Question

Make 21 grades highest grade 900

Answer 1

To create a grading system where the highest grade is 900, we can divide the total score into 21 grades, ranging from the lowest to the highest. Here’s one way to set it up:

1. **Total Grades**: 21
2. **Highest Grade**: 900
3. **Grade Intervals**: Divide the total score by the number of grades minus one (20, since a grade range is formed between consecutive grades).

### Grade Distribution:
- **Grade 1**: 0 - 40 (40 points)
- **Grade 2**: 41 - 80 (40 points)
- **Grade 3**: 81 - 120 (40 points)
- **Grade 4**: 121 - 160 (40 points)
- **Grade 5**: 161 - 200 (40 points)
- **Grade 6**: 201 - 240 (40 points)
- **Grade 7**: 241 - 280 (40 points)
- **Grade 8**: 281 - 320 (40 points)
- **Grade 9**: 321 - 360 (40 points)
- **Grade 10**: 361 - 400 (40 points)
- **Grade 11**: 401 - 440 (40 points)
- **Grade 12**: 441 - 480 (40 points)
- **Grade 13**: 481 - 520 (40 points)
- **Grade 14**: 521 - 560 (40 points)
- **Grade 15**: 561 - 600 (40 points)
- **Grade 16**: 601 - 640 (40 points)
- **Grade 17**: 641 - 680 (40 points)
- **Grade 18**: 681 - 720 (40 points)
- **Grade 19**: 721 - 760 (40 points)
- **Grade 20**: 761 - 800 (40 points)
- **Grade 21**: 801 - 900 (100 points)

### Summary:
- Each of the first 20 grades has a range of 40 points.
- The 21st grade has a range of 100 points, allowing for a higher ceiling to reach the maximum score of 900.

This system allows for clear distinctions between each grade, providing a straightforward metric for evaluation.
