I live in Hungary at the moment. I learn at a Uni too and my plan is to move away when I finnish it. I barely wear a Yarmulke on a street. I wear only at home. When I wore a Yarmulke on the street people looked at me like I am a UFO. My advice is to wear a hat, cap, etc..
However I have an opinion and something I saw. Once a person told to an Orthodox Rav that he is afraid at the Uni to wear a Yarmulke because anti-semites might hurt him and asked the rav if its alright to not to wear in the class and the rav said it is okay. I have seen an Israeli wearing a tzitzit on the street without a yarmulke, hat or anything. He was religious.
I wish you all the best in France! L’shana habaah b’yerushalayim! so this won’t be an issue anymore.

According to the media the US is becoming more and more like France. I have just seen a video where a professor said that you need guards to protect you when you want to speak about Israel. In Crown heights the jewish community has problems with his black neighbours. At last the muslim community is growing in the USA too. I forgot kkk and other nationalist, patriotic movements. Obiously it is better than France however there are serious issues there too according to what I saw in media.
