ATTENDANCE POLICY:    Classes meet twice a week; 1 hr.-40 min. lecture/demo (Wednesday 3:00 - 4:40) & a 1 hr.-40 min. CAD lab.  Attendance is required at all sessions and will be taken.  No more than two absences are allowed for any reason. (See ET Pandemic Procedures).  A 3rd absence will result in a 10% reduction of your final grade.  Four absences will result in a 20% reduction of your final grade.  Five absences = 30% reduction and six absences will result in failure of TECH104.

GRADING:    Course grades are based on a percentage of total accumulated points of the following items: Written Midterm Exam = 100 pts. / Midterm Lab Practical = 100 pts. / Written Final Exam = 100 pts. / Final Lab Practical = 100 Points / Weekly quizzes = 10 points each / Sketching assignments = 10 pts. each / CAD lab problems = 10 - 20 pts. each. All lab problems must be turned in the following week after they are assigned.  Prior notice must be given in the event of a time conflict with test times and dates. Upcoming lecture outlines and assignments will be posted on the web. Compiling and reviewing these will assure success on tests and quizzes.

96.6 % = A+ 93.3 %= A 90% = A- 86.6% = B+ 83.3 %= B 80 %= B- 76.6 %= C+ 73.3 % = C 70 %= C- 66.6 %= D+ 63.3 %= D 60 %= D-

ACADEMIC HONESTY:    You are expected to follow the standards set forth in the Student Handbook as to academic honesty. Specifically, assignments are to be completed by the individual student unless it is a group assignment. Plagiarism of assignments will be considered a major violation of the Student Code of Honor and will result in failure of TECH 104. (See Academic Integrity).
