Excellent! I have already learned so much and LOVE the teaching style.



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

about the fact that Sequences & Series are 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, Sequences & Series can still be easy for you.

THE Sequences & Series COURSE


If Calc 2 is hard, no worries. For most people, it’s harder than Calc 1 and Calc 3. Finding the volume of a 3-D solid object might sound easy at first… but not when you have to use curves and intersecting lines to figure it out. But don’t worry, we’ll help you wrap your mind around it and pass your test with flying colors. Learn more

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


1. My Sequences & SEries course and Every other 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.

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

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.


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.


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