So math... it can be kind of challenging at times can't it?

 

But you know what? It’s not a problem if you’re not head-over-heels in love with solving for x.

 

Really, it just means you’re in good company with at least 85%* of the rest of the population who also have a tough time with math.

*My own estimate—not based on official research. But let’s be honest, it’s probably 85% or more.

 

But it does become a problem when your annoyance with solving for x gets in the way of following your dreams.

 

Like when failing a math class means you won’t graduate on time. Or when math is so hard that you have to change majors. Or when you know you’ve got no chance at a decent GRE score to get into that grad school program you’ve been lusting after for years.

 

When things like that happen, it’s just not fair. We all deserve to achieve our dreams—math nerds or not.

 

It’s why I started working as a math tutor in college. And why, even though I graduated with a degree in psychology, I kept tutoring math via YouTube.

 

I loved helping students uncover those little “Ah-ha!” moments when math theories actually clicked for them enough to pass their tests, so I didn’t stop.

 

And while YouTube videos were a great first step towards helping lots of students at once, I knew I could help students uncover even more of those “Ah-ha!” moments with things like:

  • Formula cheat sheets that make math terms way less confusing
  • Notes that show you what’s essential to remember, what’s safe to forget, and slash study time significantly
  • Quizzes to make sure you “get it”
  • An open Q&A where I can answer questions when things don’t totally click

 

So I created CalculusExpert.com.

Get ready to pinch yourself, because math really can be this easy.

 

I’ve helped students who would inevitably fail squeeze by with a grade 10% higher than the one they needed to pass. And people who failed high school math get accepted at prestigious universities for degrees in mathematics.

 

I don’t say stuff like that to brag, just to be totally honest with the fact that math is possible to figure out, and even if you feel like you’re cursed in that area, there is still hope for you.

 

Even if you’re not a math whiz, math can still be easy for you.

 

Yes, even if you’re in a Calculus III class and everyone else in your class is failing miserably.

 

Whatever reason you’re taking math classes for—to become a scientist, doctor, or just complete the math requirements for your liberal arts degree—there’s one fact you can’t run away from: you’ve got to pass this class or change your major.

 

And if you change your major, you’ll also have to change your life plans.

 

Which is so not fair.

Because your dream isn’t a partial derivative. And it shouldn’t be as hard as one, either.

 

I have students from all walks of life studying inside Calculus Expert:

  • Traditional, four-year college students who just need to pass a class to graduate on time
  • High school students in the running for valedictorian status (and all the scholarships that entails)
  • Students who need to keep their grades up to keep their scholarship money
  • People studying for the GRE so they can get into grad school
  • Professionals who want to change their career path, but need a foundation in math to make that happen

 

And here’s how Calculus Expert has helped them:

Not only reinforces what was covered in class, but also speeds up the time it takes to complete homework.
I’m an almost 40-year-old mom of 3 that went back to school to be a math teacher… with one night of studying before my final a week and a half ago, you helped me go from being 100% in the dark to [passing my test] with an 87%!! Never in my wildest dreams did I even think I would have done that well on that midterm.
I passed my exams and was subsequently accepted to study a BSc Mathematics and Economics degree at the University of London. All this at the age of 34, after failing math in high school.
At one point during Calc II I thought about dropping math entirely from my schedule, but since joining Calculus Expert, I’ve added a math minor.
My first two term tests were 31% and 33% after the curve. I considered dropping the class…. I checked my marks today and I got a 73% on my exam, and I passed the class!
When I had a question you always got back to me in just a few hours. The way you explained the answers to all of my questions was in a way that made Calculus fun and easy… I was able to get a 97.6 in Calculus!

And you know what?

 

These students are just like you.

 

But since they made the decision to get help instead of letting math beat them up, they passed their classes, achieved their dreams, and now have lives they wouldn’t have if they’d let math get in their way.

What you get inside of Calculus Expert

Here's what you get access to when you sign up as a student of Calculus Expert:

 

Every single math course I've ever made

The fundamentals of middle school math all the way to advanced calculus. Access to every course and lesson you need to ace your class.

1.

 

2.

A structure that makes sense

An optimized course flow to make studying and homework faster. So you “get it” in less time than you would figuring things out on your own.

 

3.

Open Q&A sections

Still don’t understand something? I check into the Q&A sections of the courses at least once every weekday. Ask away. I’m happy to help.

 

And here's what you get inside of every single lesson:

 

Videos

 
 

Watch over my shoulder as I solve problems for every single math issue you’ll encounter in class. We start from the beginning. I explain the setup and why I set it up that way, the steps I take and why I take them, how to work through the fuzzy middle parts, and how to simplify the answer when you get it.

 

Notes

notes-icon.png
 
 

The notes section of each lesson is where you find the most important things to remember. It’s like Cliff Notes for books, but for math. Everything you need to know to pass your class and nothing you don’t.

 

Quizzes

quiz-icon.png
 
 

When you think you’ve got a good grasp on a topic, you can test your knowledge without affecting your grade by taking one of our quizzes. If you pass, wonderful. If not, you can review the videos and notes again, or ask me for help in the Q&A section.

