Grading Policy

  • Accuracy: The primary factor in grading homework is the correctness of the answers or solutions provided. Each question or task is evaluated based on its accuracy and alignment with the given requirements.

  • Completion: The extent to which the homework assignment is fully completed can also impact the grading. Incomplete or partially attempted assignments may receive a lower grade compared to those that are fully finished.

  • Effort and Improvement: In certain cases, instructors may consider the effort put into the assignment or the improvement shown by the student over time. This can be reflected in the grading to acknowledge dedication and progress.

  • Originality and Critical Thinking: Assignments that demonstrate original ideas, creativity, and critical thinking may receive higher grades. This is particularly relevant for open-ended or subjective questions where multiple approaches or interpretations are possible.
