how will draw Use Case ?

As part of the teaching activities management at the University of Jeddah, we would like to manage the classrooms booking as well as teaching equipment (laptop and/or video projector). - Only teachers are authorized to make classroom and equipment booking (depending on the availability of rooms or equipment). - The schedule of rooms could be displayed by all the university teachers and students. - The summary of class booking times for each teacher could be viewed only by the teachers. Note that the summary of class booking times is calculated from the room schedule. - For each course, there is a responsible teacher. - Only the responsible teacher can edit the schedule for the whole course
