SPECIMEN PAPER



Paper 01 – General Proficiency



75 minutes


READ THE FOLLOWING INSTRUCTIONS CAREFULLY



1. This paper consists of 60 items. You will have 75 minutes to answer them.


2. In addition to this test booklet, you should have an answer sheet.


3. Each item in this test has four suggested answers, lettered (A), (B), (C) and (D). Read each
item you are about to answer and decide which choice is best.



4. On your answer sheet, find the number which corresponds to your item and shade the space
having the same letter as the answer you have chosen. Look at the sample item below.



Sample Item



The SI unit of length is the


Sample Answer

(A) metre
(B) newton


A B C D

(C) second

(D) kilogram


The best answer to this item is “metre”, so answer space (A) has been shaded.



5. If you want to change your answer, erase it completely and fill in your new choice.


6. When you are told to begin, turn the page and work as quickly and as carefully as you can.
If you cannot answer an item, omit it and go on to the one. You can return later to the item

omitted. You score will be the number of correct answers produced.



7. You may do any rough work in the booklet.


8. Figures are not necessarily drawn to scale.


9. The use of silent electronic calculators is allowed.
