A few weeks is definitely BS, but I took 3 years of German in high school and after roughly 3 months of 30min-1hr daily Duolingo I was already past the high school material.

I mean in our high school (Poland) it was like maybe 1 lesson (45mins) per week shared with a group. And of course excluding all the holidays and what not. That's not a high bar.

To be fair, you already had the high school material and you spent at least as much time on Duolingo as in the classroom.

Styles are different oo. I would say my high school was a lot more focused on writing, translation, and grammar than anything truly conversational though they did work on on pronunciation to some extent.
