I have been using Skritter to study for the Kanji Kentei but have found that the Skritter dictionary is pretty hit-or-miss when it comes to knowing yojijukugo. For example, 悪口雑言 is recognized but I had to create an entry for 一牛鳴地; both appear on the lowest level of the Kanji Kentei.
Is there any solution besides simply praying while doing Quick Add and then creating my own definitions and readings one by one? Thank you very much.
