Formulas Used

Pass Status

passes = current_score >= passing_threshold ? 1 : 0

1 = Pass, 0 = Fail

Points Above/Below Passing

margin = points_earned - points_needed

Percentage Margin

percentage_margin = current_score - passing_threshold

How It Works

How Pass/Fail Grading Works

Pass/fail converts a percentage grade into a binary outcome.

Formula

Pass = Current Score >= Passing Threshold

Common Thresholds

  • Undergraduate: 60% (D) or 70% (C)
  • Graduate: 70% (C) or 80% (B)

    • Worked Example

    A student has a 68% with a 60% passing threshold in a 500-point course.

    current_score = 68passing_threshold = 60total_possible = 500
    1. 01Current score: 68% >= 60%: Pass
    2. 02Points earned: 68% x 500 = 340
    3. 03Points needed: 60% x 500 = 300
    4. 04Margin: 340 - 300 = 40 points above passing

    Frequently Asked Questions

    Does pass/fail affect GPA?

    In most institutions, pass/fail courses do not factor into GPA. A pass earns credit hours but no quality points.

    When should I take a class pass/fail?

    Consider pass/fail for courses outside your major that might lower your GPA, or during heavy semesters.

    Can I switch from letter grade to pass/fail?

    Most schools have a deadline a few weeks into the semester to change grading mode. Check your registrar.
