Reviews log all the correct and incorrect answers provided through the 'Reviews' section of WaniKani. Review records are created when a user answers all the parts of a subject correctly once; some subjects have both meaning or reading parts, and some only have one or the other. Note that reviews are not created for the quizzes in lessons.
