Master of Science / Université Grenoble Alpes
I spent my two Erasmus semesters in the French Prealps at UGA in mountainous Grenoble.
I chose Grenoble for my year abroad because I had a lot of fun attending language courses during my bachelor's degree. Now I wanted to try out the language skills I had acquired. As a big nature and sports fan, it was very easy for me to choose between Grenoble and Paris. Grenoble also has many different research institutes and is therefore ideal for a research internship.
As a Master student in medical physics, the choice of courses is unfortunately very limited, especially if you don't speak French. In my first semester, I only took medical physics courses, which were only taught in French. In the second semester (summer), there are unfortunately hardly any medical physics subjects offered, so I took more technical modules.
Purely English Master degree programs are Soft Matter and Biophysics and Nanophysics. As an Erasmus student you are not tied to a fixed degree program and can choose freely between the subjects of the Faculty of Physics (Phitem) + 1 subject from another institute. The modules in France are generally very small (3 or 6 credits), so a wide range of subjects are covered, but unfortunately often do not go into any details.
I would strongly recommend to apply for a research internship in the summer. It is part of the degree program (6 credits) and is financially remunerated (unfortunately only 4-5 euros per hour). I would apply early, at the beginning of the summer semester. I was lucky and ended up at the ESRF, Europe's largest synchrotron, where I spent two and a half months researching AI imaging. The neighboring beamline was even headed by a Dortmund native who started at the Delta!
In conclusion, I can only recommend a stay abroad in France to anyone! I learned a lot, especially during my research internship, and made some contacts that will help me with my Master thesis.
