It varies a lot from one school to another, at mine we did “block scheduling” so you had 4, 90 minute classes a day, and different classes 1st and 2nd semester

Which had its pluses and minuses. You could definitely get a lot more instruction time in during a class that way

But for something like a language, if you’re unlucky and your schedule works out that you had it first semester one year and second the next, you’re basically going a whole year where you may not have practiced those language skills.

Other schools around me I think usually had 45 or 60 minute classes, but sometimes electives which might include language might have gotten shorter timeslots than core classes
