course notes so good they’re better than your textbook. In fact, you can probably just forget your textbook.

  • Practice quizzes so you know when you finish a unit if there’s anything you need more help on.

  • Formula sheets that’ll help you finish studying in record time.

  • Access to our lesson-based Q&A area where you can ask for help if you need it, and where I’ll be happy to answer. Kind of like your own personal, virtual math tutor.


3. How long do I have to subscribe for?


We run subscriptions on a month-by-month basis, so if you only need our material for a month while you cram for exams, you can choose to cancel your subscription after that time period.


4. What if I want to pause for the summer when I’m not taking any math classes?


Don’t worry, we’re 100% not offended that you don’t want to spend your break studying math online. We get it.

That said, if you’re not taking summer classes or have a semester without a math class, you can choose to pause your subscription for 30, 60, or 90 days.

While your subscription is paused, you won’t have access to our material, but it’ll un-pause once the set time limit is up and you’ll be back in action.

Also, at any point during the pause period, you can change how long you want the pause to last, unpause completely, or cancel.

We’ll send you an email reminder 7 days before your pause is up just to make sure you stay in the loop.

To pause your subscription, click on the arrow by your name in the upper right-hand corner, click on “My Account”, then on the “Payments” tab, and then on the “Pause My Subscription” button.


5. What if I don’t like Calculus Expert?


We offer a 30-day money back guarantee.

Which means you can try CalculusExpert for up to 30 days, and if you don’t think it’s going to help you pass your math classes, you can cancel, let us know that you’d like a refund, and we’ll happily refund you.


6. How do I cancel my subscription?


Once you’ve dominated math to the point that you don’t have to deal with any more annoying math classes or textbooks, make sure to throw yourself a party. Because that’s a serious accomplishment.

You’ll also want to cancel your subscription. (Unless you just love us so much that you want to keep sending us $27 per month, which we will happily accept.)

Canceling is easy.

  1. To cancel your subscription, sign in and select "Settings" on the menu under your name in the upper right corner.

  2. At the bottom of your profile, select "Billing."

  3. Then select “Manage Subscription.”

  4. Select “Cancel Subscription.”

  5. Confirm again and your subscription will be cancelled.

No further charges will be made to your card. You will retain access to all content through the end of your current billing period. At the end of the billing period, the Subscribe button will become available again and you will be able to resubscribe at any time. 


7. How do I change my credit card or payment method?


Click on the arrow by your name in the upper right-hand corner, click on “My Account” and choose the "Payment" tab.

You’ll see options to update your payment preference.


Inside Calculus Expert

1. What’s the deal with the points I see beside of each lesson?


As a student of Calculus Expert, you can enroll in as many courses as you want.

Once you enroll in a course, you’ll see that each step of the course has a point value attached to it. When you complete the step, you earn those points.

Unfortunately, the points aren’t brownie points. (Unless you’re wanting to earn brownie points with us, in which case you can double them.) Instead, they go towards your “report card” so you can see the kind of progress you’ve made since you’ve started studying with Calculus Expert.

Winning at math can feel like a total slog, so we use the report cards as an easy way to remind yourself how awesome you are and how awesome you’ve become since you decided to step up and make math your little servant minion.


2. I can’t log in. What’s wrong?


Make sure you’re using the right url, which is

Click on “Sign In” in the upper right-hand corner to enter your username and password.

If that doesn’t work, try resetting your password by clicking on “Forgot your password?”

If it’s still a no-go, fill out the contact form at the bottom of this page to get in touch with us to sort it out. And sort it out we will.


3. Can I change my password?


Yes. And there are two ways to do so.

If you’re logged into your account, click on the arrow by your name in the upper right-hand corner, and then click on the “Password” tab.

If you’re not logged in, click on “Sign In” in the upper right-hand corner and click on “Forgot your password?” to have a reset link sent to you.


4. Why won’t the videos play?


If at all possible, try to use Chrome, Safari, or Firefox while studying through our modules.

If you’re using Internet Explorer, make sure you’ve got at least version 9 or higher.

Sometimes videos don’t play because you need to install the latest version of Adobe Flash Player or Quicktime.

If you’ve tried all of those things and the videos still aren’t playing, let us know by sending us a message via the contact form on the bottom of this page. We’ll work with you to get it sorted out ASAP.


5. I’m getting a little tired of the email notifications. How do I turn them off?


Don’t want your math emails flooding your inbox?

No problem. Click on the arrow next to your name in the top right-hand corner, click on “My Account” and then click on the “Notifications” tab. There you’ll be able to un-check all the notifications you don’t want to see anymore.
