Like other users, I found a “steep jump” from intermediate to upper intermediate, even when I start with the first lessons in each category (curriculum, grammar, HSK 5, etc.). I can’t find bridge lessons from intermediate to upper intermediate. A search for “bridge” within intermediate, for example, returns only two or three lessons. I did see a blog post for this from two years ago and I wonder if this has been addressed more recently.
