First you need to create an online application for the desired field of study, select yes under the item "Registration for the language test" and submit it

In the application portal of Freie Universität Berlin you will find the tab "Information for subjects with language test" on the right side of the screen. At the end you will find the button "Register for the language test". Use this to register in the test registration portal via Navigation → Your registrations or to deregister for the required language test. Please note that there may be multiple dates per language to choose from, but you can only select one date per language.

If you have applied for more than one philology (e.g. English Philology and French Philology), a separate language test registration is required per language. After completing the registration, you will receive a confirmation email.
