The Department of Zoology offers courses leading to the award of B.Sc. degree in Zoology
HISTORY OF THE DEPARTMENT
The Department was created during the 1991/1992 academic session when the Department of Biological Sciences was split into three Departments (Botany, Microbiology and Zoology). The first Head of Department was Prof B. A. Obiamiwe who was on sabbatical leave from the Department of Zoology (now Department of Animal and Environmental Biology), University of Benin. The academic staff strength was about eight and the number of students was about 15. Since then, the number of academic staff has oscillated between eight and twelve while that of the students has grown to over three hundred and fifty.
Prof B. A. Obiamiwe handed over to Dr H. M. Yesufu (Reader) as Head of Department during the 1992/1993 academic session. Dr Yesufu was Head of Department for four years (1992/1993 – 1995/1996). Since then the following have been Heads of Department:
The Department of Zoology offers courses leading to the award of B.Sc. degree in Zoology
The programme is designed to adequately expose the students to general and practical education in Zoology. Students are thus trained to respond to the needs of the Nigerian Society through broad training/education in the areas of General and Applied Biology, Invertebrate and Vertebrate Zoology, Developmental Biology, Histology, Genetics, Animal Ecology, Nematology, Animal Systematics, Animal Behaviour, General Physiology, Pollution and Toxicology, Entomology, Hydrobiology, Fisheries,, Aquaculture and Parasitology.
The courses offered in the Department are aimed at:
Admission is by Entrance Examination (UTME) or by Direct Entry. Candidate admitted by UTME undergo a 4-year degree programme while those admitted by Direct Entry do a 3-year degree programme.
GUIDELINES ON COURSE UNIT SYSTEM
1. CATEGORIZATION OF COURSES
(a) Core Courses C)
These are courses that must be mounted by the university, taken by the student and passed in respect of the particular degree programme.
(b) Required Courses (R)
These are courses, which are mounted by the university, taken by the student on the advice of the Department in respect of a particular degree programme which the student may or may not pass.
(c) Elective Courses (E)
These are courses, which are mounted by the University, taken by the student on the advice of the Department in respect of a particular degree programme which the student may or may not pass.
II. PRE-REQUISITE COURSES
(a) Pre-requisite courses are courses, the knowledge of which are necessary prior to the taking of other specified (usually higher level) courses. A student is deemed to have obtained this prerequisite knowledge if he/she obtains a mark not less than 30% but will not be credited with any grades points in the courses concerned, except he/she scores a minimum mark of 40%.
(b) Pre-requisite courses must be reflected where applicable. As much as possible no course should be a pre-requisite for a course at the same level. Rather, such a course should be termed a concurrent course, that is, a course that is taken at the same (session) as the specified course.
III. QUANTIFICATION OF COURSES
(a) Courses are quantified in credit units or units for short. A UNIT equals 15 hours of lectures (i.e. 1 hour a week for 1 semester) or 15 hours of tutorials or 45 hours of laboratory/field work.
(b) No course should be less than 2 units and no lecture course should normally be more than 3 units.
(c) Courses that extend over both semesters (such as practical courses) will be credited at the end of the second semester.
IV. APPROVED DEPARTMENT CODES
BCH for Biochemstry
BIO for Biology
CHM for Chemistry
CSC for Computer Science
STA for Statistics
MTH for Mathematics
MCB for Microbiology

GEO for Geophysics
ZLY for Zoology
V. COURSE ADVISER
A course adviser is a member of Academic Staff who approves student registration forms. He advises students individually and ensures that their choices are consistent with the degree programme regulations and requirements. Each Department appoints one or more course advisers for her students.
VI. CLASS ADMIT/GRADE CARD
A class Admit/Grade Card shall be issued to every registered student and for each course registered for during the session. The card shall enable the lecturer in charge of a particular course exercise control over attendance at lecture. It shall also be used for the submission of grades in the examinations along with the grade points. Lecturers shall be required to certify that a student has attained 80% minimum contact hours before he/she is allowed to take the examination in the particular course.
VII. EXAMINATION PROCEDURE
(a) University examination shall be held at the end of each semester for all semester courses and at the end of each session for all sessional courses.
(b) Only students who are duly registered for courses in a given semester and have met their financial obligations to the university shall be eligible to sit for examination in those courses.
