It didn’t need to be asked, but I don’t mind answering anyway
There is a difference in the difficulty of each podcast within each level, as you’ll find once you start digging in. Some of the intermediate lessons are closer to upper-intermediate while some are closer to pre-intermediate / beginner.
So why don’t I just pipe down and listen to upper-intermediate lessons? I like to listen to podcasts while I walk to and from work every day. Because I can’t keep my full focus on the podcast (I have to look both ways before I cross the street, etc.) my listening comprehension isn’t as good as it is when I’m listening at home, or some other place where I can focus completely.
I can and will listen to the upper-intermediate podcasts, but the intermediate level podcasts hit the sweet spot for me: just hard enough to challenge me without distracting me too much from my surroundings while walking around.
Thanks for the suggestion. Hope you enjoy the content you find here, and I hope that new content is on the way!
