Which factor has the most significant effect on test performance?

Your mastery of course content is indeed the most significant factor affecting test performance. This is because a deep understanding of the material allows you to accurately recall information, apply concepts, and analyze questions during the exam. When you have a solid grasp of the subject matter, you’re more likely to interpret questions correctly and formulate appropriate responses, leading to higher scores.

While understanding the exam format, effective time management, and maintaining calmness are all important aspects of test-taking, they primarily serve as supporting skills that enhance your performance. For instance, knowing the format helps reduce anxiety related to the structure of the test, effective time management ensures you can complete all questions in the allotted time, and feeling calm allows you to think more clearly. However, without a well-developed knowledge base, these skills may not significantly impact your overall performance. The foundational element of test success lies in your command of the content being assessed.
