Training is good, not boring, with listening, reading, writing, speaking parts

I've completed HSK3 class.
Of course it will not give 100% understanding of all required words & grammar for freely communicate, but its like one of steps , which need to do to the success of mastering language.

This training is not an easy walk, as other trainings, it requires to work by learning new words, expressions, grammar, do writing, reading, listening exercises. Compared to other trainings, which I've completed before, this one has balance between all these language part without focus only on one part (e.g. many books / trainings only give expressions and new words without any note about grammar rules).
