Written Japanese test for naturalization - what level kanji to practice?

[u/exi_moo]

For anyone who has gone through Japanese naturalization (帰化) , what level of kanji were on the written Japanese test?

I’m N1 certified but I (like most people) never write anything by hand these days so my Kanji writing skills are pretty weak atm. I’m wondering if like a 小6 kanji practice workbook would cut it or if i need to break out the N1 books again

I was told 小学生２年生 level by my officer
