The syllabus says the exam is based on the attending programme: assigned readings, slides and class notes, and that every assigned reading must be studied in full, even the parts not covered in class. This site covers all of it:

Blocks 1–5 · Lectures 1–5: the State, Forms of State, unitary, federal and regional states, Italy's regions
Blocks 6–9 · Lectures 6–9: Forms of Government, from parliamentary to neo-parliamentary
Blocks 10–11 · Lectures 10–12: electoral systems and political rights
Blocks 12–13 · Lectures 13–14: sources of law, legal traditions and constitutional amendment
Blocks 14–16 · Lectures 15–16: the European Union, its institutions and its law
Blocks 17–19 · Lectures 17–20: constitutional justice and the Italian Constitutional Court
Blocks 20–21 · Lecture 21: fundamental rights and duties

Slides for Lectures 8–21 of 2026 are not out yet, so those blocks use the 2025 slides, the assigned readings and class notes. Check new slides against the matching block as they appear.
