## Description

Grade faster with QuickGrader, a Chrome extension that computes percentages and letter grades in seconds. It includes Dark Mode, customizable grade spacing, half-point values, decimal precision, plus/minus grading, and an optional ad-free in-app purchase for an uninterrupted grading experience.

Move beyond the old slide-rule approach with Point Based Grading, automatic recalculation of scores as you enter total points, color-coded grades, adjustable grade scales and letters, and screen auto-dimming controls. Ideal for teachers and professors who need quick, accurate results.

## Review summary

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).
