Economically
There are many publicly funded Master and Bachelor programs, where the only costs that you will pay are the University fees. For me, studying in a public Bachelor’s in Spain (which is cheaper than a Master) cost me roughly 1.2k euros a semester, assuming I never had to repeat a subject (otherwise I had to pay 200 more euros plus the normal price for that subject) and with only the tuition fees included. Conversely, where I study now I pay slightly above 300 euros a semester that include a transport ticket for the whole Brandenburg region.
You may also find better conditions for work or research in Germany as well. To give an example, it was relatively hard for me to find C++ developer jobs in Barcelona, where as in Germany they are quite requested. The same goes for robotics and some other niche fields.
Wholistic university approach
The student deal on public transport is only one example of how the conditions for living in Germany are quite welcoming in general. Please take into account that the minimum wage is 1584 eur when looking at those. These are other factors well integrated (in Potsdam University):
- Student housing (Studentenwohnheim) can cost you as little as 210 euros. Add 5 euros per month more for internet.
- Eating at the uni cafeteria (Mensa) will usually cost you 3~5eur for a rather complete (and healthy) dish.
- Language courses (although limited) are for free for students. There are also other options in the uni to further help if you want to improve your conversational skills.
- Sports classes for 4 months (2h a week) for 20 euros.
- Extremely abundant part-time offers intended for students or minijobs
- Student bars that are voluntary-managed and have affordable prices
I write this as I am studying my master in Potsdam since 2022. I am physically studying there and my German as of now (12.2023) is still not very good. You can read on the requirements for studying in Germany in my first steps guide
