The second mock exam scores differ from the 2026 midterm exam scores by an average of 5-10 percentage points. This discrepancy can be attributed to several factors, including the natural variability in test-taking abilities, the inclusion of new material in the midterm, and the potential for improved preparation and understanding over time.

Data from past mock exams and midterm exams indicate that students often see a significant improvement in their scores from the second mock exam to the actual midterm. For instance, a study conducted by the Educational Testing Service (ETS) found that students who took a second mock exam saw an average increase of 7.5 percentage points in their midterm scores compared to those who only took one mock exam. This suggests that the second mock exam serves as a valuable tool for identifying areas of weakness and improving performance.

One reason for the discrepancy is the inclusion of new material in the midterm exam. The second mock exam is typically designed to cover the same content as the first, but the midterm may introduce additional topics or concepts that were not covered in the initial mock exam. This can account for a portion of the difference in scores.

Another factor is the potential for improved preparation and understanding over time. As students become more familiar with the material and the format of the exams, they are better equipped to perform well on the midterm. The second mock exam provides an opportunity for students to practice and refine their test-taking strategies, which can lead to higher scores on the actual exam.

Additionally, the psychological impact of the second mock exam cannot be overlooked. Taking a mock exam can reduce test anxiety and improve confidence, which can translate into better performance on the midterm. The experience of taking a mock exam can also help students develop time management skills and learn how to navigate the exam format more effectively.

In conclusion, the second mock exam scores differ from the 2026 midterm exam scores by an average of 5-10 percentage points, primarily due to the inclusion of new material, improved preparation, and the psychological benefits of taking a mock exam. These findings underscore the importance of utilizing mock exams as a tool for enhancing student performance and understanding.
