Sample NSSCO Motor Mechanics 6189 Practice Questions

Try these sample questions to test your NSSCO Motor Mechanics 6189 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In an automotive workshop, a safety hazard related to tools is most likely to occur when:
A.Tools are damaged, incorrectly used, or left where they can cause injury
B.Tools are stored in a labelled shadow board after use
C.Torque wrenches are calibrated on schedule
D.Only insulated screwdrivers are used on live circuits
Explanation: The NSSCO Motor Mechanics syllabus requires learners to identify safety hazards linked to tools and name preventative measures. Damaged, misused or poorly placed tools commonly cause cuts, impact injuries and secondary accidents.
2A cluttered, oily workshop floor is primarily a hazard of the:
A.Working surface
B.Catalytic converter
C.Transfer box
D.Printed circuit board
Explanation: The syllabus groups workplace safety hazards under tools, working surface and materials. Oil and clutter on floors create slip and trip risks on the working surface.
3Noise and vibration in a motor mechanics workplace are classified in the syllabus as:
A.Physical health hazards
B.Only biological hazards
C.Only stress hazards
D.Electrical units of measurement
Explanation: Specific objectives list physical hazards including noise, vibration, heat/cold, manual handling and sun. These differ from chemical, biological and stress hazard groups.
4Petrol vapour, used engine oil and battery acid are examples of workplace:
A.Chemical hazards
B.Synchromesh units
C.Pilot bearings
D.Selector forks
Explanation: Chemical hazards in the syllabus include solids, liquids and gases. Automotive workplaces routinely expose learners to fuels, lubricants and corrosive battery electrolyte.
5According to the Motor Mechanics syllabus, HIV awareness in the workplace falls under:
A.Biological hazards
B.Torque conversion
C.Automatic transmission layout
D.Lighting circuit design
Explanation: Biological hazards listed include micro-organisms, insects, animals and HIV. Learners must identify such health hazards and preventative measures.
6Manual handling of heavy gearboxes without planning lift technique mainly increases risk of:
A.Musculoskeletal injury from physical strain
B.Incorrect Ohm’s law calculation
C.Wrong vernier reading units
D.Falsifying portfolio photographs
Explanation: Manual handling is listed among physical hazards. Poor lifting of heavy components can cause back and muscle injuries; preventative measures include team lifts, equipment and correct technique.
7Stressful working conditions in the syllabus are treated as:
A.Stress hazards that can affect health and safe performance
B.A substitute for PPE
C.Proof that a vehicle is roadworthy
D.A type of gasket material
Explanation: The safety topic requires identification of stress hazards arising from stressful working conditions and related preventative measures, recognising psychosocial workplace risk.
8Leaving flammable rags soaked in solvent on a hot exhaust manifold is mainly a:
A.Materials-related fire and chemical exposure hazard
B.Normal clutch bleeding procedure
C.Required portfolio photographic method
D.Standard synchromesh test
Explanation: Materials hazards include unsafe storage or placement of chemicals and contaminated waste. Solvent-soaked rags near hot surfaces create fire and fume risks that must be prevented.
9A preventative measure for grinding or cutting work that produces flying particles is to:
A.Wear suitable eye protection and keep guards in place
B.Remove all eye protection to see better
C.Disable machine guards for faster work
D.Store used grinding wheels in fuel
Explanation: Tool and working-surface safety includes PPE and guarding. Eye protection and intact guards reduce injury from abrasive and cutting debris.
10When diagnosing an electrical fault near a running engine, a key safety consideration is:
A.Avoiding entanglement with rotating parts and isolating energy where required
B.Removing the catalytic converter first in every case
C.Ignoring customer communication forms
D.Using only wooden micrometers
Explanation: Workshop safety combines tool, surface and materials awareness with physical hazards around heat, noise and rotating assemblies. Safe electrical diagnosis also means controlling unexpected movement and energy.

About the NSSCO Motor Mechanics 6189 Exam

NSSCO Motor Mechanics (6189) is Namibia’s Ordinary Level senior secondary Motor Mechanics qualification for Grades 10–11. The NIED syllabus covers workplace safety, vehicle components and roadworthiness, tools and sealing materials, workshop communication, maintenance service, cooling and lubrication, clutch/transmission layouts, vehicle electricity and electronics, and units/measurements, with strong emphasis on safe practice and practical portfolio evidence.

Assessment

Paper 1 Written (2 hours, 100 marks, 50%): Section A ten short-answer questions (30 marks); Section B seven structured questions (70 marks). Paper 2 Practical Examination (3 hours, 50 marks, 25%): two DNEA-set maintenance/repair tasks, centre-assessed and externally moderated. Paper 3 Portfolio (about four terms, 50 marks, 25%): five practical tasks from Grade 10 second term to Grade 11 second term, typically an A4 folder with photographic and written evidence; centre-marked with DNEA moderation. Overall assessment objectives weight knowledge with understanding about 30%, analysis and problem solving 17.5%, interpret data 17.5%, practical skills 35%.

Time Limit

Paper 1: 2 hours; Paper 2: 3 hours; Paper 3: portfolio across about four terms (commence Grade 10 second term; complete by Grade 11 second term)

Passing Score

Grades A*–G (G = minimum satisfactory); below G is not recorded on the certificate

Exam Fee

A public DNEA per-subject national examination fee schedule was not confirmed from an official DNEA circular; confirm with DNEA or your examination centre. Do not use NAMCOL tuition fees as DNEA exam fees. (Directorate of National Examinations and Assessment (DNEA), Namibia)

NSSCO Motor Mechanics 6189 Study Tips from Top Performers

1Work from the official NIED NSSCO Motor Mechanics syllabus PDF — examiners mark to the specific objectives under each of the nine topics.
2Treat workplace safety (tools, surfaces, materials and health hazards) as non-negotiable before any practical or diagnosis questions.
3For Paper 2 and Paper 3, practise planning, safe tool use, maintenance/repair sequence and photographic/written evidence — MCQs alone cannot replace workshop skill or portfolio tasks.
4Learn cooling vs lubrication functions, clutch/transmission layout names, and Ohm’s law calculations with clear cause-and-effect wording.
5Use recent NSSCO examiners’ reports for Motor Mechanics 6189 to target weak theory and coursework moderation issues.
