Old thread but for what it's worth, I did Elementary Putonghua I five years ago; it was OK but I had little interest back then so I completed the course and stopped.

I am now looking for a full time course, either 6 or 12 months.

Has anybody done or know someone who did CUHK's 6/12 months full time course?
