You are correct.

I am from the French-speaking part of Switzerland, I started learning German in kindergarten (though those lessons were mostly useless until 7th grade). By 9th grade I had French, German, English and two options : Latin and Ancient Greek. (All students were required to stay from 8AM to 4PM at school, those who didn't study ancient languages just sat in a room guarded by a teacher whose task was to make sure they did not talk to each other too much).

In High School it was a bit different, you had to choose between German and Italian (Two of the four official languages) and between English and Ancient Greek (Yes, some people actually pick Ancient Greek) and an option, which spans from Math, Biology/Chemistry or Psychology to Latin, Spanish or Italian.

None of these choices actually restrict what you can study later in college.
