How You Are Actually Tested
Mathematics assesses three main cognitive levels:
Knowledge (30%)
What it tests:
Recall of rules, procedures, definitions, and facts
Simple computations
Constructions and drawings
Direct recall from memory
Example: "What is the formula for the area of a circle?"
Comprehension (40%)
What it tests:
Algorithmic thinking
Translation between mathematical representations
Application of algorithms to familiar problems
Use of procedures with understanding
Example: "Calculate the area of a circle with radius 5 cm."
Reasoning (30%)
What it tests:
Translation of non-routine problems into mathematics
Combination of multiple algorithms
Making inferences and generalisations
Justification and analysis
Example: "A farmer needs to fence a circular field. If the cost of fencing is $10 per metre, and the field has an area of 100 m², what will the total cost be?"
Common Mistakes
Many students lose marks on Mathematics because of these errors:
Not showing working: even if the final answer is wrong, method marks are still awarded
Forgetting units: always include cm, m², kg, etc. in the answer
Careless arithmetic: check calculations twice, especially in multi-step problems
Misreading the question: read carefully and answer exactly what is asked
Rounding too early: keep extra decimal places during working, round only the final answer
Ignoring significant figures: match the precision of the question
Not using appropriate formulas: memorise the formulas needed
Poor diagram interpretation: always use diagrams provided to guide your work
Incomplete explanations: for reasoning questions, justify each step
Running out of time: practise time management with past papers
Study Strategy
Master Calculations
Fluency is required in:
Arithmetic with fractions and decimals
Percentage calculations
Mole-like problem solving (consumer arithmetic, statistics)
Algebraic manipulation
This is non-negotiable. Spend time drilling these skills.
Memorise Key Formulas
Know these by heart:
Area and perimeter formulas
Volume and surface area formulas
Trigonometric ratios and laws
Quadratic formula
Mean, median, mode formulas
Distance and gradient formulas
Practice with Structure
When solving problems:
Read carefully: identify what is given and what must be found
Choose a method: select the appropriate formula or technique
Show all working: write every step
Check the answer: does it make sense? Is the unit correct?
Use Past Papers
This is the most effective study method:
Work through past papers under exam conditions
Mark your work against the scheme
Identify patterns in question types
Focus on topics where you lose marks
Build speed and confidence
Understand, Don't Memorise
Deep understanding includes:
WHY a formula works
HOW to apply it to different situations
WHEN to use one method over another
Memorisation alone will not give you a high grade.
Group Topics by Difficulty
Start with topics you find easier
Build confidence
Then tackle harder topics
Revisit weak areas regularly
Final Insight
Mathematics is a skill-based subject. It requires:
Accuracy: precision in calculation and language
Clarity: clear working and logical explanation
Consistency: regular practice and review
Most students lose marks because:
Their calculations are careless
Their explanations lack detail
Their working is hard to follow
They do not manage their time effectively
Fix these habits, and your grade improves immediately.
The path to success is simple: understand the concepts, practice consistently, and learn from your mistakes.
