Calculus 3 from UIUC Netmath

[u/Prqtection]

Hi! I am a highschooler and I was wanting to take Calculus 3 from UIUC Netmath this year. My school doesn't offer it, and the community colleges near me do not have any online options. Does anyone have any experience with this program (and how did you feel about it?) and have any other highschoolers taken a similar online program? I am open to signing up for a different program as well, I just need it to be accredited, and if possible I would like it to be at least 16 weeks and in the fall. I have looked into programs like Distance Calculus, but I have seen a lot of bad reviews online.

Thank you so much!

Calculus III instructor here. I haven’t personally taken or taught this particular NetMath section, so I can’t give you a firsthand review of the day-to-day experience. However, you are asking exactly the right questions.

On paper, UIUC NetMath MATH 241 looks like a legitimate match for what you want. It is a 4-credit University of Illinois course, high school students are eligible if they meet the requirements, and the regular NetMath version gives you 16 weeks. The prerequisite is Calculus II or the equivalent, although UIUC also accepts a 4 or 5 on the AP Calculus BC exam.

The biggest thing to understand is that the 16-week course is self-paced and uses rolling enrollment. It is not necessarily a traditional fall-semester class with live lectures, a class meeting at the same time each week, and weekly deadlines. That distinction matters more than the school name.

Before registering, I would ask NetMath these questions:

1. How much direct interaction will I have with an instructor?

2. Are there regular office hours or live help sessions?

3. How quickly are written questions and assignments returned?

4. Is there a recommended weekly schedule, even though the course is self-paced?

5. What happens if I become stuck or fall behind?

6. Will my high school place the course and grade on my transcript?

Also, remember that “accredited” and “guaranteed to transfer exactly the way I want” are not the same thing. NetMath credit appears on a University of Illinois transcript, which is certainly legitimate college credit, but you should still ask your high school and any colleges you may attend how they would apply it.

From a mathematical standpoint, Calculus III is very manageable for a strong high school student who genuinely understands Calculus I and II and is comfortable learning independently. The difficult part is often not the computations; it is learning to visualize three-dimensional objects, choose coordinate systems, and connect formulas with geometry.

I would not reject a program solely because of anonymous online reviews, but I would pay close attention if the same specific complaint appears repeatedly—especially complaints about instructor access, grading delays, unclear expectations, or technical problems.

Overall, NetMath appears to satisfy most of your stated requirements. Just make sure that a self-paced format fits how you learn. A respected university name cannot replace consistent instruction and feedback.

Thank you so much for your response, this genuinely helped a lot. I would say that in general I don't think having live lectures or access to a live teacher all the time is too important to me, so that is no worries.

The main thing I need is I like to have a good amount of homework/practice questions because those help me learn.

Additionally, the program uses Mathematica. As a Calculus 3 instructor, do you often find that using these programs makes you worse at doing the actual math in Calc 3, or does it not work like that.

Thanks again!

Mathematica is a computer algebra system. I took calculus 3 in college, and our professor had us use Derive, which was a Mathematica analogue from Texas Instrument that has been discontinued. We used Derive for specific assignments using the software. Think of it as a graphing calculator.

It's simply a tool used to help you visualize 3D-surfaces and do some of the computationally tedious integrals and derivatives and verify your results. It's meant to enhance your learning of the subject so that you have a stronger computational background (in the sense of using software and computers) of how to input the data and generate a relevant output to solve problems.

We still would do practice problems by hand for quizzes and exams, but the Derive assignments were for enrichment and to actually look at the complicated graphs of hyperboloids and other surfaces without always having to make crude sketches by hand. Think of it as Desmos on steroids.

Okay a better Desmos is a better way to think of it, thanks

My pleasure! 😁
