JLPT is the international level language proficiency test that decides the accurate Japanese-language communication proficiency of any student according to the three-preliminary language-related elements- Reading, Listening and Language Knowledge.
The JLPT creatively comprised four levels (N1, N2, N3, and N4) in which N3 is a new addition. The complexity level is pitched halfway between the old levels 3 and 2.
N2 and N1 are pretty much the same as the old level N2 and N1 exams.
Now, the JLPT comprises five levels (N1, N2, N3, N4, and N5).
