User Reviews

Users broadly praise QuickGrader for being easy to use, fast, and flexible, with strong value for teachers and homeschooling. It’s widely used over years and seen as a reliable time-saver thanks to numerous grading options and straightforward scoring. However, recurring concerns focus on UI/UX: design changes reduce visibility of grading scales and cause orientation-related viewing issues. There is also a desire for more features, such as auto-grading and broader test-creation capabilities.

Pros

Easy to use and intuitive interface.
Saves time and makes grading faster.
Flexible grading options and customization (adjust number of questions, view by number correct, edit grade ratios).
Great for teaching and homeschooling.
Long-term reliability / long-time use on device.

Cons

UI/UX design changes hinder visibility of grading scales and cause orientation-related viewing issues (limited scale visibility, scrolling, orientation shifts).
