Having arrived in Munich - what to do next?

Did I register my place of residence within one week after having arrived?

Do I have a German bank account?

Do I have proper health insurance and have I received a proof-of-coverage document?

Have I applied for a residence permit?

Have I paid the Studierendenwerk fee?

When and where do I need to register with my university – at the office responsible for matriculation or at the International Office?

Do I have all the necessary documents for matriculation?

Do I need an extended semester ticket for public transport (MVV)?

Have I registered with my departments and institutes and have perhaps received my ID?

Did I register in time for all my courses in the upcoming semester?

If not – because the deadline had already expired –, did I ask the lecturer during his office hours if it's still possible to attend?
