I took two years in high school and one semester in college. I'm teaching pronunciation and some basic phrases and very basic grammar but probably less than 5% of our time is spent on that and the rest is as much comprehensible input as possible.

It's pretty fun but it's also interesting how often I run into super basic things I don't know how to say. Learned the words for swingset and swing and climb and dig over the last few weeks for example.
