Shida High School exams typically have a duration of 90 minutes per subject. This standardized time frame is designed to ensure that students have ample time to complete their tests while also maintaining a consistent structure across all subjects. The duration is based on research that suggests this length allows for thorough assessment without overwhelming students, balancing the need for accuracy with the time constraints of a school day.

The 90-minute exam duration at Shida High School is influenced by several factors. Firstly, it aligns with the typical time allocated for classroom instruction, which helps maintain a seamless transition between learning and assessment. Secondly, research indicates that this duration is optimal for cognitive processing, allowing students to engage with the material without experiencing fatigue. According to a study published in the Journal of Educational Psychology, a 90-minute test period is conducive to maintaining students' attention and performance levels.

Additionally, the standardized duration helps in the efficient administration of exams. It allows for simultaneous testing across different subjects, reducing the overall time required for the exam schedule. This is particularly important in high school settings where time is a valuable resource. The consistent duration also facilitates the comparison of student performance across different subjects and grades.

Furthermore, the 90-minute duration is reflective of the school's commitment to providing a balanced educational experience. It acknowledges the importance of both academic rigor and student well-being. By allocating sufficient time for exams, Shida High School demonstrates its dedication to ensuring that students are not rushed during assessments, which can negatively impact their performance and mental health.

In conclusion, the exam duration at Shida High School is 90 minutes per subject, a length that is supported by research on cognitive processing and educational efficiency.
