Criteri, regole e procedure per l'esame
The exam aims to assess the knowledge of inorganic and organic general chemistry acquired by the student during the course. The written exam also aims to verify the student's ability to solve stoichiometric calculations on chemical and electrochemical reactions, thermochemical equations, gas and liquid solutions.The examination consists of a computer test followed by a written test and, if required, by an oral test. No teaching material is allowed in any test.The duration of the computer test is 30 minutes and the test consists of 15 multiple choice questions. The maximum score achievable at the computer test is 12. If the score achieved at the test is less than 8, the examination is registered as failed. If the score is in the range 8-12 the student must attend the written test, consisting of both exercises and theoretical questions. The duration of the written test is 1 hour. The written test allows achieving a maximum score of 18. If the score obtained in the written test is less than 10, the examination is registered as failed. The final mark is the sum of the marks obtained at the computer test and the written test.
If the final grade is equal to or greater than 18/30, the student has the opportunity to request and sit for an additional oral examination. In this case, the final vote will also take into account the oral test. In the absence of the oral examination requested by the student, the final grade will be the one obtained from the test and written examination.
In addition, the teacher can always convene the student for an oral examination, in order to confirm the written part grade.
