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.

I've taken Multivariable Calculus, Linear Algebra, Differential Equations, and Probability Theory through Distance Calculus. All four courses were awesome. Dr. Curtis and the TA's were very responsive and helpful.
The biggest advantage of these courses, compared to taking a traditional course, is that in addition to the theory, I was forced to also think computationally. I have become quite adept at using LiveMath and Mathematica for doing calculations and plots.
All of the courses were accepted for credit transfer (Johns Hopkins University)

This course provided an excellent chance to learn about Calculus...again. I took calculus in high school, but I learned so much more with this course!
It does take a good amount of time to do all the lessons, so definitely keep on top of them, but all the exercises helped me to really understand the material. And the nice thing is you can do it on your own time at home.

This is the most interactive and productive online course I have ever taken. I had taken calculus before but never understood some of the underlying concepts until I took this course.
If you want to really learn calculus in a way that will stay with you for the rest of your life, take this course.

Courses Completed: Calculus II, Multivariable Calculus, Differential Equations, Linear Algebra
After completing all the math offered by my highschool, I switched over to Roger Williams for Calculus II and onward. Overall, it has been a pretty great way to understand the topics online, with transferrable college credits. The exams are not terrible, and the courses cover the vast majority (if not all) of topics covered by traditional courses, with some unique ones added to. So far, I have taken four courses, with another one or two before I graduate.

The only problem with the course is the lack of pen and paper work. This shouldn't come as a crazy surprise with an online course, but there is not much emphasis on symbolic computation. Mathematica or other software does most of the heavy computation for you. The lectures usually show how to solve the problems through paper, but those skills are rarely put into practice. Literacy Sheets act as a way to do some of that (especially with the Calculus II & III course).

All in all, this isn't a huge issue. I just memorize and practice things like double integration, Laplace, ODE solving, matrix diagonalized form, row operations, etc. With a little outside work, this resolves itself. Without Roger WIlliams, I probably would not have been able to take any of these math courses in highschool.

So overall, a great choice for highschool advanced math, especially with transferrable credits.

The professor as well as the TAs give great feedback when you need help with problems and the videos are great at explaining concepts. Return time on work is good and the work is not too much to handle.

Courses Completed: Linear Algebra
This course gives a perspective on Linear algebra that no traditional course does. I’d say i gained much more intuition for this subject from the DC course than my friends who took traditional courses elsewhere. As a cs major, this version of learning with visualization has helped me a lot in understand ML models. However the course doesn’t have videos for the last 2 chapers so i had to self learn with the mathematica notebooks. Response times are a little slow but since it’s a remote class, i guess it’s justified. Overall amazing course and definitely take this over traditional lin alg classes.
