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%

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 at least 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.

Academic dishonesty will be dealt with in general accordance with the UNM student code of conduct. Any assignments copied from the instructors' manual for the textbook will be penalized with a failing grade for the course and a report to the Mechanical Engineering department chair. Copying of other students' work will be discouraged in the following manner. If n individual homework assignments are found to be substantially identical, the grade for each will be divided by n. Any instance of unattributed or improperly attributed copying of material from print or online resources and/or copying beyond fair use limits will result in zero grade for the entire assignment. Repeat offenses will prompt a report to the ME department chair and/or a failing grade in the course. 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, A/V streaming, and Web browsing devices in class is not allowed. Eating and sleeping in class are discouraged, persons engaged in these activities may be made fun of.

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. 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.
