Even if i used Ru-Kr courses many years ago to typing practice, it alredy had a lot of mistakes. When you do a translation please DO NOT use Google translation.
As everybody know how does it (google) make a translation … if you do not know… for example from courses “얼마나 오래” is “long time? long” can guess it had to be “how long time” but… ok Google.
In every lesson it have at least one mistake. And it’s 7 lvls…
Really disappointed of not professionalism. why people should pay for mistakes?
