Online and onsite blended course experience

I tried to learn Chinese with a private teacher and After 4 months I gave up because I could not see real improvement and got desperate. 4 years later I came across a very funny and creative video about chinese language. I found out that the video was created by a chinese language school (Silk Mandarin) in Shanghai and I watched more of their videos. After watching some of the videos, I got motivated and decided to give chinese a second try! I started from the beginning, HSK 1 Blended course which is amazing for people with tight schedules. Because each student studied the lesson before class on our own time and during the online class we just practiced and reviewed if we had some questions. Silk Mandarin was very flexible and helped me finding a class that fitted my schedule perfectly. This course was great to remind myself what I learned before and practice my pronunciation during the class. After I completed the HSK1 course I decided to continue with HSK2 but I told Silk Mandarin that I wanted a different type of blended course. Once again they were very flexible and helpful. They offered me a Blended Course with onsite class instead of online. Online Blended course was a good start but onsite class is better for further levels like HSK2. I think the communication between teacher and student flows better and it really makes a difference to improve pronunciation.
