High School Final Grade Calculator

The High School Final Grade Calculator is an essential tool for students to compute their final course grade using quarterly grades and exam scores. By entering grades for all four quarters, midterm, and final exams, you can quickly see:

  • Average quarter and exam grades
  • Weighted contributions of quarters and exams
  • Final course grade (%)
  • Letter grade and GPA points
  • Highest and lowest quarter performance
  • Overall performance trend

This calculator helps students understand how each component contributes to their final grade and track academic progress efficiently.

How the High School Final Grade Calculator Works

The calculator uses weighted averages based on the selected weighting system:Final Grade=Weighted Quarter Average+Weighted Exam Average\text{Final Grade} = \text{Weighted Quarter Average} + \text{Weighted Exam Average}Final Grade=Weighted Quarter Average+Weighted Exam Average

Where:Weighted Quarter Average=Average of 4 Quarters×Quarter Weight100\text{Weighted Quarter Average} = \frac{\text{Average of 4 Quarters} \times \text{Quarter Weight}}{100}Weighted Quarter Average=100Average of 4 Quarters×Quarter Weight​ Weighted Exam Average=Average of Midterm and Final×Exam Weight100\text{Weighted Exam Average} = \frac{\text{Average of Midterm and Final} \times \text{Exam Weight}}{100}Weighted Exam Average=100Average of Midterm and Final×Exam Weight​

You can choose predefined weighting systems or enter custom weights.
