Readings/Bibliography

K.J. Denniston, J.J. Topping, R.L. Caret Ed. McGraw-Hill 

All the lectures will be supported by PowerPoint presentations, downloadable from iol.unibo [https://iol.unibo.it/course/view.php?id=27988] before the beginning of each lecture.

Samples of the written exam (with solutions) will also be uploaded on iol.unibo [https://iol.unibo.it/course/view.php?id=27988] together with other files containing similar questions and/or exercises.

Teaching methods

Traditional lecture-based teaching based on Power Point presentations.

Attendance to learning activities is mandatory; the minimum attendance requirement to be admitted to the final exam is 66% of lessons. This teaching is a part of the Chemistry and Bichemistry Integrated Course (IC), therefore the 66% attendance requirement refers to the total amount of IC lessons. Students who fail to meet the minimum attendance requirement will not be admitted to the final exam of the course, and will have to attend relevant classes again during the next academic year.

Assessment methods

The assessment of the course contents is based on a final examination only; no midterm exams are scheduled. The final examination consists of a single written exam, having a maximum duration of three hours.

During the examination, only the use of ordinary stationery (i.e., pencils, pens, rubber, rulers, etc.) and of a calculator is allowed. The periodic table (which sample copy is available on AMS Campus) and any other supplementary material will be directly attached to the exam papers. During the examination, students are not allowed to leave the classroom, unless they accept to definitively deliver all their exam papers and do not enter the classroom anymore. During the exam, the presence of electronic devices, other than a simple watch and the aforementioned calculator, is strictly forbidden.

In order to take the exam, students must sign up through AlmaEsami within the indicated deadlines. All the activities associated to the “Biochemistry Laboratory” must be completed and approved, before considering to take the exam. During the examination, students must have an ID document and their university badge.

The overall exam score is 34.00 points, equally divided in 17.00 points for the “Chemistry” part and 17.00 points for the “Biochemistry” one. Each single written exam will include both the “Chemistry” and the “Biochemistry” part and cannot be split.

The exam is passed by achieving at least 9.00 points (out of 17.00) in both parts. The final mark is calculated by summing the points obtained in both the above mentioned parts and rounding it to the nearest integer.

Examples:

  • Chemistry: 10.50 pts + Biochemistry: 8.50 pts
    ---> FAILED
  • Chemistry: 11.00 pts + Biochemistry: 13.75 pts
    ---> 24.75 pts ---> PASSED WITH 25/30.

If a student obtains an overall score of 31 points or more, 30L is assigned.

The exam results will be published online on AlmaEsami. If the exam is passed, the associated mark will be officially registered only after the student's confirmation to be sent to the integrated course coordinator (i.e., Prof. Michele Di Foggia, michele.difoggia2@unibo.it), using the student institutional email (e.g., name.surname@studio.unibo.it).

The registration of a successful examination is permitted no later than 6 months from the date of the exam; after this deadline, the result achieved and not confirmed will expire.

If a student decides to take the exam again, regardless of the associated outcome, the result obtained in the previous examination will automatically be cancelled. The exam can be repeated at any exam session.
