That's Mandarin
I have used That's Mandarin for almost 1 year, and I have really enjoyed the experience. It has a structured curriculum with audio and visual aids to help learn new vocabulary, as well as supplementary learning exercises to help consolidate your learnings. The platform is easy and intuitive to use as well. My teacher Wu Laoshi in particular has been knowledgeable, friendly and makes our lessons both an enjoyable and fruitful time. She is always patient and enthusiastic in answering questions and often comes up with helpful ways for me to remember certain vocabulary and phrases. She is always flexible as well, as I often cannot commit to a regular lesson time, and I appreciate this flexibility greatly. I would recommend this experience to anyone looking to expand their Mandarin skills, especially for an online platform.
