As listed in the appendix of the examination regulations (Link), it is generally possible to choose modules with a maximum scope of 20 CP as "additional modules". This means that successfully completed modules are listed on the transcript after graduation, but the grades are not included in the calculation of the overall final grade. The examination office must be informed via e-mail about the participation in an examination as part of such an additional module prior to examination registration via Porta. As soon as the examination office confirms the assignment of the examination as an additional module, participation in this context is possible. Note: Once an examination has been taken in another module, it cannot be subsequently converted into an additional module.
