No I just wrote whatever characters we were studying in class that week over and over while I watched streams of Chinese TV. I watched with Chinese subtitles but I didn't actually try to understand every word. It was mostly about framing my mindset towards a Chinese style of speaking and writing.

I spent maybe an hour or two a day, a few days a week. That was my most productive study method for calligraphy and pronunciation. Grammar and other subjects had to be studied in separate ways, but keeping the Chinese tv stream on helped either way.
