I signed up for a Japanese Language Proficiency Test (JLPT N4) in December! It's been a good motivation to put more time into learning vocabulary and grammar!
I found a neat resource to practice reading: Tadoku, a collection of ~100 free picture books of varying difficulty, released under Creative Commons licenses (BY-NC-ND), some with audio!
Especially the lower-level books are really motivating, because I can actually read them without a dictionary!
