Subject: Request for Change in Timetable

Dear Dean [Dean's Last Name],

I hope this email finds you well. I am [Your Full Name], a [Your Year] year student in the [Your Department] department. I am writing to you to request a change in the current timetable for our department.

The current timetable has been quite challenging for many of us in the department. The back-to-back classes without any breaks in between have been causing a lot of stress and fatigue, affecting our ability to concentrate and perform well in our studies. Additionally, some of us have part-time jobs or internships that we are committed to, and the current timetable is making it difficult for us to manage our time effectively.

I believe that a slight modification in the timetable, such as introducing short breaks between classes and spreading the classes more evenly throughout the week, could greatly improve our academic performance and overall well-being. This would also allow us to better manage our time for other commitments.

I understand that changing the timetable might affect other departments and schedules, but I kindly request you to consider our situation. I am confident that a more balanced and flexible timetable will not only benefit us students but also enhance the quality of education in our department.

Thank you for taking the time to consider our request. We are more than willing to discuss this further if needed. We appreciate your understanding and support in this matter.

Best regards,

[Your Full Name] [Your Student ID]
