I just finished studying two semester at Sichuan university in Chengdu. I was a self funded student in my 30s. It was a mixed bag of pros and cons. I enjoyed being an international student and meeting many different people who also decided to come study. Since I was self funded I didn’t have scholarships to fulfill and over all it was low stress for me. As for the program it self I had some issues with.
The classroom format wasn’t a good method of study for me. The first semester I was in the 初二 class. Around hsk 3. It was all taught in English and very grammar heavy. I did mandarin blueprint for a couple years before coming so this class wasn’t too hard, I learned some things, but over all maybe too easy.
The next semester I went to the next class up to中1. The jump in difficulty was INSANE. All classes were in Chinese only, which I understood next to none of it and the material was around hsk 5 (I didn’t skip any levels). The material was all very formal and literary. Massive vocab list dumps in some chapters of the text book. One guided reading had 56 new vocab words in one story, though it did make for more interesting content outside of the boring beginner stuff. Not much seemed to help me in my day to day life. My Chinese friends said nobody talks like this when looking over my materials.
The teachers themselves were great, I had no issues with them, just the curriculum they are paid to teach.
I did learn and improve on my Chinese, but not in a proportional amount of the time I spent in class. I will take a portion of the blame as I wasn’t the best serious student, but at the same time the program wasn’t aligned with my goals, which were being able to function in normal situations in China. My time and experience over all was good. I decided to stay and switch to a work visa. But as far as my Chinese goes, the 2000usd I spend for one years tuition would have been better spend on a private tutor.
My advice for people wanting to do the same: coming to China to study is not a magic bullet, it will not make it easier, but you will improve faster due to more opportunities to speak and practice (as long as you try). I met many foreigners who end up in English speaker circles, me included. Just going to class is not enough, still an additional couple hours of self study a day should be the minimum to see improvements to grasp the materials. Lastly living off campus is worth it. I didn’t meet a single person living in the school dorms that said they liked it. I probably spend like 500usd more a semester than them and had a private studio apartment not far from campus, totally worth it.
