Group Classes and 1-1 at That's Mandarin

I generally like the classes and the teacher is great (lots of history, and very patient with us!) but have a few things I would change if I could! I think personally I need more homework to ensure I keep up with studying between classes; also, the content is a mix of what's relevant and not - the hanzi studies are very important but I also want to alternate with conversational or industry-relevant vocabulary. Maybe we could also have classes with more frequency to ensure we're learning faster and with more retention.
