COREN Craftsman study plan
COREN Craftsman · Give each week a clear focus.
8 weeks · About 7 hours per week
Engineering Craft Practice and Workshop Technology & Engineering Materials, Tools and Equipment
List and define the core hand-tool operations (marking out, sawing, filing, drilling, tapping, chipping) and state the safety precaution for each
Classify 20 common workshop materials (ferrous and non-ferrous metals, alloys, timbers, plastics) by composition and typical workshop use
Sketch a labelled layout of a typical fitting/machine shop and identify the purpose of each workholding and marking-out item
Solve 10 numerical problems on linear measurement, tolerance and allowance using vernier caliper and micrometer readings
Your checkpoint
A 2-page personal reference sheet covering hand-tool operations, a 20-material classification table and worked measurement examples
Engineering Craft Practice and Workshop Technology & Engineering Materials, Tools and Equipment
Describe the working principle, parts and safe operating procedure of the centre lathe, drilling machine and pedestal grinder
Explain cutting-tool geometry (rake, clearance, cutting-edge angles) and match tool material (HSS, carbide, carbon steel) to application
Calculate spindle speed and feed from cutting-speed data for turning and drilling operations
Identify the heat-treatment processes (annealing, normalising, hardening, tempering, case hardening) and state the property change each produces
Your checkpoint
A one-page speed-and-feed calculation worksheet with 8 solved problems plus a tool-material selection table
Engineering Craft Practice and Workshop Technology & Engineering Materials, Tools and Equipment
Distinguish brazing, soldering and welding and select the correct process for three given joint scenarios
Describe the safe set-up, PPE and shutdown sequence for arc welding and gas welding
Explain the causes and remedies of five common fitting and machining defects (taper, ovality, chatter, poor surface finish, thread damage)
Outline preventive maintenance tasks and lubrication schedules for three common workshop machines
Your checkpoint
A defect-cause-remedy matrix covering at least 10 workshop defects with the corrective action for each
Engineering Drawing and Technical Communication
Apply first-angle and third-angle orthographic projection conventions and state the difference between them
Produce a fully dimensioned three-view orthographic drawing of a simple stepped block from an isometric sketch
Read and interpret section views, hidden detail and conventional representation of threads and holes
Calculate and apply limits, fits and tolerances (clearance, interference, transition) to a shaft-and-hole pair
Your checkpoint
A hand-drafted or CAD three-view orthographic drawing of a stepped block, correctly dimensioned, with a limits-and-fits calculation attached
Engineering Drawing and Technical Communication & Engineering Regulation, Ethics and Safety Practice in Nigeria
Interpret engineering drawing symbols for surface finish, welding, geometric tolerancing and datum references
Draw and label an assembly drawing from a set of component drawings, including a parts list
List the statutory and regulatory bodies relevant to engineering practice in Nigeria (COREN, SON, NIS, and relevant federal ministries) and state each body's core mandate
Explain the COREN registration pathway, categories of registration and the engineer's obligations under the enabling law
Your checkpoint
A one-page summary of Nigerian engineering regulatory bodies with mandates, plus a completed practice assembly drawing with parts list
Engineering Regulation, Ethics and Safety Practice in Nigeria
State the key duties and professional conduct obligations of a registered engineer, including competence limits and conflict-of-interest disclosure
Apply the correct ethical decision in 10 short workplace scenarios (bribery, sign-off pressure, unsafe design, plagiarism of drawings)
Outline the requirements of the Factory Act and the roles of HSE officers, safety committees and incident reporting
Describe risk assessment (hazard identification, likelihood, severity, control hierarchy) and apply it to a workshop task
Your checkpoint
A completed risk assessment for a workshop machining task plus written answers to 10 ethics scenarios with justification
Engineering Craft Practice and Workshop Technology & Engineering Drawing and Technical Communication & Engineering Materials, Tools and Equipment & Engineering Regulation, Ethics and Safety Practice in Nigeria
Complete a 60-question timed mixed-domain mock test and score each domain separately
Diagnose the two weakest topics from the mock and re-study them using targeted notes
Redo every missed calculation question until each is solved correctly without notes
Recite from memory the safety precautions for the five highest-risk workshop activities
Your checkpoint
A mock-test score report by domain with a written remediation plan for the two weakest areas
Engineering Craft Practice and Workshop Technology & Engineering Drawing and Technical Communication & Engineering Materials, Tools and Equipment & Engineering Regulation, Ethics and Safety Practice in Nigeria
Complete two further full-length timed mock tests under exam conditions
Review all flagged and previously missed questions and confirm each is now understood
Summarise each domain onto a single revision card of key formulas, standards and regulations
Rehearse exam timing and question-allocation strategy for a 4-domain paper
Your checkpoint
Final revision card set for all four domains plus a log of mock scores showing improvement from week 7
Milestones
Week 2: Score at least 70% on a self-set 20-question quiz on workshop technology and materials, including at least 6 of 8 speed-and-feed calculations correct
Week 4: Produce a correctly projected, fully dimensioned three-view drawing marked against a self-made checklist of at least 10 drawing conventions
Week 6: Score at least 75% on a 25-question quiz covering drawing interpretation and Nigerian regulation/ethics, with all ethics scenarios answered and justified
Week 8: Achieve at least 70% overall on the final full-length mock with no single domain below 60%
