WAEC Syllabus for Chemistry & Recommended Textbooks 2022

The WAEC syllabus for Chemistry is the topic you must study to sit for the examination. It contains the aims and objectives, notes and format for the Chemistry exam.

Studying the Chemistry syllabus is necessary for your exam preparation. It will serve as a guide for you to know the topics to read. There are also notes on concepts you should pay attention to learning.

Exam preparations without using the Chemistry syllabus are like going to the farm without your agricultural tools. You will end up not being productive.

Ensure you begin your exam preparations using the syllabus.

This post contains the Chemistry syllabus and recommended textbooks of the West African Examination Council (WAEC).

Let me know in the comment section if you have any questions. I will love to hear from you.

WAEC Syllabus for Chemistry

This syllabus is drawn purposely for examination, hence the topics are not necessarily arranged in the order in which they should be taught.

The following assumptions were made in drawing of the syllabus:

  • That candidate must have covered the Integrated Science/Basic Science or General Science and Mathematics syllabuses at the Junior Secondary School (JSS)/Junior High School (J.H.S) level;
  • That candidate would carry out as many of the suggested activities and project work as possible, and consequently develop the intended competencies and skills as spelt out in the relevant Chemistry teaching syllabuses;
  • That schools which offer the subject have well-equipped laboratories.

Note: Candidates are required to have knowledge of the significant figures, S.I. units and the conventional/IUPAC system of nomenclature.

Aims

The aims and objectives of the syllabus are to assess candidates’

  • understanding of basic chemistry concepts;
  • level of acquisition of laboratory skills including awareness of hazards and safety measures;
  • level of awareness of the inter-relationship between chemistry and another discipline;
  • level of awareness of the linkage between chemistry and industry/environment/everyday life in terms of benefits and hazards;
  • skills of critical and logical thinking.

Examination Scheme

There shall be three papers – Papers 1, 2 and 3 all of which must be taken. 

Paper 1 and 2 shall be composite papers to be taken in one sitting.

Paper 1

Will consist of fifty multiple-choice objective questions drawn from Section A of the syllabus (ie 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 1 hour 30 minutes alternative to a 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;

The third question shall test candidates’ familiarity with the practical activities suggested in their teaching syllabuses.
