WBCHSE HS Vocational Automobile study plan

Sequence the four strokes of a four-stroke SI engine and the corresponding piston, valve and ignition events, sketching each stroke from memory

Distinguish petrol (SI) and diesel (CI) combustion and list the major components of each engine system (fuel, cooling, lubrication, intake and exhaust)

Identify and name at least 25 workshop hand tools and safety equipment, stating the correct use and one misuse of each

Demonstrate and write down the safe procedure for jacking, supporting and working under a raised vehicle, plus fire-extinguisher and PPE rules

Classify the main engine sub-assemblies (cylinder head, block, piston-rod assembly, crankshaft, valve train) and state the function of each

Explain the construction and function of cylinder head, cylinder block, piston, piston rings, gudgeon pin, connecting rod, crankshaft and flywheel

Describe valve timing, valve clearance and the purpose of the camshaft and valve train, and state typical valve-clearance checking steps

Outline the cooling system (radiator, thermostat, water pump, coolant flow) and lubricating system (oil pump, filter, galleries) with component functions

List the standard steps for engine removal, dismantling, inspection, reassembly and refitting, including torque-sequence and marking practices

Diagnose three common engine faults (overheating, low oil pressure, excessive oil consumption) from symptoms to likely causes

Explain the function and construction of clutch, gearbox, propeller shaft, universal joint, differential and final drive, and trace the power flow from engine to wheels

Compare manual and automatic transmission layouts and describe the role of the torque converter

Describe steering geometry terms (camber, caster, toe-in, king-pin inclination) and their effect on tyre wear and steering feel

Explain suspension types (leaf spring, coil spring, MacPherson strut, wishbone) and the function of shock absorbers

Identify common transmission and steering faults and match each to a component-level cause

Compare drum and disc brake construction and explain hydraulic braking, master cylinder, wheel cylinder, brake fluid and bleeding procedure

Describe the role of ABS, parking brake and brake proportioning in vehicle control, and explain fade and its causes

Explain vehicle dynamics basics: weight transfer under braking and cornering, stopping distance factors, and tyre grip limits

Identify and correctly use measuring instruments: vernier caliper, micrometer, dial gauge, feeler gauge, torque wrench and tyre-pressure gauge

Select appropriate materials for engine and chassis components (cast iron, aluminium alloy, steel grades, composite) and justify each choice

Explain the battery, starter motor, alternator and charging circuit, and trace current flow during cranking and charging

Describe ignition systems (conventional and electronic) and the function of spark plugs, coils and ignition timing

Identify lighting, horn, wiper, indicator and instrument-cluster circuits and the purpose of fuses, relays and switches

Explain the role of sensors and actuators (crank, cam, oxygen, temperature, throttle position) in engine management and list common ECU inputs and outputs

Practice safe electrical testing: multimeter voltage, resistance and continuity checks, and correct battery charging and jump-starting procedure

Build a preventive-maintenance schedule listing service intervals for oil, filters, coolant, brake fluid, belts, tyres and battery checks

Apply a structured diagnostic method (symptom, verify, isolate, test, repair, confirm) to at least three electrical and three mechanical faults

Interpret common diagnostic trouble codes and explain how scan tools read live sensor data

Perform and document a pre-delivery inspection checklist covering fluids, lights, brakes, tyres and road test

Explain emission-control components (catalytic converter, PCV, EGR) and their role in passing emission checks

Explain the legal and safety obligations of a small auto workshop: waste oil disposal, PPE, lifting safety and record keeping

Draft a simple business plan for a two-bay service workshop covering services offered, pricing basis, tools required and break-even estimate

Prepare a customer communication script for explaining a fault, quoting cost and handling a complaint professionally

Write a CV and cover letter for an automotive technician role, listing trade skills and certifications

Describe the roles and responsibilities of a technician, service advisor and workshop supervisor, and the importance of job cards and invoicing

Revise all eight domains using a self-made one-page summary sheet per domain, prioritising engine, transmission and electrical

Complete at least 120 practice questions across all domains under timed conditions and log every wrong answer with the correct reasoning

Re-demonstrate the five most error-prone practical skills (torque sequence, brake bleeding, multimeter use, valve clearance, measuring with micrometer) and self-assess

Recite the key formulas, definitions and safety rules from memory in a 30-minute self-test

Plan exam-day strategy: question order, time allocation per section and how to handle multi-part practical questions