 

Below each lesson there’s a place for you to ask me questions. Anything goes, as long as it’s math related. There’s even a function for you to upload a picture of your work to show me exactly what you’re getting hung up on.

 

Plus, I've made all of the videos, notes, and quizzes specifically for non-math minded people.

 

Your grade is about to get a serious lift. #winning

Hi, I'm Krista. The nerd behind all these magical math tricks and the tutor that walks you through every single Calculus Expert lesson.

 

I’ve always been kind of nerdy… when I was young, my dad would entertain me by writing out math problems on napkins for me to solve.

 

And rather than having this huge, insatiable love for math, the thing I loved was reverse-engineering the information available to solve a problem that seemed tough, but actually wasn’t.

 

In college, I majored in Psychology, but found myself translating the skills I used on those napkin problems to help me in Calculus.

 

For most students, college-level Calculus is a big deal. It’s hard to understand. And tons of students have to get extra help or retake it.

 

And while I personally enjoyed math, I hated hunting around in my textbook for missing information, or spending huge amounts of time solving problems that I knew should have been more straightforward.

 

I looked at what my professors were teaching, took out the confusing vocabulary, noticed patterns in how the problems were actually solved, and eliminated all the confusing theory.

 

And it worked. I passed with flying colors.

 

And when I finished, I worked as a tutor to help other students pass their math classes, too. I was surprised at how well the students I tutored performed on their tests compared to the rest of their class.

 

And even though I graduated with a Psychology degree, I still wanted to tutor. I started making some simple calculus videos for YouTube, and was floored at how much I could help people… and how many people I could help with just one video.

 

Watching my YouTube channel grow to thousands and thousands of subscribers gave me the idea to take my online tutoring to the next level.

 

So I started Calculus Expert, where I teach math students easier ways to think about and solve hard math problems, helping them pass their classes with good grades and graduate on time.

 

I also really wanted to start it because I noticed there wasn’t anything out there exactly like Calculus Expert.

 

There’s certainly plenty of virtual math tutors for hire, but most of them follow a traditional textbook method. And none of them offer you unlimited hours and subjects of tutoring for only $27 per month.

What Calculus Expert helps people like you achieve

 

I get a lot of students telling me that hard math subjects FINALLY clicked for them after they watched my videos and read through the non-gibberish course notes.

 

I’m addicted to seeing people uncover those “Ah-ha!” moments, and I’ve made sure that every single lesson will deliver that same feeling of immense relief, giving you the easiest experience with math that you’ve ever had.

 

Yes, the easiest experience with math you’ve ever had.

 

(Except for maybe those subtraction “problems” you solved in Kindergarten by eating Skittles.)

 

Math is hard. That’s no kind of understatement.

 

So I teach you how to learn math in a non-math way your brain can actually handle.

 

I might not use the exact same wording as your professor, but I’m guessing you don’t care. (I’m also guessing that’s why you’re here in the first place.)


Inside of Calculus Expert, I teach you the techniques I learned for myself that made math easy for me. Everything’s still 100% technically correct and sound and will get you the right answer… it’s just an approach that looks at math from a non-number crunching perspective.

Here’s what my students say about Calculus Expert:

 
I just wanted to pass calculus because I know it’s hard and it’s needed for engineering… I really appreciate how you never skip a step no matter how minor it is.
Krista’s the best, and she skips the BS in the exact way my professors will not
I wish you were my prof through applied linear algebra!
I never feel overwhelmed or bored with the courses. I’m learning at just the right pace.
Thank you for following the calculus curriculum so closely. Your explanations are so much easier to understand than my textbook.
It helped me turn around my calculus grade. I went from having a C in calculus 1 to A’s in calculus 2 and 3, and I am also using the site to review concepts on geometry and algebra for the GRE
The PDF notes are AWESOME!

Got some questions about Calculus Expert?

I thought you might. ;)

Here I’ve answered the most common questions students ask before they sign up.

Click on the question you have to read its answer, and if I don’t fully answer your question here, get in touch using the form at the bottom of the page.

 
 

Before Signing Up

 

1. Is this just for people taking calculus?

No.

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

I do have a higher focus on the harder math courses because that’s what most people have the hardest time with, but the 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?

My 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 my YouTube channel like you can in the 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 helped 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 had 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 I’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 my full-time job, I pocket a little bit of it too.

 

2. What does the $27 per month include?

  • Access to all of the 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 the 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 the 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 the 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?

That's why we offer a 30-day free trial.

Which means you can try Calculus Expert for up to 30 days, and if you don’t think it’s going to help you pass your math classes, you can cancel with just a couple of clicks.

 

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 it so much that you want to keep sending me $27 per month, which I will happily accept.)

Canceling is easy.

Click on the arrow by your name in the upper right-hand corner, click on “Settings”, then on the “Billing” tab, and then on the “Cancel Your Subscription” button.

You’ll have access until the end of the current billing cycle, but you won’t be charged for the next month (or any month after that), and your account will be deactivated.

 

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 me, 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 https://www.calculusexpert.com.

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 me 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 me know by sending me a message via the contact form on the bottom of this page. I'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.
