bester.durchschnitt is a free Chrome add-on developed by Osi Bluber. It falls under the category of Browsers and is specifically categorized as an Add-ons & Tools subcategory. This add-on was created to make it easier for users of beste.schule to view average grades, as the platform does not display them automatically.

With bester.durchschnitt, users can view the average grades for each subject, as well as the overall average grade for the entire semester. However, it should be noted that the "Details" display format is not supported by this add-on.

It is important to mention that this add-on is not officially affiliated with beste.schule and does not have any direct contact with the platform.
