What is the Best Online Multivariable Calculus Course - Distance Calculus

There are many online Calculus course options on the internet currently. They basically separate into the following 3 categories:

Free MOOC Courses
These are courses that are offered for free (or nearly so), but they do not offer academic credit for the courses. Some of these courses are awesome and are an excellent resource for the student enrolled in a for-credit online Calculus course.
Publisher Courseware
Many academic textbook publishers offer multiple-choice based "course systems" where you take the Calculus course by getting a login to their system (which is the same for multiple schools, but the logos at the top are different), and you engage the course via endless multiple choice quizzes - reading their online textbook, doing problems by hand, choosing multiple choice options.
If you like this kind of course, then you have many options in taking such courses. We, personally, feel these course systems are cold, boring, and monotonous.
Mastery Learning & Human Interation & Computer Algebra Software
These types of courses are our favorites, of course, because that's what Distance Calculus is modeled on. Other great courses using this type of system are NetMath from University of Illinois at Champaign-Urbana.

Here are some videos to explore our Calculus courses from Distance Calculus @ Roger Williams University. We will leave it up to you to decide which online calculus course is best!

Multivariable Calculus course can best be described as a "the first semester course of Differential and Integral Calculus to functions of many variables".

This course has many names, all being equivalent:

Calculus III
Calculus IV
Vector Calculus
Calculus of Many Variables
Calculus of Several Variables

At Distance Calculus, we call our "Multivariable Calculus" course as Multivariable Calculus - DMAT 355 - 4 credits.

Distance Calculus was the perfect answer to getting ahead in math over the summer of my junior year in HS. I was able to complete the entire course over the summer. The teacher was responsive and the course was understandable. Highly recommend.

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!

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.
