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.
