National Taiwan University - Chinese Language Division (CLD)

I had the basics after spending 3 terms (~9 months) of intensive course at NTU CLD from scratches. What I mean by basics is that I could survive and communicate with locals without using any English. I've also continue to study Chinese in two other schools, but NTU CLD is still my favorite.

+Group classes were of 7/8 people max
+Teachers were great
+Cultural activities were good and affordable
+Other campus facilities / activities / clubs accessible. Great sport fields, gym & libraries, tons of clubs (but might require a minimum of Chinese)
+Price is fair comparing with the pace of other schools. There are schools with cheaper rates per term, but the pace difference can be huge. In my case, it took me 9 months to finish 3 course books of the national program, where it would took me a year or more in another school.
+NTU is great reference on CV if you want a job in Taiwan
+Morning, Noon and Evening classes were available
+Lots of shops and canteens in and around the campus

+/-Class pace is fast. The objective was to finish a course book in 1 term. Depending on your learning ability and homework, it could be good if you can kept up with the pace, or bad if you have to repeat the class. It is up to you to repeat a class or not, but you won't progress much in higher levels without assimilating the previous courses. To me the first 2 course books were at the right pace, while I was getting a bit behind while studying book 3.
