manual.
New lab
(2) Course Grading System:
(A) Lab.
 The lab grade will come from graded lab reports, pre lab tests, and a possible written
lab final.
o Each lab report will worth a specified number of points. The point value for
each experiment is listed below.
 Lab reports should be completed individually.
 Review questions for each experiment will be due at the beginng of
each lab meeting.
o Pre lab tests may be given prior to the start of the lab. These tests will be short
and worth only one-two points. The pre lab test points will be included in the
lab report grade. You must be present to take the pre lab test.
 10% of the lab grade will come from either assigned homework.
Homework will be due at the start of class on the due date.

(B) Lecture
If the four lecture tests are taken, the lowest test grade will be dropped. The first test missed for any
reason is automatically the test dropped.
3 tests:
300 total points
Final exam: 100 total points
Lab Grade: 100 points
Max course points = 500 total
A (90-100%) =450-500 total points
B (80-89%) =400-449 total points
C (70-79%) =350-399 total points
D (60-69%) =300-349 total points
F (0-59%) =000-299 total points
(D) The final exam is a HCCS system final exam and is required. The final exam grade will
not be dropped.
(3) Honesty:

Please be aware that the HCC rules regarding cheating will be enforced. Anyone
caught cheating either will receive a grade of zero or be dropped from the course.
(4) Makeup Tests/Labs:
 Makeup tests will not be scheduled. You may drop one of the four lecture tests.
 The first test missed for any reason will be the test dropped.
 Due to the large number of wet labs, makeup labs might not be possible. Don’t miss
a lab.
(5) ADA Requirements:
 The Houston Community College System obeys all ADA requirements.
 If you need assistance, contact the Disability Support Service Office at
dsso.nw@hccs.edu or telephone 713-718-5422.
(6) Students taking a class more than two times may face an increase in tuition as mandated by
the State of Texas. Please don’t drop a class without careful thought. Tutors are available.
(7) STUDENTS MUST WITHDRAW, OR BE WITHDRAWN before 4:30 PM on March 29,
2012. AFTER THIS DATE, YOU WILL RECEIVE A GRADE IN THE COURSE.
(8) You will need to activate your HCCS student email account. Go to
