Somaliland National Examination Certificate of Secondary Education
and Certification Board Maths paper 1 examinations
REPUBLIC OF SOMALILAND
Preface
The administration of Somaliland national examination and certification board
(SLNECB) authorized the compilation, production and publication of Somaliland
national maths paper 1 examination books with simplified answers and solutions for
secondary students. The production of these books came after a success through
great and selfless effort, made by SLNECB and the teacher who compiled it. This was
necessitated by the tremendous needs of the whole Somaliland secondary students
in order that they get equal rights and experience in performing national
examinations in particular and the international exanimations in general.
I hope all Somaliland students and teachers will enjoy using these valuable books.
