AIMS AND OBJECTIVES

  1. This syllabus is intended to evaluate candidates on the following criteria:
    Appreciation of nature and knowledge of the structure and activities of living organisms;
  2. Acquiring adequate laboratory and field skills in order to conduct and evaluate biological experiments and projects;
  3. Acquiring necessary scientific skills, such as observing, classifying, and interpreting biological data;
  4. Acquiring the fundamental relevant knowledge in Biology required for future advanced studies in biological sciences
  5. Development of scientific problem-solving attitudes;
  6. Ability to use biological concepts in everyday life in topics affecting personal, social, environmental, community health, and economic problems;
  7. Understanding of interrelationships between biology and other scientific disciplines.

SCHEME OF EXAMINATION

There will be three papers: Papers 1, 2, and 3, all of which must be taken. Papers 1 and 2 will be a composite paper to be taken at one sitting.

PAPER 1: Will consist of fifty multiple-choice objective questions drawn from Section A of the syllabus (the section of the syllabus which is common to all countries). It will carry 50 marks and last for 50
minutes.

PAPER 2: Will consist of six essay questions drawn from the entire syllabus.
The paper will be put into three sections, Sections A, B, and C.

Section A: Will consist of four examination drawn from Section A of
the syllabus.

Section B: This Will be for candidates in Ghana only and will be drawn
from Section B of the syllabus (ie the section of the syllabus
perculiar to Ghana). It will consist of short-structured questions.

Section C: Will be for candidates in Nigeria, Sierra Leone, The
Gambia and Liberia and will be drawn from Section C of the
syllabus (ie the section of the syllabus containing material for those
countries only).
