EXAMINATION RUBRIC
The examination will consist of
two papers. Paper 1 (032/1 Chemistry 1 Paper) and Paper 2 (032/2 Chemistry 2
Paper).
4.1
032/1 Chemistry 1
This will be a theory paper of three
(3) hours. The paper will consist of sections A, B and C with a total of 14
questions. Candidates will be required to answer a total of 13 questions
which will weigh 100 marks
.
Section A will consist of
two (2) questions. One question will be a multiple choice with 10 items
carrying one (1) mark each. Another question will consist of five (5)
matching items carrying one (1) mark each. Candidates will be
required to answer both questions. This section will weigh a total of 15
marks.
Section B will consist of 10
short answer questions, each carrying seven (7) marks. Candidates
will be required to answer all the questions. This section will weigh a
total of 70 marks.
Section C will consist of two
(2) questions which will either be essay or structured questions, each
carrying 15 marks. Candidates will be required to answer only one (1)
question.
4.2
032/2 Chemistry 2
This paper will either be Actual
Practical or Alternative to Practical. Three equivalent alternatives of the
actual practical paper (032/2A Chemistry 2A, 032/2B Chemistry 2B and 032/2C
Chemistry 2C) will be set. Only one alternative to practical paper (032/2
Chemistry 2) will be set. Candidates will be required to sit for either the
actual practical or the alternative to practical paper. The actual practical
paper will be for 2½ hours. This paper will consist of two (2) questions.
Candidates will be required to answer all the questions. Each question
will carry 25 marks, making a total of 50 marks. The alternative
to practical paper will be of 2½ hours. This paper will consist of five
(5) questions. Candidates will be required to answer all the
questions. Each question will carry 10 marks, making a total of 50 marks.
Note
(i)
The
actual practical paper will have more than one alternative paper which will be
sent to schools depending on the number of candidates. Alternative A will be
sent to schools with up to 100 candidates, alternatives A and B to
schools with candidates up to 200 and alternatives A, B and C to schools with
more than 200 candidates.
(ii)
(ii)
A check-list of apparatuses and chemicals required for the examination will be
sent to schools not less than three months before the date of sitting for the
actual practical paper. However, 24 Hours Advance Instructions will be
dispatched in advance for opening 24 hours before the beginning of the examinations
for laboratory arrangements to be made.
(iii)
(iii)
The use of authorised Qualitative Analysis Guide Booklets and non-programmable
calculators will be allowed in the examination room.
