Does it really work?

I signed up for the premium subscription, but I’m debating if I want to keep it. I’m kinda bored watching the videos (I have adhd). I’m watching the beginner videos, but idk if I should switch to a different level, maybe that would help? My partners first language is Spanish, so while I’m learning new things here and there at level 1, I also know a lot of what is being said in the videos as well. I guess I am apprehensive if it really works and to keep spending money on it.
