Teaching methods
The students must take three wriitten tests during the course, each consisting of five problems, very similar to those solved during the <br />practical sessions.<br /><br />Registration to the first written test must be performed both on my.unipr.it (http://corsi.unipr.it/courses/FIS01/index.php) and by filling the <br />form therein (Questionario). <br /><br />Failure in these written tests impies undergoing a full exam (global written test plus oral exam on the whole program).<br /><br /><br />Passing all three tests may correspond to passing the course, with a grade corresponding to the average of the three tests. The candidate may chose instead to take an oral exam on one or more thirds of the program. The final grade in this case is a weighted average among the grades of the tests and of the oral parts.<br />Failing one ore two written tests with an overall pass average grade implies compulsory oral tests only on the failed subjects. The final grade once again is a weighted average of the passed written test grades and of the oral grades. <br /><br /><br /><br />
