1Which personal protective equipment (PPE) pair is most appropriate when diluting concentrated acid in a school science laboratory?
A.Lab coat and closed shoes only
B.Safety goggles and gloves, with lab coat
C.Gloves only
D.Face mask only
Explanation: Diluting concentrated acid risks splashes that can injure eyes and skin, so safety goggles, chemical-resistant gloves and a lab coat are required together with careful acid-into-water technique.
2A chemical bottle is labelled with a skull-and-crossbones hazard pictogram. What does this primarily warn about?
A.The substance is flammable
B.The substance is toxic/acute toxicity hazard
C.The substance is an oxidiser
D.The substance is compressed gas
Explanation: The skull-and-crossbones GHS pictogram indicates acute toxicity — the substance can cause serious harm or death if swallowed, inhaled or absorbed.
3When mixing concentrated sulphuric acid with water, which procedure is correct and safest?
A.Add water rapidly into concentrated acid
B.Add concentrated acid slowly into water with stirring
C.Mix equal volumes poured simultaneously
D.Heat the acid first, then add water
Explanation: Always add acid to water slowly with stirring so the heat of dilution is absorbed by the larger water volume, reducing violent boiling and splashing.
4Which extinguisher type is generally unsuitable for a liquid organic-solvent fire in the laboratory?
A.Dry powder extinguisher
B.Carbon dioxide extinguisher
C.Water jet extinguisher
D.Foam extinguisher designed for flammable liquids
Explanation: A water jet can spread burning organic solvents and does not smother the vapour; CO₂, dry powder or appropriate foam are preferred for Class B liquid fires.
5For an adult casualty who is unresponsive and not breathing normally, what is the recommended CPR compression-to-ventilation ratio taught in basic first aid?
A.15 compressions : 2 breaths
B.30 compressions : 2 breaths
C.5 compressions : 1 breath
D.50 compressions with no breaths
Explanation: Standard basic life support for adults uses cycles of 30 chest compressions followed by 2 rescue breaths, with compressions at about 100–120 per minute.
6A student suffers a minor thermal burn on the forearm from hot glassware. What is the immediate first-aid action?
A.Apply butter or oil to the burn
B.Cool the burn under clean running water for about 20 minutes
C.Break any blisters immediately
D.Cover tightly with adhesive plaster only
Explanation: Cooling under clean running water for about 20 minutes reduces tissue damage and pain; do not apply grease, and leave blisters intact.
7Which measurement best estimates resting pulse rate in beats per minute if 18 beats are counted in 15 seconds?
A.18 bpm
B.36 bpm
C.72 bpm
D.90 bpm
Explanation: Pulse rate (bpm) = beats counted × (60 / counting time in seconds) = 18 × (60/15) = 18 × 4 = 72 bpm.
8BMI is calculated as mass (kg) divided by height (m) squared. A student of mass 54 kg and height 1.50 m has BMI closest to which value?
A.24.0
B.36.0
C.27.0
D.22.5
Explanation: BMI = 54 / (1.50)² = 54 / 2.25 = 24.0 kg m⁻², which is within the commonly cited normal range for adults.
9Which instrument is used to measure arterial blood pressure in a school health practical?
A.Thermometer
B.Sphygmomanometer (with stethoscope)
C.Barometer
D.Hygrometer
Explanation: A sphygmomanometer (blood-pressure cuff), often used with a stethoscope, measures systolic and diastolic arterial pressure in mmHg.
10A casualty is choking, conscious, and unable to speak or cough effectively. What should a trained first-aider do next after encouraging coughing fails?
A.Give water to drink immediately
B.Perform back blows and abdominal thrusts (Heimlich manoeuvre) as trained
C.Lie the person flat and start CPR at once
D.Ignore and wait for spontaneous recovery
Explanation: For severe choking in a conscious adult, trained responders deliver back blows and abdominal thrusts to dislodge the obstruction; CPR begins only if the casualty becomes unresponsive.

About the SPM Science Exam

SPM Science (subject code 1511) is the core KSSM Science subject sat at the end of Form 5. It is examined in two written papers: Paper 1 (1511/1) with 40 objective multiple-choice questions in 1 hour 15 minutes, and Paper 2 (1511/2) with structured and open-response items worth 80 marks in 2 hours 30 minutes (confirmed in the SPM 2025 timetable and LP assessment format). There is no separate practical Paper 3 for Sains 1511. The syllabus spans Form 4 (12 learning fields) and Form 5 (9 learning fields) under themes of scientific method/safety, maintenance of life, exploration of elements, energy and sustainability, and earth/space technology. Results are reported as a single grade on the 10-band A+ to G scale. Official papers are bilingual; this free practice bank is an English-language MCQ study adaptation focused on Paper 1-testable knowledge, calculations and data interpretation — not an official Lembaga Peperiksaan instrument.

SPM Science Study Tips from Top Performers

1Memorise laboratory hazard symbols, PPE, and the correct first-aid response for burns, bleeding, choking and CPR sequences before tackling application items.
2Drill motion formulae (v = u + at, s = ut + ½at², v² = u² + 2as) and pressure formulae (P = F/A, liquid pressure = hρg) until unit conversions are automatic.
3For rate of reaction, link each factor (concentration, temperature, surface area, catalyst) to collision theory and practise reading graphs of volume of gas versus time.
4Learn Mendelian monohybrid ratios (3:1 phenotype, 1:2:1 genotype) and sex determination (XX/XY) with Punnett squares for genetics items.
5Compare ionic versus covalent substances, electrolyte versus non-electrolyte, and anode/cathode products in electrolysis tables used in Paper 1.
6Practise food tests (Benedict's, iodine, Biuret, ethanol emulsion) and food-preservation methods as high-frequency Form 5 nutrition items.
7Work through recent trial and past-year Science 1511 papers, then review Kupasan Mutu Jawapan (KMJ) guidance for the exact keywords examiners expect on Paper 2.
