I’m nearly through it ! It has been pretty challenging at points - maybe because of the burns coming back, as mentioned previously, or maybe because… life. But it should be hard - you are learning a completely different language, built on completely different foundations (assuming your first language is English
)
My top tips are (learnt during the depths of my pain) -
DO NOT RUSH Who am i kidding, you’re gonna rush. but remember taking it slow and comfortable will help you retain the information better in the long run, and learning a language is a marathon, not a sprint.
DO NOT ABUSE RE-ORDER SCRIPT if you have it, fair enough use it for doing your radicals and kanji first, but then make sure you get the vocab lessons done at a steady pace through the level duration as well. Vocab is really important for enforcing the meanings and the readings. I’ve learnt this on recent levels (SHAME ON ME)
CONSUME JAPANESE IN OTHER FORMS By level 20 you will have the ability to read around 2000 vocab words !! HURRAH - but wait, does that mean you actually know 2000 words? - unlikely. Try and actually use words in context, and remembering the vocab readings will be a piece of cake. Inevitably i think if you are racing through wanikani, you will be learning more words than you could ever possibly use as a beginner - but the ones you come across in real life will be much easier to retain.
REMEMBER HOW AWESOME YOU ARE you are learning Japanese !!! you can actually read those squiggles which 3 months ago may have been incomprehensible. level 10 is already an achievement, and if you keep putting the same effort you have done to this point - you will make it all the way to ‘reality’.
PRACTICE LISTENING AND LEARN GRAMMAR you could know all the Kanji in the world, but if you can’t understand and apply the knowledge, then what was it all for.
Good luck my friend, i hope to see you on the other side. 
頑張って
