Τύποι Υπολογισμού
Final Grade Needed
Calculate what grade you need on a final exam/assignment to achieve your target overall grade. Enter current grade, target grade, and final weight.
Current Grade
Calculate your current grade from completed assignments. Supports both weighted and unweighted calculations.
Grade Percentage
Calculate grade percentage from points earned and points possible. Formula: (Points Earned / Points Possible) × 100.
Weighted Grade
Calculate weighted average grade from multiple assignments with different weights. Formula: Σ(Grade × Weight) / Total Weight.
Convert to Letter Grade
Convert percentage grade to letter grade using standard thresholds (A+, A, A-, B+, B, B-, C+, C, C-, D+, D, D-, F).
Key Grade Formulas
Final Grade Needed:
Final Grade = (Target - Current × (1 - Final Weight)) / Final Weight
Current Grade (Unweighted):
Grade = (Total Points Earned / Total Points Possible) × 100
Weighted Grade:
Weighted Grade = Σ(Grade × Weight) / Total Weight
Grade Percentage:
Percentage = (Points Earned / Points Possible) × 100
Letter Grade Thresholds
| Letter Grade | Percentage Range |
|---|---|
| A+ | 97-100% |
| A | 93-96% |
| A- | 90-92% |
| B+ | 87-89% |
| B | 83-86% |
| B- | 80-82% |
| C+ | 77-79% |
| C | 73-76% |
| C- | 70-72% |
| D+ | 67-69% |
| D | 63-66% |
| D- | 60-62% |
| F | 0-59% |
Σημαντικές Σημειώσεις
- All grade percentages must be between 0 and 100.
- Final weight must be between 0% and 100% (exclusive).
- Points earned cannot exceed points possible.
- For weighted grades, total weight should not exceed 100%.
- If final grade needed exceeds 100%, the target grade is not achievable.
- Current grade calculations support both weighted and unweighted assignments.
- Letter grade thresholds may vary slightly between institutions.
