Doing 200 lessons at once means that you’ll get a batch of 200 reviews EVERY TIME until you start spreading those out. This can take the drive to do reviews and tell it to go jump off a bridge and drown itself until you feel “motivated”, which makes burnout more likely to happen.
Here’s an example of what I mean, with actual numbers…
This is the progress of about a month:
On October 17th, there are 22 apprentice.
Then, 150 lessons are done, and now there are 175 apprentice.
This means that I’m going to have, say, 160 reviews the next day. If you’re not oriented to these numbers, then you’re going to be super demotivated, and that’s exactly what happened here - lessons sparsely being done, and the 175 apprentice number remaining for several days.
Then, on October 27th, the genius I am decides to do an additional 50 lessons, bringing the apprentice count to 222. This means that at this point, I’ll have 222 reviews (having neglected reviews for the previous two weeks), and because it’s been two weeks since most of the lessons were done, the material is not remembered at all.
So, this creates a fun grind that you can see between October 27th and November 18th, where the apprentice number is slowly whiddled down from 222 to 75. Note that no new material is being learned, and I’m stuck where I am because I’m bombarded by many of the same reviews that don’t stick in my head because of lack of motivation because I constantly have over 100 reviews or so.
I love WaniKani’s system, and the lesson bombardment was completely my fault - hence why I’m now staying away from it. You’re free to study how you want, but in my experience, doing all lessons at once may seem satisfying for the first hour, followed by days of regret afterwords when you have many, many reviews.
(To be frank, I probably would’ve been screwed had I decided to pull this off at a later level, due to the previous item batches from previous levels)
