How many years do I need to be fluent in Mandarin?

For part time study, we suggest you progress by adding 300 new vocabularies each year, that’s only less than one a day! That will enable you to progress by improving one level up HSK tests each year. Of course if you have more time to invest, you can accelerate the progress much much quicker. In general, you will need like 3 years of part time study to achieve fluency.
