After taking Precalculus with Outlier, you’ll never look at numbers the same way again.

This groundbreaking, cinematic course (from the co-founder of MasterClass) is the perfect gateway to math’s more advanced realms, whether you’re fulfilling a pre-req, getting ready for post-secondary math courses, or just need a refresher before diving into the deep end of Calculus.

Regardless of your reason, our passionate instructors will take you on a riveting ride that is sure to leave you with both a mastery of math’s building blocks and a profound new appreciation for an age-old discipline.

Get started


Outlier’s Precalculus course is taught by Kelsey Houston-Edwards, a charismatic instructor who’s renowned for her ability to clearly communicate complicated concepts, including for shows like PBS' Infinite Series.

Our guest lecturer, Po-Shen Loh, is a popular math YouTuber and professor at Carnegie-Mellon who has a knack for connecting math with everyday life in the most unexpected ways.

Hand-picked from dozens of candidates, we selected them for their passion for numbers, and their uncanny ability to bring big mathematical concepts to life.

For more information on refunds please refer to our Refund Policy.

  • Tutoring sessions will be scheduled to maximize compatibility with students’ schedules and availability. Exams are each open to take within a weeklong window, but all other course materials are available to you from the time the course opens through the end of the final exam window.

  • We are excited to be partnering with the University of Pittsburgh for our course credits. Upon successful completion, you will receive 3 college semester credits from the University of Pittsburgh, transferrable to other colleges and universities subject to review and approval by the receiving institution. When you transfer your credits, it will come as an official transcript from the University of Pittsburgh for Fundamentals of Calculus I (MATH 6210) and Introduction to Psychology (PSY 6010).

    Outlier is committed to ensuring that learners with accessibility needs have equal opportunity to succeed in our courses.

  • Early on in the process of designing Outlier, we found that many students use their laptops late at night, and don’t feel like staring into a lightbulb. Too much white in the background of videos and active learning would be fatiguing and unpleasant. We also think it’s pretty neat that we decided to do this before Apple shifted everything to dark mode.

  • Unlike delicious, calorie-free ice cream and most things that sound too good to be true, this is for real — $400 for 3 college credits that you can transfer to your school of choice. Our team has been working tirelessly to build a product that will make world-class education more equitable and more accessible, and change the way people define excellent education.

  • “Beta” is how we designate the first few real-world cohorts of any new course we launch. The course and materials have been created to our exacting quality standards, but like any good course are improved and modified with each class that goes through it to adjust to the student base. A “beta” period gives us the chance to tinker with pacing, improve the clarity, and fine-tune our Student Support for the course. It also lets you know that we welcome any and all feedback from you and you may find your requests swiftly applied. Your Outlier Beta course will still get you the same outcomes & credits as any other Outlier course, plus maybe a little extra attention from our Student Success team as they learn about how the course is working and if there’s anything we can do to make it better.

See for yourself!
