A study plan has to be compiled from Poliself by selecting among the courses available from the application courses that satisfy the rules defined for each cycle. It can be updated in given time slots defined by the School. Any change in the study plan should be approved by the Tutor. Since she/he cannot know when you fill in or update the study plan, you should send a copy of it to your Tutor and ask the Tutor for approval; if approved, the Tutor should answer your email approving inserting in cc the phd office (firstname.lastname@example.org).
The schedule of each course is available on the course description here, and also from the study plan application.
