Calculating test scores and percentages is effortless with QuickGrader, the premier grading app designed to help teachers, professors, and everyone tasked with grading tests, quizzes, and homework.

QuickGrader is a major upgrade from the old paper grading calculators, featuring a fully customizable interface and includes all the powerful features required for the modern classroom including half point values, adjustable grade scales, adjustable decimal values, plus/minus grading, and a friendly interface that is easy on the eyes. QuickGrader also prevents the screen from automatically dimming, allowing you to focus on grading.

QuickGrader includes a powerful feature called Point Based Grading. If a test or quiz is worth a certain number of "points", simply enter the maximum point value in the settings menu and QuickGrader will recalculate the scores, providing a direct calculation of the number of points earned for the full range of the grading scale.

QuickGrader Features Include:
• Sort by the Number Missed or Number Correct
• Half Point Values
• Adjustable Grade Scale
• Plus/Minus Grading
• Pass/Fail Grading
• Point Based Grade Scaling
• Color Coded Grades
• Adjustable Score Precision
• Adjustable Grade Letters
• Adjustable Grade Colors
• Adjustable Screen Auto-Dimming

I personally recommend

This is a great grading calculator I homeschools do it definitely comes in handy. You just put in the the amount of problems and then you find how many you got wrong and it shows the % grade and the letter grade.
The best grading calculator I have found!!!!

JUST what I was looking for! You can edit the letter grade ratio, then the # of questions. My school's grading is wonky, so I almost never put letters on students papers. But this solved my problems. Thank you!

I have been using this app for years and I love it! Simple, easy to use, and mine stays on so I don’t have to keep tapping the screen.
