Questions regarding: Leveling Speed, Scripts and Apprentice item count

There are a lot better ways to self-study before reviews than using the WaniKani Timeline (something like BishBashBosh or the self-study quiz scripts). Personally, I think extra-reviewing your leeches (items you keep getting wrong and end up stuck in your apprentice pile) and other low apprentice items are worth it and beneficial to both your studies and mental well-being, but I wouldn’t use it for more than that. It’ll also get extremely tiring to be doing double duty for everything.

also don’t review reviews that you’re just about to do. that’s not studying, that’s last minute cramming an SRS system. do the supplement studies inbetween sessions or after a review session (go over what you got wrong a couple times, etc.)
