Administrative Policy

-          Each student′s final grade will be determined based on the following contributions:

Assessment Method

Percent of Final Grade

Homework Assignments

10%

Quizzes

10%

Two Term Tests

40%

Final Examination

40%

 

-          There are weekly homework assignments. Only three problems from each assignment will be graded.

-          Quizzes will be given intermittently throughout the semester.

-          The two term tests and the final examination will be closed book, closed notes.

-          Minimum aggregate scores for the letter grades A, B, C, and D will be no higher than 90, 80, 70, and 60%, respectively. This scale may be adjusted downward at the lecturer′s discretion.

 

Tips for Success:

-          Come to class. Stay awake in class. Ask questions when you feel confused. Never be hesitated!

-          Write down all necessary lecture notes in a neat way. Make sure you understand the lectures and examples in class.

-          Please read the chapters in advance if possible. I know that many classes ask for this, and few people do it. The reason for this is simple. Class time is free, very effective study time. If you have a clue going in, you will get much more out of class. You will most likely need to study less and still get better grades.

-          Before doing your homework, read your lecture notes and textbook, make sure everything is clear. You need to understand the few fundamental circuit principles. The homework assignments are often simple problems that you can solve easily by applying one or two circuit principles. Do not make things complicated. Even complex problems will become easy to solve by establishing a few equations using the circuit laws. If you are faced with a seemingly difficult challenge, go back to the principles and try to apply them to your circuits.

-          Make good use of office hours. Do not be hesitated when you need to see me or the TA for help.

-          Make an honest attempt at everything. For example: if you are taking a test and have no idea on a problem, write down some circuit laws you remember and tell me that you do not know how to exactly apply them to the problem, but here is what your engineering gut feel is and how you would go about solving the problem. You will get at least some points by telling me how you would solve the problem than leaving it blank or attempting to solve it with randomly recalled useless equations.
