Grading and Course Policy

The course will be graded on an absolute scale using percentage scores. A 100% score implies that the student has learned all it was possible to learn in the course. 0% indicates no learning. The marginal passing score is 70%. Scores are converted to grades according to the table below.

93% and higher

A

90 to 92%

A-

87 to 89%

B+

83 to 86%

B

80 to 82%

B-

77 to 79%

C+

73 to 76%

C

70 to 72%

C-

67 to 69%

D+

63 to 66%

D

60 to 62%

D-

57 to 59%
F
Below 57%
F-

There will be one mid-term and one final exam in the course. Homework and independent reading assignments will be given out throughout the semester. Textbook reading assignments are an essential part of the course, as the class notes cannot cover all the necessary textbook material. The overall grade will be determined by the contribution of the exams, homework, and lab projects as follows:

Homework

20%

Lab
45%

Mid-term exam

15%

Final exam

20%

There shall be five homeworks assigned throughout the semester. Late homework will not be credited without extenuating circumstances. Both exams are open-note and open-book. Make-up exams - by appointment and only with extenuating circumstances. Students requiring special accommodations should contact the instructor before the mid-term exam. In homework assignments and exams, partial credit will be given for incomplete problems showing the right steps toward the solution. Refer to the lab manual for the lab report requirements and grading procedures. Attendance records for lectures shall not be kept.

No credit will be given for assignments copied from the instructors’ manual for the textbook. Copying of other students’ work will be discouraged in the following manner. If n assignments are found to be substantially identical, the grade for each will be divided by n. This policy will be enforced strictly, literally and with no regard to specific circumstances. Whining shall carry an extra penalty at the discretion of the instructors.

The use of cell phones, electronic text messaging and Web browsing devices, and iPods in class is not allowed.

Extra credit points will be given for several optional assignments throughout the course. These assignments will be typically based on material not covered in class and will require independent work and/or participation in class. The total of the extra credit points will be 10% of the total course score, allowing students to improve their scores and theoretically making higher than 100% scores possible. An A+ grade will be considered for these 100%+ scores.

The class will meet on Tuesdays and Thursdays at 11:00am in ME208. Class may be rescheduled only well in advance and by the consensus of the participants (including the instructor). The duration of the mid-term exam is one hour. The final exam will be two hours long.