(c) Students who enter for examinations in courses for which they are not duly registered shall not be credited with any grades or units for the courses.
VIII. COURSE ASSESSMENT
(a) In every course, assessment must consist of continuous assessment (between 20% and 40%) and examination (between 60% and 80%)
(b) The pass mark for every course is 45%
(c) The grading system is as follows:
|70 – 100
|60 – 69
|50 – 59
|45 – 49
|0 – 44
(d) Students’ results are to be prepared at the end of every semester, reflecting raw marks and grades, total units taken, total units passed and total units failed.
(e) At the end of every session a summary of students’ results is prepared, level by level, reflecting the units taken during the session, the units passed during the session, the sessional G.P.A., the courses failed for the session, the cumulative units taken, the cumulative units passed, the CGPA, and remarks of proceeding or probation or withdrawal from the (degree) programme as the case may be.
(f) At the end of the degree programme, students’ result are prepared reflecting details of the sessions’ performance, including a list of courses failed for the session as well as the cumulative performance including the degree classification (where applicable) according to the following table.
|CLASS OF DEGREE
|4.50 – 5.00
|3.50 – 4.49
|2nd Class Upper
|2.40 – 3.49
|2nd Class Lower
|1.50 – 2.39
|0.00 – 1.49
(g) Both the sessional GPA and CGPA are calculated using the weighted grade point. The weighted grade point for the course is the product of the point and the units for the course. Thus a student who scores 62% in a three-unit course has a grade point of 4 and a weighted grade point of 3 x 4 = 12 for that course. Thus the sessional G.P.A is calculated from the formula
Sessional GPA = Total Weighted points in the session / Total Unit Taken
Similarly, the CGPA is calculated from the formula;
CGPA = Total Weighted points for all the session / Total Unit Taken
provided that all courses taken that are relevant to a particular degree programme are used in the computation of the various averages.
In computing CGPA, performance in all courses registered for and taken in the course of a particular degree programme must be used.
(h) The inclusion of the column (for cumulative taken) in each of the formulas for presentation of results to Senate and to Faculty Board enables one to keep tract of the weighted product expressed to the nearest integer, of the CGPA and the cumulative unit taken) where applicable.
(i) As an example, consider a student who takes seven course in a semester with the following tabulated details:
|Grade Point (d)
|Weighted Grade Point (a) x (d)
Total Units Taken = 19
Total Weighted grade Point = 42
If the total units taken for the second semester is 25 with a total weighted grade point of 64 the sessional GPA is given by:
(42 + 64) / (19 + 25) = 106 / 44 = 2.41
A student may have the following tabulated results over four sessions:
|Weighted Grade Point
|Cumulative Weighted Grade Point
Thus, the CGPA at the point of graduation is 2.71 hence the student will come up with Second Class Lower Division Degree
(j) There is no reference in any course examination. Long vacation semester has been abrogated.
(k) There is no repeat in the course system. Therefore, a student cannot re-register for a course already passed.
(l) A student must accumulate at least 30 units per level before graduation
(m) There is no weighting of sessional GPA in the computation of CGPA
(n) In the computation of the CGPA all courses taken in the session will be used, and therefore no course will be disregarded or discountenanced.

(b) A student who is unable to take a course examination in a particular course due to approved absence will be required to re-register for the course at the next available opportunity. Such a student will not normally be allowed to take any course for which the incomplete course is a pre-requisite. Please note that a student cannot exceed the approved workload without approval by the University Senate.
(a) A student who makes a CGPA of 1.00 or more at the end of the session will proceed to the next level of the degree programme for which he/she is registered.
(b) A student who makes a CGPA of less than 1.00 at the end of the session will be on probation for the following session to enable him/her improve on the CGPA. During that session he must register for the appropriate core courses and other courses he/she has the pre-requisites before he/she can register for any higher level course.
(c A student on probation during a session who makes a CGPA of less than 1.00 at the end of that session must withdraw from the degree programme for which he/she is registered.
(d if the student changes to a new degree programme and obtains a CGPA of less than 1.00 in the new degree programme he/she will again be on probation. If however, he/she obtains a CGPA of less than 1.00 a second time in the new degree programme he/she will be asked to withdraw from the University.
