Easy Grader Chart
Teachers and students often use an "Easy Grader" slide chart to quickly grade papers without doing math for every single student.
How to use: Select the total number of questions on your test from the tabs (e.g., 20 or 50). The chart will show you the exact score for every number of missed questions.

What is a Curved Test Grade?
Sometimes a test is so difficult that the entire class performs poorly. In these cases, teachers may "curve" the grades to adjust the distribution. Here are the three most common methods used:
The Flat Curve
The teacher adds the same number of points to everyone's score.
The 100% Scale
The highest score in the class becomes 100%. The difference is added to everyone.
Square Root Curve
Helps lower grades more than higher grades. Formula: √Score × 10.
The Basic Formula
Calculating a test score involves a simple percentage formula. You are essentially finding out what "portion" of the test you got right compared to the whole.
Score = (Correct ÷ Total) × 100Or if counting wrong answers:
Score = ((Total - Wrong) ÷ Total) × 100Real World Example
