With this function you can construct your weekly calendar of lessons, which is customized on the basis of the courses that you intend to follow.
Warning: the personal schedule does not replace the presentation of the study plan! It's an informal tool that can help you better manage the organization of class attendance before the study plan presentation.
After the study plan presentation we recommend you to use the Lecture timetable service in your Online Services.
To create your customized schedule follow these instructions:
- Click on the "Enable" link to proceed. You will be asked your surname and first name in order to determine your alphabetic grouping.
-
To add or remove courses from your personal schedule, use the small icons which are found next to the courses:
 addition of the course removal of the course selection of the section of the Laboratory of Architecture
(Note: the effective area in which the teaching will be carried out will be determined after the presentation of the Study Plans)
-
The sidebar on the left displays the number of lessons included in schedule.
There are also these commands:
 View the schedule: allows the viewing of the weekly synoptic schedule Delete the schedule: cancels the selections made
When you have finished the entry, you can print the calendar you have made.

Note on the teaching activities
|
The calculation of the number of students enrolled only considers students enrolled in the academic year in question and does not include any possible students who may be attending but who are enrolled in previous academic years.
In case of structured courses taught by more professors, the number of students enrolled is related to the individual professor module, while the students opinion of the teaching is related to the course as a whole.
The data related to the last academic years (number of students enrolled and students opinion of the teaching) have not yet been defined.
