* The grading scale: A "satisfactory" grade could be a C, a B, a pass (P), or even an A, depending on the specific grading system used (e.g., letter grades, numerical scores, pass/fail).
* The individual's goals: What one person considers satisfactory might be unsatisfactory for another. Someone aiming for high honors might find a B- unsatisfactory, while someone aiming to simply pass a course might consider a C or even a D satisfactory.
* The task's difficulty: A satisfactory grade on a very challenging assignment might be lower than a satisfactory grade on an easier one.
Therefore, there's no single answer to what constitutes a satisfactory grade. It's relative and subjective.
