For anyone else wondering, a gymnasium is a type of school in a lot of European countries: https://en.wikipedia.org/wiki/Gymnasium_(school).

It's high school, and parent is likely from Denmark, where high school was split into language or math, although it is odd that someone from language would be admitted to a bachelor in math without taking extra classes for about a year between the two.

In germany you have the concept of specialization and you can choose different areas.
