Grades

With the Distance Calculus course pedagogy (teaching strategy) based upon Mastery Learning, the concept of grades calculated with point accumulation is not applicable: all of the student's homework is expected to be completed at 100% correct, so getting anything less than an "A" on your homework is not possible.

Accordingly, to base a student's grade (solely) on a proctored, written final exam, is not a realistic and fair assessment of the student's gained knowledge in the course.


Therefore, we have devised the following combination of different evaluations to fairly and accurately determine an earned grade in a Distance Calculus course.

The options for the "C" Grade are intended to accommodate the student who needs to finish the course quickly, and the final grade is of less importance than completing the course post haste.

The 48-hour Take-Home exams are completed independently by the student, under the honor system, with the use of the computer algebra software. These Take-Home exams are a bit more challenging, usually 8-10 questions each, meant to be completed in 2-3 hours student work time, and are not graded recursively. The 48-hour time period is provided to accommodate students with work/family/life schedules that are not necessisarily predictable (i.e. the take-home exams don't take 48 hours to complete!) A very high percentage of students who finish a Distance Calculus course earn an "A" grade; the take-home exams are meant to measure the student's knowledge upon completion of the course, rather than "lower the curve" as they say.

The proctored, written final exam is the same for all three grade levels, and completed without the use of computer algebra software or other notes or aides. This proctored final exam is conducted at the student's location via Skype video call with the instructor, or, alternatively under the supervision of a proctor pre-approved by the instructor. Final Exam proctors are proposed by the student, and must be one of the following:

  • a Librarian at a local library (public, or school/college/university), or
  • a Teacher at a local school/college/university, or
  • an Official at a place of worship (church, temple, mosque, et al.)
[Note: Final Exam proctors at your location are usually very easy to identify and get approved - don't worry about this until you near the completion of your course work.] The proctored final exam is completed within a 2 hour time limit; as our completing students are exceptionally well-prepared, the vast majority of completing students report that the proctored final exam "was easier than I thought it would be."

The Final Video Portfolio is a set of screen videos that the student makes answering a set of questions posed as part of the final exam process. It is similar to "come to the board and complete this problem" as you might be asked to do in a classroom course. Final Video Portfolios are generally 5-10 questions to complete in video format.

C "C" Grade - Either Path Below
Path 1 - Full Coursework
  • Complete all course assignments at 100% correct (recursively graded)
  • Complete Final Video Portfolio (5+ problems)
  • Score 60% or higher on the proctored written final exam
OR
Path 2 - "C Path" Core Subset
  • Complete the "C Path" subset of core assignments at 100% correct (recursively graded)
  • Complete Final Video Portfolio (5+ problems)
  • Score 70% or higher on the proctored written final exam
B "B" Grade
  • Complete all course assignments at 100% correct (recursively graded)
  • Complete the 48-hour "B-Level" Take-Home Final Exam at 70% or higher
  • Complete Final Video Portfolio (7+ problems)
  • Score 70% or higher on the proctored written final exam
A "A" Grade
  • Complete all course assignments at 100% correct (recursively graded)
  • Complete the 48-hour "B-Level" Take-Home Final Exam at 80% or higher
  • Complete the 48-hour "A-Level" Take-Home Final Exam at 80% or higher
  • Complete Final Video Portfolio (10+ problems)
  • Score 70% or higher on the proctored written final exam

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.

Awesome classes! I was really weak with Calculus, so I retook Calc 1 and kept going into Calc 2. I feel like I finally understood Calculus. The finals were pretty thorough, but not nearly as stressful as the blue book exams. I highly recommend these courses!

The course was intense and required a lot of hard work. Professors ready available to assist when needed. Professors presented and explained materials/course work in detail and provided explanations and resources.

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.

As a full-time business owner completing an Executive MBA, I needed to satisfy a calculus prerequisite without putting my work on hold. Distance Calculus made that possible. The fully self-paced structure let me work early mornings and weekends around an unpredictable schedule, which a fixed-semester classroom course never would have allowed.
The course covered the core business calculus material thoroughly — derivatives, optimization, integration techniques including u-substitution, the Fundamental Theorem of Calculus, improper integrals, and numerical methods. The LiveMath computer algebra environment was central to the experience: it forced me to build each step explicitly rather than just arriving at an answer, which actually deepened my understanding of the mechanics.
Communication through the student portal was responsive when I had questions. For working professionals who need a rigorous, accredited calculus course on a flexible timeline, I'd recommend it.
