Let’s begin…

NECO Chemistry Exam Structure

The exam is divided into three papers:

SECTION 1

Paper 1: Objective Questions

  • 50 multiple-choice questions
  • 60 minutes
  • Total of 50 marks

Paper 2: Essay/Theory

  • Covers the entire syllabus
  • 2 hours
  • 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: Practical Test (or Alternative to Practical)

  • 2-hour practical test for school candidates
  • 1 hour 30 30-minute alternative to practical work test for private candidates.
  • Each version of the paper shall contain three compulsory questions
  • 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.
