Translation of riot in Spanish

So you have taken a German course in the Ghoete Institute. Well, I certainly learned something with you, and your German is already a lot better than last time. I think we really did it.
I had a few problems with my Mac. I guess I will have to buy a new one in the near future. I have already found the right product, and I will soon order it from the local hardware dealer.
I teach at the university of natural sciences. I have studied at the ETH in Zurich. At that time I started learning Spanish and I found Vocabulix. Since then I'm using it regularly with joy.
