Are you preparing to write the Chemistry exam in the upcoming NECO exams? Or do you know someone who is? If yes, then this article will be of great help to you.

This NECO chemistry exam aims to access your:

  1. Understanding of basic chemistry concepts; 
  2. Level of acquisition of laboratory skills including awareness of hazards and safety measures;
  3. Level of awareness of the inter-relationship between chemistry and other discipline;
  4. Level of awareness of the linkage between chemistry and industry/environment/everyday life  in terms of benefits and hazards;
  5. Skills of critical and logical thinking.

    The NECO Chemistry syllabus is like a roadmap that provides an overview of the topics that you need to study and what you should know after reading each topic. Studying this syllabus alongside your NECO past questions is an excellent way to stay ahead of your peers and score good points in your exam.

Marking Guide & Sections

There shall be three papers  – Papers  1, 2  and  3  all of which must be taken.  Papers 1 and 2 shall be a composite paper to be taken in one sitting.

PAPER 1:  

This will consist of fifty multiple-choice objective questions drawn from Section A of the syllabus (i.e. the portion of the syllabus which is common to all candidates).

Candidates will be required to answer all the questions within 1 hour for 50 marks. 

PAPER 2:  

It will be a 2-hour essay paper covering the entire syllabus and carrying 100 marks. The paper will be in two sections; Sections A and B.

Section A: Will consist of ten short structured questions drawn from the common portion of the syllabus. (i.e. Section A of the syllabus). Candidates will be required to answer all the questions for 25 marks.

Section B: Will consist of two questions from the common portion of the syllabus (i.e. Section A of the syllabus)  

and two other questions from the section of the syllabus which is peculiar to the country of the candidate (i.e. either Section B or C of the syllabus). 

Candidates will be required to answer any three of the questions. Each question shall carry 25 marks.

PAPER 3:    

This shall be a 2-hour practical test for school candidates or a 1 hour 30 30-minute alternative to practical work test for private candidates. Each version of the paper shall contain three compulsory questions and carry 50 marks.  

The questions shall be on the following aspects of the syllabus: One question on quantitative analysis; One question on qualitative analysis; and The third question shall test candidates’ familiarity with the practical activities suggested in their teaching syllabuses.

N.B: Details of the input into the continuous assessment shall be given by the Council.
