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 needed to finish the Business Calculus course very very very fast before my MBA degree at Wharton started. With the AWESOME help of Diane, I finished the course in about 3 weeks, allowing me to start Wharton on time. Thanks Diane!

Dr. Curtis's courses are very difficult, but they are definitely worth it! I took Calculus 2 from Dr. Curtis in my senior year of high school and went into a combined Calculus 2 and Calculus 3 course my first year of college. This course prepared me, and I found that I already knew much of the Calculus 3 coursework. The most difficult part of these courses, in my opinion, is pacing yourself. If you can keep yourself on track, then you are all good to go!

I will preface this review by saying that if you are looking to take the easiest course possible, cheat through it, and learn as little as possible, this is not the course for you. Below, I will provide my uncensored opinions to this course:

First, this course uses software called LiveMath. This software can be a little bit challenging to get the hang of, but once you do get the hang of it, it's super easy. Remember that for all new things, it takes a bit to get used to it. Overall, I was highly satisfied with this course. I thought that the instructions were extremely detailed, including a video and a textbook explaining every different concept. In addition, this course offered exposure to a lot of different aspects of finite math. I think that many would agree with me on the following, that, you know, when a teacher is passionate about what they are teaching, it is so much more enjoyable, and you can definitely see that in this course. This course can be challenging at times. Maybe it'll be easy for you, maybe it'll be hard, but I think it's important to remember that the things that challenge us are, you know, the things that make us learn and the things that make us better. There's also a math chat option for if you need help or if you have any questions. Overall, I would recommend this course. I actually initially went into this course looking for an easy course to just help me get the credit requirements, but it ended up being an amazing learning experience and completely shifted my perspective on math overall. And another thing that I thought was great in this course is throughout so many different lectures, the professor would explain how each different thing can be applicable in life. And I think that, you know, that is a lot of what people think about when they are learning something. They're like, will I ever use this? Do I need to learn this? And a lot of this actually is really applicable. And I think that even if, you know, you may not be doing these math equations in your future, I think that, you know, the psychology behind these and the rules can be applied to so many different fuacets of life.

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.
