It’s Kumirei-senpai’s script. Scripts are not actually made by wanikani, but by some of the users in the community. They’re safe to use, and many are very helpful (at least in my opinion and experience)
There’s even a post with many of them compiled, here:
(Note: Just mentioning that I use just a couple of them, not every one on the list )
that’s a lotta forgotten items. But that’s 49 items that haven’t been forgotten.
edit the second: got it down to 500 reviews.
this number probably going to go to 550 or so the next time I do reviews, but it might be a better idea for me to ease into reviews again over time. Better to do 100 reviews a day for 5 days than to be angry at myself for another week.
When I get unmotivated I usually do a couple dozen,sometimes up to a hundred/twohundred at a time, and leave it again. At some point I will get the motivation to do all at once. Last time though, what really helped me, was installing the SRS Reorder Script. This way I could get the burn items out of the way, while not having the apprentice items coming back all the time (the way I see it, they’re of timer anyway, so was always going to fail a bunch). This got me through the pile right quick (~600 at the most) as I wasn’t failing as much, about 60-70%, being more motivated as a result.
(You do need to tinker the settings in the script a little bit, see script comment section)
