The Final Grade Calculator on your website is a tool designed to help students calculate the score they need on their final exam in order to achieve their target class grade. It takes into account the student's current grade, the desired target grade, and the weight of the final exam in the overall grade calculation.

1. Current Grade: The student’s current grade or average score in the class, typically as a percentage or letter grade. This represents the work completed before the final exam.

2. Target Class Grade: The grade the student hopes to achieve by the end of the course. This can be expressed as a percentage or letter grade.

3. Final Exam Weight: The percentage of the total class grade that the final exam contributes. This is usually provided by the instructor or syllabus (e.g., 30%, 40%, etc.).

- Score on Final Exam: The calculator calculates the score (usually in percentage) the student needs on the final exam to achieve their target class grade. 

The Final Grade Calculator uses a weighted average formula to determine the required final exam score:

- Target Grade: The grade the student wants to achieve in the class.

- Current Grade: The grade the student has achieved so far.

- Final Exam Weight: The proportion of the overall grade represented by the final exam (expressed as a decimal, e.g., 30% = 0.30).

- Current Grade = 80%

- Target Class Grade = 90%

- Final Exam Weight = 40%

The required score on the final exam can be calculated as:

So, the student would need to score 105% on the final exam to achieve their target grade of 90%.
