Grading: 5-6 sets of homework problems, which contain laboratory exercises based on MATLAB, in addition to regular homework exercises. There are two in-class mid-term exams and a final exam.

Tentative Grading Policy: 30% of (Projects, Homeworks, Quiz), 20% of Midterm1, 20% of Midterm2, and 30% of Final exam.

IMPORTANT NOTE:

Score 1 = (0.30×(Projects and/or HWs and/or Quiz) + 0.40 × Midterm Exams Result) / 0.70
Score 1 values will be used to rank students. Students who get reasonably high Score 1 values will earn the right to take the final exam. Students who get low Score 1 values will not earn the right to take the final exam and will automatically receive F from this course.

Score 1 = (0.30×Projects,HWs,Quiz Average + 0.40×Midterm Exams Result+ 0.30xFinal Exam Result

Score 2 values will be used to rank the students who receive the final exam. Students who get reasonably high Score 2 values will manage to earn a passing letter grade such as AA, BA, BB, CB, CC, DC, or DD. Students who get low Score 2 values will receive F. Students who receive F based on their Score 2 values will have the right to attend to the final make-up exam (bütünleme). The students who earn the right, but do not attend to the final exam will also have the right to take the final make-up exam given that they have a valid reason.
