Rhein-Waal is a very new university, however, it is growing fast and everything is getting better day by day. If what you are looking is being a part of huge international community and a decent study programme which can get you a job, here is the right place for you. But if you are into academics and research, then you should prefer an older university.
Additionally, the new president of the university is really nice and she already made so many improvements and hopefully in a few years with the help successful graduates Rhein-Waal will be also a well-known place, especially by the industry, since this is a university of applied sciences and what we learn here prepares you really good for the working life.
