Flexible Time: Asynchronous Course Delivery

One of the most valuable features of Distance Calculus is flexible time. For working adults and working students, the issues of time and schedule are typically the biggest impediments to their academic careers - and our entire course design exists to remove those impediments.

Academic vs. Personal Schedules

Academic schedules at traditional colleges often do not fit well with working schedules or career schedules. A common example: after completing Calculus I in an evening course at your local college, you discover that Calculus II is only offered at 10 AM - right in the middle of your workday. Taking that time off three days a week may be theoretically possible, but it severely disrupts your job and your personal life. Or, as is often the case, your work schedule simply cannot be moved at all, and you cannot take Calculus II at your local college.

The "Life-and-Job Crisis" Problem

Even students who manage to get into a traditional course often run into a different problem: the life-and-job crisis that hits in the middle of the semester.

  • Your employer pushes a critical product launch and suddenly you owe nights and weekends to work for several weeks.
  • A family medical situation absorbs all the time you had set aside for studying.
  • You take parental leave for a new child during the semester.
  • You're pulled into an unexpected travel rotation or relocation.

A traditional lecture class cannot pause for any of those events. The class keeps moving on its weekly cadence whether you can attend or not. The only options are to drop the course (losing tuition and momentum) or to take an incomplete and hope you can finish independently later. The success rates of those plans are very low - finishing a stalled lecture course on your own without the structure or instruction support is genuinely difficult.

Distance Calculus Convenes Class When You Want

We solve this with three deliberate design choices working together:

  • Computer Algebra and Graphing Software as the primary student-instructor communication medium - you submit notebooks, we mark them up, you revise.
  • Real-time chat with the instructional team available most days, evenings, and weekends - you reach us when you have a question, on your schedule.
  • Asynchronous, recursive feedback loops - revolving feedback on your submitted work usually arrives within a day, so progress never depends on a fixed lecture time.

The result: you set the time for Calculus.

What This Looks Like in Practice

  • Two hours per night after the kids go to bed? That's when your Distance Calculus course meets.
  • Lunchtime at work, every weekday? That's when your Distance Calculus course meets.
  • One week working evenings, the next week working mornings? Fine. Whenever you want.
  • Saturday morning intensive sessions before family activities? Perfect.
  • Late nights during a slow stretch, and almost nothing during a busy stretch? Also fine.

Pause The Course When Life Demands It

If a genuine life or family crisis hits and you need to step away from the course for a month or two, that is not a problem with Distance Calculus. Tell the instructional team you need to pause, tell us roughly how long, and the course waits. When your break period is up, we'll start gently nudging you to help you get back up and running. There is no penalty, no missed deadlines, no scrambling to catch up to a class that has moved on without you.

Why Flexible Time Matters

For many of our students, flexible time is not a nice-to-have feature - it is the only way they can balance their life, work, personal, and family responsibilities against the time genuinely needed for calculus study to succeed. Distance Calculus is built around that reality from the ground up.

Courses Completed: Multivariable Calculus
Distance Calculus was a life saver! I needed an accredited program to complete multi-variable calculus for grad school and at the time was an American living in England. Being able to take the course on my own timeline, from my own home, was amazing! The content was thorough and the visualization exercises were very helpful for comprehension and understanding. This was an exceptionally, affordable, thorough, and convenient course that I found a lot of value in and I’m thankful it was available to me!

Courses Completed: Calculus II
I took Calculus II through Distance Calculus and can't recommend it enough. Being able to take the course at my own pace while I was working full time was tremendously helpful, especially since I hadn't taken a math course for 5 years prior. The instruction was excellent and the software they used to teach the course was intuitive and facilitated the learning process very well. This calc II class enabled me to take multivariable calc, linear algebra, and real analysis at Harvard University's extension school, which ultimately qualified me for the economics PhD program that I will graduate from next year. 8 years on, I'm still grateful to Professor Curtis and Distance Calculus.

Courses Completed: Multivariable Calculus, Differential Equations, Linear Algebra
After a really rough first year of calculus, I completed all of the second year calculus courses with Distance Calculus. It was like night and day the difference. My first year was so boring and monotonous. Multivariable Calculus, Differential Equations, and Linear Algebra through Distance Calculus were just so much different - so not boring at all. I thoroughly enjoyed these courses. So engaging.

Courses Completed: Precalculus, Calculus I
The courses were excellent. Very flexible and engaging and the platform offers a lot of upper-level courses. Dr. Curtis is an outstanding professor and very responsive. I would take again.

Courses Completed: Calculus I
After two failed attempts at my university, this course helped me understand Calculus. The live maths tool along with Dr. Curtis were especially helpful, allowing me to visualize concepts and expand my understanding. The explanations were clear, the examples practical, and I could learn at my own pace, which built my confidence. Thank you.
