TEACHERS AND EXAM BOARD

Ricevimento: I'm available every day of the week. Please, contact me before by e-mail for an appointment. 

Ricevimento: The teacher is always present in the Department between 8.00 and 13.00 and 15.00 and 18.30 (except in august). The students can come to speak with him in any moment, unless he is engaged in other isntitutional activities. However, it is highly advised to arrange an appointment by E-mail, in order to be sure to find him free.

LESSONS

Teaching methods

The lessons are given in the traditional way (64 hours in the classroom). The attendance is highly recommende. 

LESSONS START

The lessons will begin february 25, 2019.

EXAMS

Exam description

There will be a preliminary written exam consisting in 12 questions. The students will have 90 minutes for answering. The written exam will be followed, the same day, by an oral exam. At least one question for each of the three parts will be asked at the oral. Only the students who get a sufficient grade at the written exam will be admitted to the oral. The oral exam must be given the same day than the written one and if a student fails to pass the oral, will have to repeat also the written part. In general, the grade of the written exam in not influential on the final vote. Only in particular cases, when the written exam has a very high mark, it can positively influence the final grade.

Assessment methods

The oral exam is always carried out by two members of permanent teaching staff and lasts at least 45 minutes (15 minutes for each professor). The students will demonstrate to have reached a sufficient knowledge both by answering to questions, and by drawing at the blackboard formulas, reaction equations, mechanisms and so on. Therefore, also taking into account the preliminary written part, the commission is definitely able to verify, with high accuracy, the fullfilment of learning outcomes. If the commission decides that the learning outcomes have not been met, the student will be invited to try again the exam in a following date.

FURTHER INFORMATION

Only the students who have already passed Organic Chemistry 1 are admitted to the exam. The professors will check the observance of this rule just before the written exam.
