Letters of Recommendation for Distance Calculus Students

An academic letter of recommendation is a letter, typically written by an instructor or professor, about a student and for a student. It is shared either directly with the student or (more often) sent confidentially at the student's request to a college, university, graduate program, or employer.

Why Letters Vary So Much in Quality

Letters of recommendation range enormously in depth and usefulness. On the low end, an overburdened instructor may write something generic:

TO WHOM IT MAY CONCERN:

Ms. Jones was a student in my Differential Equations course. She earned an A-. She completed all of her homework on time.

On the high end, when the instructor has had genuine, sustained interaction with the student, seen exceptional work, watched the student grow over the course of the term, and observed specific moments of insight or perseverance, the letter can be substantially richer and more credible to admissions committees.

Both undergraduate and graduate school applicants now routinely need multiple letters of recommendation from prior teachers, instructors, or professors. Letters are also standard fare for many employment applications.

The Lecture-Hall Problem

A student who takes Calculus in a 200- or 500-seat lecture hall faces a real difficulty when it comes time to ask for a recommendation: the lecturer may not actually know them. Many students in that situation visit office hours weekly precisely to build enough relationship that a meaningful letter is even possible at the end of the term.

Why Distance Calculus Is Different

The pedagogical format of Distance Calculus is built around intensive student-instructor interaction. The recursive back-and-forth on every assignment is, in effect, a continuous office-hours conversation - sustained over weeks or months, on real mathematical work that the professor has seen the student think through in detail.

Add to that the multiple evaluation tools - mastery-graded recursive homework, take-home final exams, the proctored final exam, and the final video portfolio - and the head professor, Dr. Robert Curtis, has an unusually rich set of evidence to draw on when writing a letter. The result is letters that contain specific, concrete observations about the student's work, not generic boilerplate.

Who Can Request a Letter

Distance Calculus has a healthy spread of grades - A's, B's, and C's all appear in completed courses. Earning a B or even a C does not automatically preclude a positive letter. On request, Dr. Curtis will review your gradebook and course conversation transcripts and tell you honestly whether he can write a strong letter for you.

Students who earn solid A grades are in the strongest position for a favorable letter.

Letter of Recommendation Interview (Optional)

Students who request it can schedule an optional Letter of Recommendation Interview after the course concludes. In that conversation, the professor and student discuss the student's academic goals, the points the student would like emphasized, and the specific undergraduate/graduate programs where the letter will be sent. This produces a letter that is genuinely tuned to the student's intended next step.

How and When to Ask

If earning a letter of recommendation is part of your academic goal set, reach out to Dr. Curtis early: ideally near the beginning of the course (so the professor knows your goals from the start) and again near the end. The earlier the conversation begins, the more concrete material there is to draw on when the letter is written.

A lifesaver. When I found out I needed a course done in the last weeks of summer I thought there was no way i'd find one available, but this let me complete the course as quickly as I needed to while still mastering the topics. Professor always got back to me very quickly and got my assignments back to me the next day or day of. Can't recommend this course enough for students in a hurry or who just want to learn at their own pace.

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.

I found out from my MBA program that I needed to finish calculus before starting the MBA. They told me 3 weeks before term started! I was able to finish Applied Calculus from Distance Calculus. Definitely a great class. Thanks Distance Calculus!

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.

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.

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.
