PREFACE

The Interim Joint Matriculation Board Examination (IJMBE) is a qualifying examination into Nigerian and Foreign Universities. The examination is primarily for Advanced Level subjects for Direct Entry (200 level) into the Universities and two (2) Ordinary Level subjects (English and Mathematics), which are basic requirements for admission into Universities.

The syllabus for the examination was last reviewed in 2004 and the current review exercise (2012) was undertaken to revise the subject content in line with global changes. The review exercise was conducted in phases, in collaboration with Nigerian Educational Research and Development Council (NERDG) and participants were drawn from subject teachers in IJMB affiliated institutions, Joint Admissions and Matriculation Board (JAMB) and Chief Examiners of the various subjects.

The revised IJMBE syllabus is designed to be covered in Nine (9) months over a two (2) semester period. The content is structured in such a way that all the topics to be covered in each semester cut across all the examinable papers in the subject so that all aspects of the syllabus “me covered concurrently. At the end of each subject syllabus, list of basic and other reading texts are provided to guide the operators of the syllabus. For effective coverage of the syllabus, a minimum of six (6) lecture hours per week and for subjects with practical component, an additional three (3) hours of laboratory work per week is recommended. Tutorial classes should run concurrently with the lectures.

This revised IJMBE syllabus will be operational in 2013 and students will be examined on the syllabus from . 2014. Detailed syllabus content for seventeen (17) Advanced Level subjects and two (2) Ordinary Level

subjects are presented in this booklet.’
