Attendance
• Arriving late to lab- If you arrive more
than 5 minutes late, you will not be
allowed to turn in the prelab assignment
which will result in a loss of 2 points.
• If you arrive more than 15 minutes late,
you may turn in your lab report with a 2
point penalty, but YOU WILL NOT BE
ALLOWED TO ATTEND LAB.
Attendance
• Absence- Excessive lab absences will result
in you being dropped from the lecture and the
lab portion of the course.
• If you cannot attend a lab, you cannot make it
up unless you get approval from your current
instructor AND the instructor you intend to
make up your lab with.
– Any lab make-ups must occur during the
SAME LAB WEEK.
– You may not make up more than one lab
this way; unless there are special
circumstances that have been cleared with
your instructor.
Points in Laboratory
• 144 points- 12 labs worth 12 points each
– Most labs have a prelab worth 2 points and
the report worth 10 points
• 100 points- Lab Final
– Review is in the back of your lab manual
• Lab points are added to points in lecture to
give you a course grade
– Labs are about 31.5% of your grade
Late Lab Assignments
• Labs and prelabs must be turned in within the
first 5 minutes of your lab period.
• Prelabs will not be accepted after five-minute
grace period.
• Labs turned in after this five-minute grace
period will lose 2 points.
– For example, if you are late for every lab you will
lose 20 points and your entire course grade is
lowered by 2.7%.
• Labs that are turned in the following week (1
week late) will lose 5 points.
– If you can’t turn in the lab on its due date due to an
absence, you may turn it in the following week for
no penalty (if the absence was an OCC
sanctioned excuse).
Lab Final
• Lab finals must be taken at the time
specified on the syllabus
• If you miss the lab final
– You may make up the non-practical type
questions of this exam only.
– For example, if 30 of the questions are
“practical” then the best you can do on a
make-up lab final is 70/100.
Academic Honesty Policy
• Dishonest conduct in lecture or lab will not be
tolerated.
• If you choose to cheat, you will be dismissed
from the class and receive an “F” grade on the
assignment/test or in the class depending on the
severity of the offense.
• In addition, administration will be notified for

actions) a notation on your permanent OCC
