I highly recommend NSC

My wife and I began looking for a summer program for our 16 year old son who already had taken a year of Mandarin in the US, and we selected NSC. Our son wanted an intensive language course, and the university in which he was enrolled seemed to be the best choice. Other leading programs had teachers which they hired and did not teach at a university. NSC provided additional tutorial time at a very reasonable price. So, in addition to learning in a classroom environment, our son was able to travel around the city and speak the language in everyday situations. I strongly recommend NSC.
