🧮 What is an EOC Score Calculator?
An EOC Score Calculator is a tool used to compute:
- Required EOC Score – based on your current grade and your target final grade.
- Final Grade – based on your current grade and the EOC test score you get.
It’s especially useful for courses where EOC exams contribute a fixed percentage to the final grade, typically 10–30% depending on the curriculum.
✅ How to Use the EOC Score Calculator
Step-by-step Instructions:
- Enter Current Grade (%):
- Input your class grade before the EOC.
- Example: If your grade is 85%, type
85.
- Enter EOC Weight (%):
- This is the percentage the EOC contributes to your final grade.
- Default is set to
20, but you can change it.
- Choose Calculation Mode:
- Mode 1: Calculate Required EOC Score
- Enter the target final grade.
- The calculator will tell you what you must score on the EOC to reach that final grade.
- Mode 2: Calculate Final Grade
- Enter the score you expect (or received) in the EOC.
- The tool will show your final overall course grade.
- Mode 1: Calculate Required EOC Score
- Click “Calculate” and view your results.
- Use the “Reset” button to clear all inputs.
🧠 Example Use Case
Example 1: Required EOC Score
- Current Grade: 80%
- EOC Weight: 20%
- Target Grade: 85%
Calculation:
- Classwork Weight = 80%
- Required EOC = (85 – (80 × 0.80)) / 0.20
- Required EOC = (85 – 64) / 0.20 = 105%
Result: Impossible (since over 100%)
Example 2: Final Grade
- Current Grade: 78%
- EOC Weight: 30%
- EOC Score: 90%
Calculation:
- Final Grade = (78 × 70%) + (90 × 30%)
- Final Grade = 54.6 + 27 = 81.6%
Result: Grade = B (color-coded in green)
