This extension shows grade averages hidden by Librus Synergia
This extension allows you to show the average on Librus Synergia's website. Some schools decide to hide the average from you, that's when this extension comes in. It is highly customizable when it comes to calculations. The extension is fully open source and you can check it out on GitHub: https://github.com/librus-stats/librus-average.
DISCLAIMER: This extension uses Google Analytics to log simple events (preference changes and extension load). None of your personal data (grades or average) is being logged or used in manners other that displaying it.
