Laboratory sessions are organised in parallel to theoretical study given in classrooms. Students perform at least 8 different experiments and submit reports for evaluation
Midterm I 20%
Midterm II 20%
Final Examination 35%
Makeup Exam & NG Policy:
Only one make-up examination will be given to those who miss the midterm or the final. The student who wishes to take the make-up exam must provide a valid excuse within the next three working days. NG grade will be given to students who do not attend more than 80% of the course lecture and lab hours, and miss one exam.
