All bachelor programs consist of modules but not all of them have "Modulangebote" such as the 30-credit-Modulangebot in Latin American Studies which also consist of modules. Those Modulangebote are an addition to the core subject you study. There are two different options: Kombi-Bachelor (60 credits through a second subject) or two additional minors of each 30 credits. They might differ in structure and exam types from your core subject.
Students with a German university entrance qualification apply online. You can find the application form and more details on the Freie Universität's main page about study programs.
Students who hold a school degree from abroad have to apply via uni-assist.
This offer can be combined with a core subject, another 30-credit Modulangebot and the ABV-offer (general professional preparation) when studying a combined bachlor program (Kombi-Bachelor). It is recommendable for students studying Social and Cultural Anthropology and Spanish Philology with Latin American Studies.
Here you can find an overview on the different possible combinations for this module offer: Kombitabelle.
