Hi folks,
I have done my WaniKani reviews and lessons. I finally remembered the differences between 上がる, 上げる, 下がる, 下げる. Those are easier to remember as が is always active (raise, lower) and げ is passive (rise, fall).
I have also checked up on some class lessons starting in March. They are all Level A1 and use Marugoto starting between lesson 7 and 12.
