WWU has a pretty math heavy curriculum (although there are now less rigouros math courses for Informatikstudenten) and you will learn a lot of abstract thinking, computational theory, optimizations, operating systems, databases (with theoretical foundations), computer graphics, computer vision, machine learning and you can get a glimpse into things like Medizinische Informatik in seminars.

Take a look at the course list, pick one that sound interesting and just go there for a day or two in a big hörsaal, no one will care about you. Vorlesungen are boring but it will give you insights on the topics you will study there.

In most courses no one will care whether you go there or not, just do it at home and quicker.

You won‘t need all of that but it will give you a strong foundation for whatever the future holds.

If you want to work look for part time positions and study on the side. It‘s easy because the cost is only €600/year and includes public transport.

The degree will help you everywhere: immigration, getting past hr, getting jobs that go beyond web dev etc.
