1) I was in a Mandarin dual language program in elementary school and took classes in middle school, as well as an online class my first year of high school. I haven't practiced in the three years since, because none of my family speaks Chinese at home. My best friend does, though, so she might be a good person to practice with!
2) My goal is mainly to review the Chinese I learned a long time ago and get back in the habit of actually using it. I want to focus on grammar and vocabulary when I'm writing/speaking, since I think those are the pieces I've lost the most. I also plan to pay extra attention to tones, especially for new vocab.
