I have reached level 3 two days ago. Obviously it takes a little while to reach the level 4 (even when all my reviews are 90%+).
I have decided to continue using Wanikani, but I don’t want to waste my last few days of free trial.
Should I wait until 90% of my items are in Guru (that’s when the next level unlocks, right?), or should I subscribe now in order to progress properly?
