About Grade Calculation

The Grade Calculator determines the percentage score and assigns a letter grade based on standard academic grading scales. It’s a useful tool for students and educators to quickly estimate grades.

•How It Works

–Percentage = (Marks Obtained / Total Marks) × 100
–Letter grades are based on common grading systems (A–F)
–Rounded to two decimal places for precision

•Customization Options

You can adjust the calculator’s appearance using these CSS variables:

--uch-accent: Accent color
--uch-bg: Background color
--uch-text: Text color
