Speed/Ease of completion - SL vs SDC vs Penn Foster

[Merlin]

Keep in mind that you are able to revise your Study.com papers as much as you like (at least 3 times anyway) based on feedback from the grader, so getting an A (93% or better) on every paper is easy if you keep revising until you get to the grade you want.

I completed 20 courses with SDC and earned an average of 97% in those classes; most of my papers came in at 95% or higher. I had trouble with some of the first courses I took with SDC (writing courses) and found that I needed to resubmit them after feedback to score well. I felt like the graders were being inconsistent and not following what was asked. However, that was not the case.

Basically, the graders are looking at the rubric as the only measure of what good looks like, so if you follow the rubric exactly, you will usually score high. Early on I was using my own interpretation of what good looks like, but this resulted in a lower score. Once I started following the rubric to the letter and learning how the graders did their thing, I found more consistency with the grading and a higher overall score on each paper.

That is my experience anyway.
