Congrats!
I can answer those questions based on how I used to do things, i once hit level 60
Every single level here follows the same formula, you first learn radicals to learn kanji to learn vocabulary, this usually happens in two batches, once you level up you’ll have to deal with radicals and a first batch of kanji, then after guruing them you get the second batch of kanji (and the related vocabulary)
“fast” levels happen when there are so few radicals to learn you can basically unlock all the 90% kanji needed to go on in the first batch.
So, what makes things hard comes from outside, that is, if you only use wk to learn Japanese sooner or later you’ll hit a wall because it’s not enough to recall the insane amount of elements. that can be demoralizing at later levels because instead of burning items, they fall back again and again, not leaving your ever-increasing pile of reviews.
Look up the additional resources and the user scripts thread, and properly make a plan for your studies.
going fast, the average is 400-500 reviews per day.
Fairly well
But, this also depends on how diligently you studied with other resources, and when you call quits from here. It’s usual for people to get to level 60 and go to sleep, you still have tons of items to burn you know? It makes a difference between just hitting level 60 and positively burning those items
I believe someone at kitsun.io made an “infinity” set for levels 61-70 I never checked it out myself, but to keep going forward and keep practicing, immerse yourself and so on after hitting level 60 it’s something I believe it’s not talked about enough here, and it should.
As much as you are comfortable with. Normal pace is about 2 years, fastest possible is just a bit under a year
