Canvas Grade Viewer is a free Chrome extension developed by Ethan Vazquez. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory.

This extension allows users to view their Canvas grade average per class, even when total grades are disabled. It provides a simple solution to tally up and accurately display the total grade if it has been disabled in Canvas. The extension also offers the option to click the "Add to GPA" button, which helps users organize their grades and calculate their GPA. The GPA is conveniently displayed when you click on the extension in the top right-hand corner of the Chrome browser.

It's important to note that Canvas Grade Viewer does not show any hidden grades or take them into account. It only considers graded assignments and ignores any grades that are not yet graded. With its user-friendly interface and helpful features, Canvas Grade Viewer is a valuable tool for students who want to keep track of their grades effectively.
