I’m definitely feeling the same on level 7, however I feel like the quality of the mnemonics that Wanikani is providing has definitely dropped significantly. A lot of them are words that sound similar but I more often than not am writing the words literally (not the best example but like ゆう and よう when two mnemonics refer to youth it could be either reading…) I’m hoping it’s just for this level as the first couple of levels had some brilliant mnemonics that really helped me through!
I think we just have to stick with it now and make sure there aren’t too many items in Apprentice so that you aren’t overwhelmed!
