Assessment methods

The examination is written and consists of two parts. It is obligatory to enrol in the Amaesami list of exams for both parts of the exam.

During the exam, it is forbidden to use any electronic equipment connected to internet; otherwise the exam will be cancelled.

The first part lasts for 2 and 1/2 hours and it consists of multiple choice and traditional exercises. Students may use their own books and notes. It is forbidden to use any electronic device. The highest rank of this part is 16. If the student achieves 6.5/16 or more in the A part, they may partecipate in the B part.

The B part lasts for 1 h and the students may take only the pen with themselves. In this part, the student must solve one of the multiple choice exercises of their A part and must answer to two theoretical questions following the proposed draft. The highest rank for this part of the exam is 21.

The final mark is obtained adding the marks of both parts. Final marks greater than 30 will correspond to 30/30 cum laude on Almaesami.

The student may check his work during a special office hours before the verbalization of all valid marks.

Further piece of information on exams is available in the web pages http://www.unibo.it/docenti/simonetta.abenda .

The dates of the exams are published on Almaesami.

Facsimiles of the part A written examination are avalaible in the Alma Campus collection.
