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

Welcome to Krista King Math

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 of 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


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

Algebra course path

We’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.

We 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.


We have students from all walks of life studying inside CalculusExpert:

  • 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 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 CalculusExpert, 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.

Course library

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



Math 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.



Math notes

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.



Math quizzes

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.



Questions and answers for math

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, we’ve made all of our videos, notes, and quizzes ourselves—specifically for non-math minded people.

Want to see it for yourself? Here’s a video to walk you through it:

I Still Don’t Know if It’s Right for Me….


Not sure if $27/month (or $12.25/month if you buy the yearly plan) is worth it?

Think about this:

One-on-one, private tutors usually cost $30 to $40 per hour.

Just one extra credit hour can cost $250 to $300 at a public university for in-state students. Multiply that by the three hours of a typical math class, and you’re looking at an additional $750 to $900 to your school bill if you drop a class mid-semester.

If you graduate half a year later, you could be missing out on $20,000 or more in salary for that year.

If you don’t keep the minimum GPA required for your scholarships, what kind of life cost are you looking at there?

Suddenly $27/month doesn’t seem that bad, does it?

And with a 30-day 100% money-back guarantee, there’s really no reason not to at least try it.
