German in Boarding Schools

While I have everyone’s attention, so to speak, how realistic is it for a student to take 2 language classes at some point in boarding school after freshman year (for either 1 year or 2). Is this common? An “extra” course? Enough flexibility in electives after freshman year?

Trying to figure out how meaningful the existence of German or Arabic would be for the kid.

In the “German school scenario,” he would need to take 3 years of French (4 if he wants to) and 1 year of German (2 would be better). Let’s call it 5 years of language total.

In the “Arabic school scenario,” he would be starting Arabic from scratch: 4 years of Arabic would be essential. But then he would still need 2 years of French. Let’s call it 6 years of language total.

In the “forget it, boarding schools don’t have great language offerings but all have French scenario,” he would basically need 3 years of French. Rather than waste a 4th year taking a “useless” course like Spanish 1 (kidding - mostly), he could do then do other things.

He likes to draw and is very good at it, so might become kind of a fine arts type.

He plays an instrument and is no virtuoso or anything, but not bad so might be in an orchestra or ensemble.

Let’s assume he wants to pursue 1 of the 2 art/music possibilities. Is the Arabic scenario out? The German?
