My teenage daughter is not actually studying at SFL, but the teacher comes to our house every week for her Chinese class. I can agree with what others have written here - she is always very well prepared and makes good use of powerpoint etc. She speaks good putonghua and explains everything very clearly, so she is easy to understand. My daughter is taking a UK Chinese exam soon, and even though the teacher had not taught for that exam before, she has done a great job preparing my daughter. She took note of everything required in the exam syllabus and listened to all my requests for things to cover. We can definitely recommend her for anyone who needs their own personal study programme - I'm sure this teacher will do a great job of meeting your requirements.
