Common GRE mistakes include poor time management, lack of familiarity with the test format, and overthinking questions. Many students struggle with pacing, especially on the verbal reasoning and quantitative reasoning sections, leading to rushed answers or leaving questions unanswered. Another mistake is focusing too much on difficult questions and neglecting easier ones, which can waste valuable time. Not practicing enough under timed conditions also leads to anxiety during the actual test. Additionally, misinterpreting questions or failing to read instructions carefully can result in simple errors. Students also often neglect the analytical writing section, underestimating its importance, which can hurt their overall score. Lastly, ignoring the importance of vocabulary and grammar in the verbal section, especially for text completion and sentence equivalence, is another common pitfall. To avoid these mistakes, consistent practice, familiarization with the test structure, and strategic time management are key.
