For the majority of this session (until the last couple exercises), the program was using the accusative case with "mit". My understanding is that you only use the dative case with "mit". Am I missing something here?
You always need to use the dative case after MIT, so I'm surprised you found it with an accusative case...please could you send us the level and session number where this happened so that we can make sure there is no bug about this? I've tried to spot errors of the type, but haven't seen anything so far.. Thanks in advance and enjoy the program!
