Lectures.

Assessment methods

Written examination with open questions. The final mark is the weighted average of the results obtained in the individual disciplines of the course (General and Inorganic Chemistry, Organic and Environmental Chemistry, Biochemistry). To book an exam, the student must use AlmaEsami ( https://almaesami.unibo.it/almaesami/welcome.htm ).
