N2 or N1

I'm applying VERY last minute for the JLPT in Japan and literally just made the payment even though there's 9 hours to the deadline 😭 But I'm still contemplating whether I should do N2 or aim higher for N1, and I can still change the level until the deadline.

When I did the sample questions on the website for the N1, I got 12/18 correct which I think is okay, but it also comes from me just being good at tests in general, while I'm much more shaky on the grammar/vocab section. On the reading comprehension and listening section I'm pretty confident tho.

I've learnt japanese on and off since I was 13 (so for 7 years), was maybe at N3 level before going on exchange and maybe on N2 after coming home, and have been somewhat maintaining my Japanese by having Japanese friends locally and speaking/hearing the language. Since I didn't really focus on the "book study" part while I was living there my kanji game got worse, but I still got Anki, and would like to believe that I'd be able to cram it out with that + immersion during these 3 months.

Do you guys think I'd have a shot at it? Does anyone have experience with this gap themselves? Will look at the answers when I wake up
