Attendance: 

  1. If a student misses three class meetings the instructor may drop that student from the class.
  2. If a student comes to class after roll has been taken, (tardy), it is his/her responsibility to let the instructor know that they are present
  3. Three times tardy will equal one absence.
  4. You should make an effort to notify the instructor by phone if you are going to be absent from class.
  5. It is the student’s responsibility to find out what material was covered while they were absent.
  6. Each student will receive 5 grade points for being present and on time for each lecture period.

 

The Instructor Reserves The Right To:

  1. Make changes on homework assignment due dates.  Most written homework assignments will be given on Wednesday and will be due the following Monday.  Late homework assignments will not be accepted.
  2. Change the point value of Mid Term and Final Exams.
  3. Change the number of homework assignments and quizzes as may be necessary to cover the classroom material.
  4. Change the Possible Total Points Value

 

 

Note:    Written weekly quizzes will be based on material covered in lectures and homework assignments.

There also will be random welding quizzes assigned, to be done during the weekly lab hours. Each welding quiz must be done during the week that it is assigned.
