Here’s how I’ve been doing it, though I’d recommend taking your time, like a level a week unless you can handle the heat! 
Heat being 300-400 reviews, and ~35/70 lessons a day.
Day 0 (Level up): Do Radicals + Kanji
Day +1: Do 1/3 of Vocab
Day +2: Do 1/3 of Vocab
Day +3: Do 1/3 of Vocab… Level up!
I pre-studied for level 58/59 because I had the time
