EXAM DURATION

HIGHER LEVEL = 3 HOURS

ORDINARY LEVEL = 3 HOURS

EXAM PAPER STRUCTURE

THREE SECTIONS IN EXAM PAPER

SECTION A = MIXED TOPIC SHORT QUESTIONS

FOUR SHORT QUESTIONS (ANSWER ANY THREE)

SECTION B = CORE GEOMETRY

THREE LONG QUESTIONS (ANSWER ANY TWO)

SECTION C = APPLIED GRAPHIC

FIVE LONG QUESTIONS (ANSWER ANY TWO)

EXAM GUIDANCE

• TIMING: HIGHER & ORDINARY LEVEL: 3 HOURS (180 MINUTES)

SPEND 3 TO 5 MINUTES PREVIEWING EXAM PAPER AT START

SECTION A: RECOMMENDED TIME = 45 MINUTES MAX

SECTION B: RECOMMENDED TIME = 65 MINUTES MAX (32.5 MIN/QUESTION)

SECTION C: RECOMMENDED TIME = 65 MINUTES MAX (32.5 MIN/QUESTION)

KEY TIP: WHEN STUDYING, GET INTO THE HABIT OF DOING QUESTIONS RELATIVE

TO THE TIMING SUGGESTED. WHEN IN THE EXAM, HAVE TIME QUES OR BE

VIGILANT OF TIME DURING THE EXAM TO REMIND YOU TO PROGRESS FROM

ONE QUESTION TO ANOTHER.

EXAM GUIDANCE

• SUGGESTED APPROACH: BE ‘SMART’…

DON’T PANIC, EASY FOR ME TO SAY BUT REALLY DON’T PANIC. THE EXAM PAPER WILL LOOK DIFFERENT BECAUSE ALL OF THE QUESTIONS ARE NEW AND PREVIOUSLY UNSEEN. TAKE A MINUTE TO RELAX AND THEN CONFIRM TO YOURSELF THAT YOU ARE REFINED IN THE METHODS /UNDERSTANDING TO ANSWERING SUCH QUESTIONS. REMEMBER THAT YEAR ON YEAR THE FACE OF THE QUESTIONS MAY CHANGE BUT THE DETAIL IS THE SAME, THE METHODS ARE CONSISTENT AND THERE IS A LOGICAL SEQUENCE TO BE FOLLOWED IN ALL CASES.

UPON REVIEW OF EXAM PAPER, MARK THE QUESTIONS YOU FEEL MOST CONFIDENT ABOUT DOING

DO SECTION ‘A’ FIRST AND BEGIN WITH WHATEVER QUESTION YOU FEEL YOU CAN ANSWER BEST

MOVE ONTO SECTION ‘B’ AND AGAIN BEGIN WITH YOUR STRONGEST QUESTION

MOVE ONTO SECTION ‘C’ AND ONCE MORE BEGIN WITH YOUR STRONGEST QUESTION

IN ALL CASES, REMEMBER TO DOUBLE CHECK WHAT THE QUESTION IS ASKING YOU. IT IS NOT UNCOMMON TO PRESUME SOMETHING OR OVERLOOK SOMETHING. BE DILLIGENT HERE.

IF ALL ELSE FAILS JUST HAVE A GO. DO WHAT YOU CAN AND REMEMBER AN AUXILIARY VIEW HERE OR THERE WILL DO NO HARM

IF YOU HAVE TIME AT THE END, SPEND IT BY REVIEWING THE WORK YOU HAVE DONE OR TIDYING UP/FINISHING INCOMPLETE QUESTIONS

DO NOT LEAVE THE EXAM HALL WITHOUT HAVING ATTEMPTED THE REQUIRED AMOUNT OF QUESTIONS TO THE BEST OF YOUR ABILITY.
