Read carefull heck that the answer sheet prvided is fr Mathematics Higher Prelim 00/0 (Sectin ). Fr this sectin f the eaminatin u must use an H pencil and, where necessar, an eraser. Make sure u write ur name, class and teacher n the answer sheet prvided. The answer t each questin is either,, r. ecide what ur answer is, then, using ur pencil, put a hrizntal line in the space belw ur chsen letter (see the sample questin belw). 5 There is nl ne crrect answer t each questin. 6 Rugh wrking shuld nt be dne n ur answer sheet. 7 Make sure at the end f the eam that u hand in ur answer sheet fr Sectin with the rest f ur written answers. Sample Questin line has equatin. If the pint (k,7) lies n this line, the value f k is 7 5 The crrect answer is. The answer shuld then be clearl marked in pencil with a hrizntal line (see belw). hanging an answer If u decide t change an answer, carefull erase ur first answer and using ur pencil, fill in the answer u want.
