VII. Course requirements and Grade computation A. College Requirements A written, comprehensive final exam, not to exceed two and one-half hours in length, shall be given at the end of a semester for each course at the regularly scheduled time. Any exceptions to these requirements must be approved by the Dean of Arts and Sciences. Other examinations are given at the discretion of the instructor. A student who must be absent from the final exam should petition the instructor for permission to postpone it. A student absent without permission from a final exam is graded “F”. Postponed exams result in a grade of “I”. A postponed final exam must be taken within 120 calendar days from the end of the semester or the grade automatically becomes an “F”. (San Antonio College Bulletin, Faculty Handbook – Jan 1995) B. Departmental Requirements All biology courses require basic skill levels in math and reading. C. Instructor Requirements The course grade will be determined by class lecture tests, lecture quizzes and laboratory reports, and a final examination. Lecture exams will count 50% of the final grade. The lecture quizzes will count 10% of the final grade, and laboratory reports will count 15% of the final grade. The cumulative final exam comprises the remaining 25% of the course grade. The lowest grade of the lecture tests will be dropped. There will be no makeup examinations. If a student misses an exam, that grade will automatically be entered as a zero and will be the grade, which is dropped. Course participation and attitude may influence borderline scores for those students who do not miss two or more classes and who have not missed an exam. (A borderline grade is 89.4 or 79.4, not 88% or 78%). Exams will consist of multiple choice and/or completion type questions. Essay questions may sometimes be included. All exam questions will be based on lecture information as well as text material as outlined in the syllabus. Tests may not be taken late under any circumstances. However, tests may be taken early in some cases to accommodate scheduling conflicts such as funerals, hospitalization, etc. providing that proof of these events are provided by the student. D. Exit Competency Biology majors and students wanting to achieve a transferable grade in this course must achieve a cumulative average of 70% or above on all lecture/lab exams, quizzes and cumulative final. Graduation credit can be earned by scoring a 60% or above as per San Antonio College policy. For more detailed information, see individual instructors‟ syllabi. A typical course grade is composed of lecture exams, lab exams, and the mandatory comprehensive final exam. The lecture exams comprise 50% of the overall course grade; the laboratory portion a 25%, and the final exam a 25%. The overall course grade is assigned according to the following scale: A = 90 – 100 B = 80 – 89 C = 70 – 79 D = 60 – 69

F = Below 60

VIII. College Policies: A. San Antonio College does not discriminate on the basis of race, religion, color, national origin, sex, age, or disability with respect to access, employment programs or services. B. Students are urged not to bring children to either a class or a lab. Minors under the age of twelve (12) must not be left unattended on campus. College Academic Council - April, 1998 C. ADA Statement: “As per Section 504 of the Vocational Rehabilitation Act of 1973 and the Americans with Disabilities Act of 1990, if accommodation is needed contact the Office of DisABILITY Support Services, CAC 124C, Phone: (210) 486-0020. D. A Rapid Response Team exists for the purpose of responding to emergencies. If you have a disability that will require assistance in the event of a building evacuation, notify Disability Support Services, Chance Academic Center 124C, Phone: (210) 486-0020. E. Academic Dishonesty: Students may be subject to disciplinary proceedings resulting in an academic penalty or disciplinary penalty for academic dishonesty. Academic Dishonesty includes, but is not limited to, cheating on a test, plagiarism and collusion. For additional information refer to the “Student Code of Conduct” in the San Antonio College Bulletin. F. Students are required to silence all electronic devices (e.g., pagers, cellular phones, etc.) when in classrooms, laboratories and the library. College Academic Council, 01/ 2000. G. San Antonio College Attendance Policy: Regular and punctual attendance at all classes and laboratories, day and/or evening, is required. A student absent for any reason is responsible for all work missed. Both tardiness and early departure from class are forms of absenteeism. The instructor establishes the policy with regard to each. Absences of each student are recorded without exception. The counting of absences begins on the first day of class. A student absent the equivalent of two weeks of instruction in a 16-week semester may be dropped by the instructor. If a student is dropped from a class for excessive absences, the instructor will record a grade of “W‟ (withdraw). It is the student‟s responsibility to ensure that the withdrawals have been submitted. If you decide to drop this course, it is your responsibility to inform the professor. Once you notify the professor of your intention to drop, you can be dropped directly from the computer system by the professor. Paper drop slips are no longer required unless you drop before the census date at the beginning of the semester. If you cannot find your professor to drop, then a drop slip can be obtained in the Biology Department office (CAC345) or counseling and must be signed by your professor, the Biology Department chair or a counselor. If you have not insured that your name is removed from the class roster prior to the drop date, you will earn an “F” for the course. Students who intermittently attend class and laboratory may be dropped from the course at the instructor's discretion without prior notification. An „I‟ grade automatically converts to an “F” after 120 days unless all missed work is completed. H. San Antonio College is a smoke free campus. I. ACCD DPS Emergency Phone Numbers:


DPS Emergency: 222-0911 DPS General: 485-0099 DPS weather: 485-0189 (For information on college closures) Students must also abide by the policies, procedures, and rules set forth in the “Student Code of Conduct” and all other policies set forth in the San Antonio College Bulletin.

IX. Biology Study Center: Room 350 is the Biology Study Center (BSC)/BioSpot. Computer, videotapes, laboratory and reference materials are present for the student's use. A catalog is present in the study center with a list and description of materials that are present. Computers are available in the BSC for web access. You must present your student ID to be able to use the material and/or computers in the BSC. To access the on-line lecture material, use Internet Explorer (do not use the AOL browser or Netscape Navigator) and go to the Blackboard Vista login page at, then log on using the userid you were issued when you registered for this course. It will appear on your bill. Usually the userid is the first letter of your first name and your last name. Sometimes if there are a lot of D. Smith‟s or J. Garza‟s there will be a number added to your userid. Your password is the first two letters of your last name in capital letters and the last 6 digits of your social security number. Once in Blackboard Vista, all the classes you are taking this semester will be listed. Click on Biology 2406, and the course will open in the Blackboard Vista platform. Once on the course opening page, you will see a menu on the left hand border of the screen. There is a mail function that I may use to post messages to you specifically or the class in general.
