REQUIREMENTS FOR HAND-IN ASSIGNMENTS
& OTHER WORTH WHILE INFORMATION
1. Assignments. It is expected that all assignments will represent your best,
professional effort. All assignments will be graded on the copy you turn in to
the instructor. If you wish to keep the original for a record, have a copy made
at one of the blueprint/imaging firms in town. Be sure they are identified! Use
the title block format assigned by the instructor for each assignment.
2. Grading. Assignments will be graded on a point basis. If the assignment is
done perfectly, you will receive the maximum points available for that
assignment. (See the assignment sheet) Errors will reduce the score on
roughly a percentage basis. To help insure a good grade, have the instructor
review the assignment with you before turning it in for grading.
Grading for the course will be as follows:
A = 100-90%
B = 89-80%
C = 79-70%
D = 69-60%
W = 59% and below
3. Due Dates. If you miss a deadline, the following policy will be followed:
a. One week late
= 10% deduction
b. Two weeks late
= 20% deduction
c. Three weeks late
= 30% deduction
d. Four weeks late
= No Grade
4. Attendance. Attendance to lectures is required.
a. If you miss more than three classes, you may be dropped from
the course at the instructor’s discretion.
b. Approximately 3 hours lab time per week in addition to class time will
be required to complete assignments.
c. If you must miss class, you are responsible to find out what was
missed and arrange for any missed assignments.
d. Canceled class hotline number is 445-3030 or 866-532-5118.
5. Classes missed due to school closures will be covered by a double lecture
the class meeting before or after the return to classes.
