We have published the updated NECO Syllabus For Mathematics 2023. So if that is what you are searching for, then read on to know how to access it.

It is essential for every student taking the exam to pass it because it is intended for secondary school students in their final year and is used for admission to higher institutions.

You need a guide like a syllabus or a scheme of work in order to pass NECO or any exam at all with flying colors. Because of this, we have created the NECO Syllabus for Mathematics in order to assist all students taking the NECO exam this year.

Before we give you this syllabus, you should be aware that NECO does not have a syllabus at all, not even on its official website. However, based on previous years, we have discovered that the questions from WAEC and NECO are very similar, indicating that they use the same syllabus. The thorough NECO Math Syllabus is provided below.

## Aims And Objectives

The aims of the syllabus are to test candidates

(i) development of mathematical conceptual and manipulative skills;

(ii) having an understanding of a middle-level course of study

(iii) acquiring knowledge in areas of mathematics that will be useful to aspiring mathematicians, engineers, scientists, and other professionals.

(iv) ability to evaluate data and make a good decision

(v) ability to reason logically, abstractly, and precisely.

## Scheme Of Examination

There will be two papers, Papers 1 and 2, and both must be taken.

PAPER 1: will be made up of forty multiple-choice questions that cover the entire curriculum. All questions must be answered in one hour for 40 points by candidates. Following are the sections of the syllabus from which the questions will be taken:

Pure Mathematics – 30 questions

Statistics and probability – 4 questions

PAPER 2: will consist of two sections, Sections A and B, to be answered in 2 hours for 100 marks.

Section A: consists of eight elementary-level, required questions totaling 48 marks. The questions will be given out in the following order:

Pure Mathematics – 4 questions

Statistics and Probability – 2 questions

Section B: will be divided into three parts and will include seven questions that are longer and more difficult:Parts I, II, and III are listed below:

Part I: Pure Mathematics – 3 questions
