40 days to test.
I think there are many people who are embarrassed to study kanji, vocabulary, grammar, reading comprehension, and listening.
Reading is difficult to learn by self-study, but it is surprisingly easy if you learn how to do it.
As the level rises, it becomes more difficult and longer.
If you want to know the knack, take a trial lesson. Of course it is free.
I will teach you as many knack as you can in a classroom lesson for one hour or 30 minutes with Skype.
