**Introduction:** The test grade curve calculator is a handy tool for students and educators alike. It allows you to adjust an original test grade based on a specified curve percentage, providing a fair representation of performance in comparison to a class or predefined standard.

**Formula:** The curved test grade is calculated by adding a percentage of the original grade to the original grade itself. The percentage is determined by the curve percentage entered.

**How to Use:**

- Enter the original test grade in the “Enter Original Test Grade” field.
- Enter the curve percentage in the “Enter Curve Percentage” field.
- Click the “Calculate” button to get the curved test grade.

**Example:** Suppose you scored 80 on a test, and you want to apply a 10% curve. Enter 80 in the “Enter Original Test Grade” field and 10 in the “Enter Curve Percentage” field. Click “Calculate,” and the result will show your curved test grade.

**FAQs:**

**Q: Can I use negative values for the curve percentage?**- A: No, the curve percentage must be a non-negative value.

**Q: What happens if I enter a curve percentage higher than 100%?**- A: The calculator can handle curve percentages greater than 100%, reflecting a significant curve in the test grade.

**Q: Is the curved test grade rounded to a specific decimal place?**- A: Yes, the result is rounded to two decimal places for precision.

**Q: Can I use decimal values for the original test grade?**- A: Yes, the calculator supports decimal values for the original test grade.

**Q: Is there a limit to the original test grade that can be entered?**- A: The original test grade must be between 0 and 100.

**Conclusion:** The test grade curve calculator is a useful tool for adjusting test scores based on a specified curve percentage. Whether you’re a student seeking a fair representation of your performance or an educator implementing a grading curve, this calculator simplifies the process and ensures accuracy in the curved test grade calculation.
