READ THE FOLLOWING DIRECTIONS CAREFULLY
1.
In addition to this test booklet, you should have an answer sheet.
2.
Each item in this test has four suggested answers lettered (A), (B), (C), (D). Read each item you are
about to answer and decide which choice is best.
3.
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.

second
The best answer to this item is "metre" so answer space (B) has been shaded.
4.
Ifyou wantto change your answer, be sureto erase your old answer completely and fill inyour new choice.
5.
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 next one. You can come back to the harder item later. Your
score will be the total number of correct answers.
6.
Figures are not necessarily drawn to scale.
7.
You may do any rough work in this booklet.
8.
The use of non-programmable calculators is allowed.
9.
This test consists of60 items. You will have 75 minutestoanswerthem.
10.
Do not beconcemed that the answer sheet provides spaces for more answers than there are items inthis
test.
DO NOT TURN THIS PAGE UNTIL YOU ARE TOLD TO DO SO.
