THIS EXAMINATION SHOULD BE PRINTED ON 8% x 14 PAPER, AND STAPLED WITH 3 SIDE STAPLES7 SO THAT IT OPENS LIKE A LONG BOOK. There are FOUR versions of this examination. Each of them should be printed with a DIFFERENT COLOURED COVER. IN THE EXAMINATION ROOM VERSIONS ##172 OF THE BOOKS SHOULD BE ALTERNATED IN ONE ROW (=STRIPE=OOLUMN) AND VERSIONS ##BA IN THE ROWS (=STRIPES=COLUMNS) ON EITHER. SIDE, WITH A DIFFERENT PAIR OF BOOKS USED IN ALTERNATE ROVVS, SO THAT NO STUDENT IS NEXT ON ANY SIDE TO A STUDENT WRITING’THE SAIVIE COLOUR OF EXAMINATION. NORMALLY THIS BOOK IS ENOUGH FOR ALL THE STUDENT’S WRITTEN WORK, including rough work; STUDENTS SHOULD NOT NORMALLY BE GIVEN A BLANK EXAMINATION BOOKLET IN ADDITION.

All your writing — even rough work — must be handed in. You may do rough work anywhere in the booklet. 3. Calculators are not permitted. 4, The examination booklet consists of this cover, Pages 1 through 7 containing questions; and Pages 8, 9, and 10, which are blank. Your neighbour’s version of this examination may not be the same as yours. 5. There are two kinds of problems on this examination, each clearly marked as to its type. 0 Some of the questions on this paper require that you SHOW ALL YOUR WORK! I Their solutions are to be written in the space provided on the page where the question is printed. When that space is exhausted, you may write on the facing page. Any solution may be continued on the last pages, or the back cover of the booklet, but you must indicate any continuation clearly on the page where the question is printed! 0 Some of the questions on this paper require only BRIEF SOLUTIONS ; for these you are expected to write the correct answer in the box provided; you are not asked to show your work, and you should not expect partial marks for solutions that are not completely correct. You are expected to simplify your answers wherever possible. You are advised to spend the first few minutes scanning the problems. (Please inform the invigilator if you find that your booklet is defective.) 6. A TOTAL OF 70 MARKS ARE AVAILABLE ON THIS EXAMINATION.
