I'm an avid self-learner advocate.
I got my JLPT N2 after only one year of study and after working as an interpret in a japanese project I get my hands on the JLPT N1.
That said certification doesn't mean you're good at the language, I developped high communication skills and abilities to translate concepts from not only the language but also from the japanese culture to the local one.
I'm truly diving into languages learning and perfetionning processes as now I already speak korean too and I'm looking forward learning chinese.
I made my appearance in the famous japanese variety show waratte koraete.
Have a good day.
