Assessment methods
The written exam consists in 6 exercises that must be solved in no longer than 3 hours. Two exercises for each macro section discussed in class (equilibria, titration and data analysis) will be assigned. The written exam will be passed with an evaluation not lower than 18/30 and allows the access to the oral exam. During the written exam it is allowed the use of a calculator. The use of the smartphone is not allowed. Paper material (first and second drafts) will be provided by the teacher.
During the oral exam it will be ascertained the comprehension of the theoretical and applicative as-pects of the topics discussed in class through an interview.
The final mark will account of the three tests (laboratory, written and oral). However, the final mark does not necessarily corresponds to the arithmetic average of the three partial marks.
