4上 to 下
Finally finished Hsk-4上. Took me six months. That's a bit slow but I'm simultaneously studying the Chinese Made Easier 4 book and almost halfway through that as well. The CME and Hsk series have a different focus, but also overlap in many places. Tomorrow I will break the seal on the 4下 book. I definitely feel it's getting harder, but not overly difficult, so I think Im at my sweet spot.
