I broke down and got the ignore answers script because of things like this. I make a lot of typos and eventually being marked wrong because I typed “Un” instead of “Uni” was the final straw 
The script is surprisingly easy to use as intended (rather than abuse, which I was worried I might be tempted to do). I guess it’s different when your goal is learning rather than getting through a class or something. [OBSOLETE] Wanikani Override ("ignore answer button")
