A. GENERAL GUIDE – Paper 1

Covers all topics from Form 1 to Form 3 and requires skill higher than BASIC SKILL.

Consist of objective questions with 4 choices of answer.

Candidates have to do complete revision covering all topics and do not at all choose certain topics only.

Contains topics covering NUMBERS, SHAPES and ALGEBRAIC themes.

Skills related to NUMBERS, SHAPES and ALGEBRA complement each other ; without any one of the skill, others can’t be acquired. For example, questions on SHAPES require a lot of ALGEBRAIC and NUMBERS skills whilst questions on ALGEBRA require skills on NUMBERS or vice versa.

Skills related to NUMBERS should be built first whilst skills on ALGEBRA are very important to solve many problems.

Paper 1 will take place after Paper 2 has been executed.

All topics in the KBSM Syllabus (Form 1 – 3) with skill higher than basic skill

75 min Objective 40 All 40 % 4 choice of answers are prepared for each question

• Use the final 5 to 10 minutes to recheck answers.• Do not wait till all questions are answered and only then transfering them to the OMR answering paper. Transfer each answer after each question has been answered.• Each question needs more or less 1 to 2 minutes to solve. If it can’t be solved, shift to other question.• If there are still questions that can’t be answered for the second time, you may have to guess the answer. Do so but after all distractors have been removed.

D. FORMS OF QUESTION – Paper 1

“COMMON SENSE” QUESTIONS (NEEDS NO CALCULATION)

EXAMPLE 1 : Mrs Kasmah brings along RM 30 to the market. She used 5 / 10 of her money to buy

1⅔ kg of prawns. What is the price of 1 kilogram of those prawns ?

A. RM 9 B. RM 15

C. RM 16 D. RM 21

C. FORMS OF QUESTION – Paper 1

QUESTIONS THAT CAN BE ANSWERED USING OTHER QUESTION BEFORE OR AFTER IT AS A GUIDE

Example 2 below can be answered using Example 3 as a guide.

EXAMPLE 2 : EXAMPLE 3 :

Amir Amsyar bought a pair of pants Solve the following equation

at a price of RM 42 after discount. 6 – 2x = 4The original price is RM 60. Calculate 3The percentage of discount given.

A. 20 % C. 30 % A. – 2 C. 4B. 25 % D. 35 % B. 3 D. - 3

Page 7: Pmr Mathematics

C. FORMS OF QUESTION – Paper 1

QUESTIONS THAT CAN BE ANSWERED BY TRYING OUT EACH

CHOICE GIVEN (If possible, try not using this method because it

is time consuming)

EXAMPLE 4 :

An electrical appliance company offers

25 % discount to its clients for certain

electrical appliances. Encik Ngapan bought

a refrigirator at an offer price of RM 1080.

What is the original price of the refrigirator ?

A. RM4320 C. RM810

B. RM1440 D. RM2400

Try whether 4320 – 25 x 4320 is 100equal to 1080. If not the same, repeat with other choices. (If possible make a RANDOM choice because we might succeed at first try)

QUESTIONS THAT HAD TO BE GUESSEDBefore guessing, eliminate all the distractors first.

EXAMPLE 8 :

Which of the following is not true ?

Page 16: Pmr Mathematics

A. GENERAL GUIDE – Paper 2

Paper 2 is in the form of written subjective. Questions are constructed according to KBSM syllabus at

minimum to high capability level. Skills tested are basic to high level skills in certain topic

listed in the syllabus . Concepts tested are basic Mathematical concepts that all

Form 3 students should have acquire from certain topic. Questions are phrased in short and moderate sentences

not using long and difficult words. Questions are focused to types that have certain difficulty

level. This allows differentiation between students that acquired basic skill with those that acquired minimum level skill.

Marks are awarded according to working method and precision of answers.

Paper 2 will take place after Paper 1 has been executed.1. Use the final 5 to 10 minutes to recheck answers.2. Each question needs more or less 2 to 3 minutes to solve. If it can’t be solved, shift to other question.3. Usually marks are awarded straight to the precise answer given. If there are any mistake, only then marks are awarded to the working method written.

D. ANSWERING METHODS – Paper 2

IF NO WORKING METHOD CAN BE WRITTEN, JUST WRITE DOWN THE ANSWER.

EXAMPLE 2 :Between translation, rotation, reflection and enlargement, which one involves change of size.

D. ANSWERING METHODS – Paper 2

DRAW DIAGRAM REQUESTED USING GEOMETRICAL

INSTRUMENT (PROTRACTOR, RULER, COMPASS etc)

EXAMPLE 3 :

Using ruler and compass, construct a 30o angle.

Make sure there are signs of “intersection of 2 cicles” to prove you used the compass.

You can use the protractor to double check it is a 30o angle.
