In case you aren’t aware the test also tests your knowledge of readings, differentiating kanji with the same readings, antomyns, kanji compounds, old forms of kanji, classical Japanese phrases, etc. The grade one level is only taken by the most extreme kanji otaku and and has a pass rate of only around 10%, supposedly in that 10% are many of the same people retaking the test to keep their skills fresh. You have to learn a large amount of redundant words and basically live inside a kanji dictionary for a few years to pass the test. As far as I know only two foreigners whose native language doesn’t use Chinese characters have passed grade one.
Grade two, on the other hand, is routinely taken by high school students (and many still fail) but the knowledge is within what is reasonably expected of an educated adult. Many people forget how to write some of those kanji as they get older though, especially as the prep system used by most students for the kanken is just to cram and rote memorise the less common kanji.
Pre-1 seems reasonable as well, although within the remit of someone who particularly likes kanji already.
So you basically wrote out the characters as they came up in WK? Thanks for sharing! Keep them coming 
I was exactly like you and tried to brute force my way to study it like I was studying English or some Romance language. I did RTK1 (Jalup’s Kanji Kingdom) then used ASK’s Try series – the whole series – as a dictation anki deck. Over my time studying through the JLPT levels, I turned literally all of the sentences from N5-N1 into dictation cards. Front: audio, back: sentence. I wrote sentences out using kanji and everything when prompted by the audio.
