COURSE: PC Maintenance and Repair
Prerequisite: None
INSTRUCTOR: Daniel L. Berry
MEETING: Monday and Wednesday / Tuesday and Thursday 6:00 to 9:00 P.M.
TEXT: JES A + books
OBJECTIVE:
The students will demonstrate an understanding of basic PC maintenance
and repair skills and apply them to real world situations.
The students will also demonstrate their abilities in taking a CompTIA
A + Certification Exam.
GRADING: Tests/Projects 65%
Homework/lab Projects 35%
TESTS:
There will be no makeup tests. At the end of the quarter, the
lowest test grade will be dropped and the remaining test grades averaged.
Projects may be assigned in lieu of tests at the discretion of the instructor.
ATTENDANCE:
Attendance is extremely important. If a student is not in class,
he or she misses out on a learning experience. Attendance also reflects
a student's attitude toward learning, and habits developed in school are
carried over to the workplace. Students should be in the classroom
ready to begin when the bell rings.
PARTICIPATION:
Be prepared by reading assigned material before class and be ready
to participate in classroom discussions.
TIMELINESS:
Timeliness is critical in the business world. In order to stress
this reality, there will be consequences for assignments which are turned
in after the due date. Homework/ lab assignments must be turned in
on the day they are due or they will be counted as late. For each
day a homework/lab assignment is turned in late, 10% will be deducted from
the student's grade. The latest a homework/lab assignment can be
accepted is five school days past the assignment due date. If a homework/lab
assignment is turned in past this five day cutoff period, the student will
receive a zero grade. There will be no exceptions to this rule.
If a student is not here on the day an assignment is made, it is the student's
responsibility to become aware of the assignment by contacting the instructor
or fellow student. Also, if a student is absent on the due date of
an assignment, it is his or her responsibility to insure the assignment
is turned in on time.
