Grab the latest bookmarklet from here
Drag the link from the site given above to your bookmarks bar to save this bookmarklet. If you don't see your bookmarks bar, try Ctrl+Shift+B. Once on the IMS Student Grade Details page, click the bookmarklet you just saved, and Voila!, a shiny new version of IMS appears (okay it's not as glorious as I make it sound, but atleast it's much more functional eh).
A bookmarklet is a small script that runs straight from the bookmarks bar, when you click on it. This bookmarklet extends the functionality of the IIT Gandhinagar Institute Management System (IMS).
Disclaimer: The grades you edit are only hypothetical, editing you grades won't change them in real life.
This bookmarklet, modifies the IIT Gandhinagar IMS "Student Grade Details" page, by adding a "Calculate CPI" button. It also allows you to edit your grades for you to analyze how much you would have scored under different scenarios.
This is an independent project, and is not affiliated with the IMS or IIT Gandhinagar in any way.
