## 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)

计算示例

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

  1. Current score: 68% >= 60%: Pass
  2. Points earned: 68% x 500 = 340
  3. Points needed: 60% x 500 = 300
  4. Margin: 340 - 300 = 40 points above passing
