Biological Sciences and Geology Department
BI-202: General Biology II
Lecture Guidelines
Required Books and Materials:
Campbell Biology 10th Edition Authors Reese, Urry, Cain, Wasserman, Minorsky,
Jackson Benjamin; Cummings, 2011.
Photographic Atlas for the Biology Laboratory Latest Edition, Van De Graaff and
Crawley, Morton Pub. 2001
Dissecting kit (scissors, forceps and probe) and disposable gloves
Grading Procedures and Criteria:
The final grade is a combination of the grades earned in the lecture and laboratory
segments of the course. The lecture average accounts for 60% and the laboratory average
accounts for 40% of the final grade.
5 Lecture Exams

Mobile phone use prohibited before, during or after exams. Five exams (50
minutes) will be given in lecture. Each is equally weighed and none of these exam
grades will be dropped. Make-up exams for absent students are given only under
extreme circumstances and at the instructor’s discretion. Make-ups may vary in
format from the regularly scheduled exams.
Attendance Policy:
Students are strongly encouraged to attend all lecture sessions. Text study alone is not
sufficient! Many topics are complex and additional material may be introduced in lecture.
Excessive absences will result in significant gaps in understanding the material.
Laboratory attendance is mandatory and excessive absences will result in a WU
(unofficial withdrawal) being assigned for the entire course. An absent student must take
the initiative for remaining up to date in the course and is responsible for all covered
material and assigned work.
College regulations regarding cheating will be strictly enforced.
Course Coordinators: Dr. R. Sullivan and Dr. J. Stark
