COREN Electrical exam-day guide

COREN Electrical · Prepare for the day ahead.

Your checklist

Admission letter / appointment confirmation

Print or download the confirmation the testing provider sent you. It normally shows your name, candidate or registration number, test centre and start time. Check that the spelling matches your ID exactly; if it does not, contact the provider before test day.

Valid government-issued photo ID

Bring the original document (not a photocopy or a photo on your phone) whose name matches your registration. Confirm with the provider which ID types are accepted and whether a second piece of ID is required.

Know the venue, entrance and travel time

Do a route check the day before: exact building, which entrance is open for candidates, and how long the journey takes at that hour. Add a buffer for security screening and registration queues.

Arrive early within the provider's stated window

Most computer-based testing centres expect candidates to report well before the scheduled start for identity checks and seat allocation. Confirm the exact reporting time and late-arrival cut-off with the provider; do not assume you will be admitted after it.

Permitted calculator and its status

Check the current COREN examination instructions for whether a calculator is allowed, and if so which models. If the test platform provides an on-screen calculator, do not bring your own. Confirm with the provider rather than relying on hearsay.

No unauthorised electronic devices

Phones, smart watches, earbuds and similar devices are almost always banned from the test room. Leave them at home or use the centre's storage if one is offered; confirm the storage policy with the provider.

Transparent water bottle and any permitted comfort item

Rules on drinks, snacks and medication vary by centre. If you need medication or an access arrangement, request it in advance through the provider's accommodation process rather than raising it on the day.

Review the current syllabus and exam format

Re-read the official COREN syllabus and the provider's candidate information so you know the number of questions, time allowed, and whether questions are grouped by topic. Do not rely on remembered formats from earlier years.

Prepare a one-page formula and units sheet

Condense key relationships (Ohm's law, power, three-phase quantities, transformer and motor relations, cable sizing inputs) plus SI prefixes and unit conversions onto a single sheet for the final revision pass.

Practise under timed conditions

Do at least one full-length timed set in the last three days so you know your pace per question and your habit for flagging and returning to hard items.

Plan sleep and food for the night before

Set two alarms, avoid a late-night cram, and eat a normal breakfast. Fatigue costs more marks than one extra hour of revision.

Read the provider's day-of rules once more

Confirm break policy, scratch paper or note-board provision, and the procedure if the test platform fails mid-session. These are provider-specific; check the official candidate handbook.

Plan the day

72 hours before

Switch from learning new material to consolidating. Work through the official syllabus topic by topic and mark any area you cannot explain from memory. Spend the remaining time only on those gaps.

72 hours before

Do one full timed mock under exam conditions: no phone, no notes, single sitting. Mark it, then classify every wrong answer as a knowledge gap, a misread, or a calculation slip. The classification tells you what to fix.

48 hours before

Drill calculation-heavy topics with a written method: write the formula, substitute with units, compute, then sanity-check the magnitude. Most avoidable losses in electrical papers come from unit errors (mA vs A, kVA vs VA, line vs phase values).

48 hours before

Rehearse standard safety and regulation content that is easy to recall but easy to muddle: earthing and bonding terms, protective device coordination, isolation and lock-out procedure, and the difference between design limits and operational limits.

24 hours before

Confirm logistics: venue, reporting time, ID, admission letter, travel plan and what you are allowed to bring. Resolve any doubt by contacting the provider now, not in the morning.

24 hours before

Do a light review only: your one-page formula sheet, unit conversions, and a short list of recurring traps (line versus phase, rms versus peak, power factor sign, per-unit bases). Stop studying in the early evening.

24 hours before

Prepare clothes and bag, charge nothing you are not allowed to bring into the room, set alarms, and aim for a full night's sleep.

Morning of

Eat a normal breakfast, leave earlier than the map suggests, and arrive within the reporting window. Keep the last hour calm: skim your formula sheet, do not start a new topic.

At registration

Present your ID and admission documents, follow the centre's instructions on personal items, and note where the invigilator sits and how to attract attention without disrupting others.

First minutes of the test

Read the on-screen instructions and confirm the timer and question count match what you expected. If anything is wrong, raise it with the invigilator before you start answering.

During the test

Answer in passes: first pass for questions you can do quickly, flag the rest, then return. Never leave a blank if there is no penalty for guessing; eliminate options first.

During the test

For calculations, write the given values with units before choosing a formula, then check the answer's order of magnitude against engineering sense. If two answers differ only by a factor of 3 or root-3, you are probably being tested on line versus phase.

Final minutes

Use remaining time to check that every question has an answer and that flagged items were revisited. Submit deliberately and confirm the on-screen acknowledgement before leaving.

Rules to check

  • Identity: bring the original government-issued photo ID whose name matches your registration exactly. A mismatch, an expired document, or a photocopy can bar you from sitting; confirm accepted ID types with the provider in advance.

  • Admission timing: report within the provider's stated window. Centres commonly refuse entry after a cut-off once the test has started, and fees are typically not refunded for lateness. Confirm the exact reporting time and cut-off with the provider.

  • Prohibited items: phones, smart watches, earbuds, notes and unauthorised calculators must not enter the test room. Follow the centre's storage instructions; if storage is not offered, leave such items at home. Confirm the current device and calculator policy with the provider.

  • Breaks: scheduled and unscheduled break rules are set by the testing provider, and the clock may or may not stop. Do not assume you can leave and return freely; ask the invigilator before the test begins.

  • Scoring: check the current official candidate handbook for how the paper is scored, whether wrong answers are penalised, and what the pass standard is. Do not rely on second-hand claims about negative marking or pass marks; confirm with the provider.

  • Conduct: no communication with other candidates, no sharing of materials, and no attempt to record or remove test content. Suspected misconduct is handled under the provider's rules and can lead to cancellation of results.

  • Technical problems: if the platform freezes or the screen fails, stop and raise your hand immediately so the incident is logged. Do not attempt to fix equipment yourself; the invigilator's record is what supports any later remedy.

  • Results and queries: keep your confirmation and any incident reference. If you need to query a result or a day-of problem, follow the provider's published appeals or enquiry procedure within its stated deadline.
