Why you should try Instant Mandarin
Having studied Mandarin for a number of years, I've tried many different methods and websites. So, I consider myself well placed to make this recommendation. I find studying the HSK program through Instant Mandarin to suit me the best for a number of reasons including easy access to a variety of quality teachers; easy to use website platform for booking lessons and accessing study material and highly responsive admin support staff. In addition, their pricing structure is probably one of the most cost effective on the market. The standard lesson time is 25 minutes, but you can easily double up classes etc if you prefer longer lessons. That said I find the 25-minute sessions more than adequate, particularly when coupled with some additional private study/homework. In short, I have no hesitation in recommending Instant Mandarin to anyone considering learning Chinese.
