, many papers of which are cited in the book (Some of the research found no benefit whatsoever for rereading).

Based on the available evidence, we rate rereading as having low utility.

Even worse, repeated exposure increases our familiarity with a topic, leading to The illusion of knowing hinders us when studyingThe illusion of knowing hinders us when studying
The authors of [[Book - Make it stick.. the science of successful learning]] highlight a common problem: Students tend to confuse familiarity with mastery of a topic.
