Time Card & Academic Calculation Principles
- Ensure unpaid meal breaks (typically 30–60 minutes) are deducted from gross clock-in and clock-out timestamps to determine net billable hours.
- Weighted GPAs assign higher point values (up to 5.0) to Advanced Placement (AP) and International Baccalaureate (IB) courses compared to standard 4.0 scales.
- Verify whether overtime pay thresholds in your jurisdiction trigger at 40 hours per calendar week or 8 hours in a single 24-hour workday.
