i took Japanese classes for 4 years as an elective in my school and am at least N4
but because our textbooks aren’t based on jlpt, it’s kind of hard to figure what i know and what i don’t. i am missing some stuff from N4 probably but i probably have stuff found in N3 as a result. so like i have no idea how to start filling in the gaps with large amounts of n3 grammar and vocabulary
