Assessment methods and Criteria
The knowledge and skills acquired by students will be verified through a written test. After completing about half of the program, a partial test (prova in itinere) is scheduled to ascertain the student's actual level of learning. The ongoing test will consist of 15 multiple choice questions concerning the program carried out up to and including the functional group of alcohols. The time available to the student will be one hour.
The written test of the final exam will include the resolution of 15 multiple choice questions concerning the topics of the first part of the course (up to the functional group of alcohols included) plus 5 open questions concerning the second part of the course (from the carbonyl group to the end) . The student will have up to 2 hours available. The student must deserve a score of at least 18/30 to pass the exam.
The final result will also take into account the evaluation obtained by the student in the practical laboratory exercises which are mandatory. The student will be evaluated on the basis of the general behavior during the laboratory exercises and the completeness/correctness of the reports presented at the end of the exercises themselves.

Assessment methods and Criteria
The knowledge acquired by the students is verified through a written test. After completing approximately half the program, a partial test will be scheduled to ascertain the student's actual learning level.
Written test: the written exam will be divided into two parts. The first part will include multiple-answer exercises (15 questions from 1 point each, no answer 0, wrong answer -0.25) on the program held in class up to the first partial test. The second part will focus on the program carried out in the second half of the course. It will consist of five open-ended exercises, one of which will be inherent to practical laboratory. Each open-ended exercise will be worth 3 points. The student will have at least one hour for each part (at least two hours for the whole written exam). Passing the exam requires the achievement of at least 8/15 in each of the two parts and the overall grade of 18/30.
The final mark will also take into account the evaluation obtained for practical laboratory exercises. The student will be evaluated based on her/his general behaviour during the laboratory exercises and on the completeness/correctness of the reports to be presented at the end of the exercises themselves.
