Which method is least effective for preparation for the exam?

The method that is least effective for preparation for the exam is ignoring practice questions entirely. Practice questions are an essential component of exam preparation as they help the learner understand the format of the exam, identify areas of weakness, and reinforce knowledge through active recall. By neglecting practice questions, a student misses out on valuable opportunities to apply what they have learned in a manner that closely resembles the actual exam conditions. This can lead to a lack of familiarity with the exam's structure, content, and typical question formats, which can ultimately decrease confidence and performance on the day of the test.

In contrast, studying in groups, reading over notes, and engaging in discussions all provide avenues for deeper understanding and retention of the material, making those methods more effective. Each of these approaches encourages active engagement with the material, whether through collaboration, repetition, or conversation, and can significantly enhance one's preparedness for the exam.
