I passed N2, tried N1 but failed.
I joined the local Japanese study group and some of my friends are using mainingu.

It is a free Japanese learning tool which maybe suitable for you if you like japnes movie or drama. It works like anki flashcard but the content captures the phrase the character speaks.
Keep it up and don’t give up to learn. Setting a goal of achieving which Japanese level is the most important.
It will be good to see some cartoon, anime, drama with subtitles first. You may easily understand some phrases like greeting, frequent phrases used in daily life.
