With the C3LLO learning environment, the C3L offers a virtual learning platform on which teachers and students can exchange information, teaching content is provided and the organisation of part-time studies is supported. In addition to traditional tools such as forums and file storage, C3LLO offers optimal support for asynchronous and synchronous group work, online assignments and simple management of examination results.

With the C3LLO app, the learning platform can now also be used on a smartphone, regardless of time and place. The app can now be downloaded for iOS devices from the App Store and for Android devices from google play.
