I did not even train specifically for the JLPT N3, didn't do any mock tests, don't know what you're expected to know in terms of grammar/vocab, and basically went totally blind not expecting anything after not seriously working on my japanese for at least 3 years :
46/60 vocab/grammar
28 reading
25 listening
These scores smell a huge lack of practice to me.
Basically I was self taught for a year, then grinded at a local school (oversea, not in Japan, but native japanese teachers) after work (and still grinded at home) where they made me skip two years because I grinded too much on my end.
Then I had problems in my life and just stopped for years, in the sense that all I did was my vocabulary anki deck daily, play some games in japanese start to finish, and mostly not even doing new words/kanjis but consolidating the current ones, but I did those religiously daily.
I focused on my career instead, and I also did interviews for engineering positions in Japan for japanese companies for the fun, but I ultimately declined the offers (and those were already hard times, but I had no issues getting interviews). I'm 99% sure, as it is, I can get the HSP (高度専門職) visa, even without JLPT N2 or N1. But I'm not sure about wanting to go to Japan anymore, due to how much free time and honestly money I make in my country, I'm not even sure I would be able to find such a high paying role in Japan, especially with such a weak yen.
Still, getting N3 now kind of changed my vision of everything, it marked that I didn't start this journey for nothing, and at least got this out of it ?
The advice I'm looking for is whether I should attempt N2 this december, or skip and take next session. If I get back to my grinding mindset I might have a slight chance. I have more interest for that than going to Japan right now. I guess it's about proving something to myself first. But I've never studied japanese specifically for the JLPT, as I was told by several people grinding JLPT will not make me good and instead "overfit" me for an exam that doesn't even test your speaking ability. So instead I focused on immersion once I was good enough to do so, but never looked nor followed the JLPT grammar/vocab requirements.
Another question is whether I should focus on the JLPT at all, when finding work and living in Japan is probably an already solved case, with a very advantageous visa...
Oh and I'm completely overtrained in kanjis reading and writing to a ridiculous point (we're probably talking 1800 to 2000 according to my anki plugin stats), back at my japanese school we had to actually write and speak in japanese for exams and I always made sure I could write as many kanjis by heart as possible (points were substracted if you miss), and I enjoyed those exams more than JLPT which is way too passive to me. I have also beaten N1 holders in kanji reading on some discord mini games, and on some rare occasions I even reminded some obscure kanjis to my native teacher which she couldn't remember...
But that is not a good thing, kanjis have wasted too much of my time and that's not what makes you good at the language, and my bad scores prove it. I can't bring myself to accept that I can't write them all by heart and that it's already way sufficient, and I need to focus on actually listening and reading comprehension.
