We suggest you take private class if your situation is as follows:
1. irregular or unusual working hours
2. irregular work location
3. specific learning needs such as studying in Taiwan, aiming to pass an exam, Chinese used in particular fields/contexts, etc.
4. hoping to learn at your own pace
5. hoping to have full attention of the teacher
We suggest you take group class if your situation is as follows:

2. hoping to make new friends at the same time while learning Chinese
3. working hour/location matchable to class at a set time once a week
4. focusing on general daily conversations and travel topics
