Critical reading involves actively engaging with text through questioning and evaluating arguments rather than passively accepting information. It means examining multiple viewpoints, making judgments, and understanding deeper meanings and contexts. The document outlines strategies for effective critical reading such as speed reading to identify relevance, slowing down to gain depth on interesting sections, and using the SQ3R method of surveying, questioning, reading, recalling, and reviewing material. The goal is to develop flexible reading habits that improve comprehension and retention of academic information.
