Radiative Processes (year 2014-2015)
Lecturer: Alessandro Patruno & Rowin Meijerink
The “Grade” for the final exam is calculated already with the 30%-70% average rule. If the exam score was higher than the average score of your in-class tests then we have kept the exam score as the final (provisional) grade.
The retake score instead is calculated without considering the in-class tests.
