Course Grading

The expected learning outcomes will be assessed by review of written assignments (project assignments and other homework), class participation, and performance on the unit tests and the final exams. Project assignments and other homework. Much of the course efforts will be practical in nature (as described in more details in assignments). In addition, short homework assignments may be given from time to time.

Projects/Homework, and class work 30 %
Midterm Exam 30 %
Final Exam 40%
